What are the best defense lacrosse shafts for high school and college players. How do carbon fiber and metal options compare in strength and performance. Which brands offer the top defensive lacrosse shafts for long stick middies and close defenders.
The Evolution of Defense Lacrosse Shafts: From Metal to Carbon Fiber
The landscape of defensive lacrosse equipment has undergone a significant transformation in recent years. Gone are the days when metal shafts were the only option for defensemen and long stick middies. Today, players have a wide array of choices, ranging from traditional metal alloys to cutting-edge carbon fiber composites.
This evolution has been driven by advancements in materials science and a deeper understanding of player needs. Modern defense shafts are designed to offer the perfect balance of strength, weight, and feel, allowing players to perform at their best on the field.
The Rise of Carbon Fiber in Lacrosse
Carbon fiber has revolutionized the lacrosse shaft market, offering several advantages over traditional metal options:
- Exceptional strength-to-weight ratio
- Vibration dampening properties
- Ability to fine-tune flex and responsiveness
- Resistance to temperature changes
These properties have made carbon fiber shafts increasingly popular among high-level players who demand the utmost performance from their equipment.
Key Factors to Consider When Choosing a Defense Lacrosse Shaft
Selecting the right defensive shaft is crucial for maximizing your performance on the field. Here are the primary factors to keep in mind:
Material
Is carbon fiber always superior to metal for defensive shafts? While carbon fiber offers numerous benefits, some players still prefer the familiar feel and durability of metal shafts. The choice often comes down to personal preference and playing style.
Weight
How does shaft weight impact a defender’s performance? Lighter shafts offer increased maneuverability and quicker checks, while heavier options provide more power for body checks and ground balls. Finding the right balance is key.
Durability
Can a lightweight shaft withstand the rigors of defensive play? Modern manufacturing techniques have significantly improved the durability of both metal and carbon fiber shafts, allowing for lighter designs without sacrificing strength.
Grip
How important is shaft texture for defensive players? A good grip can make a significant difference in stick control, especially in wet conditions. Some shafts feature built-in textures, while others may require additional tape or grip enhancers.
Price
Are expensive shafts always better? While high-end options often offer superior performance, there are excellent mid-range shafts that provide great value for many players. It’s essential to consider your budget and skill level when making a decision.

Garant Blok is a market leader in mechanical anti-theft locks.
For twenty-five years, drivers have chosen it as the protection against theft of their cars. Ease of use, a high level of criminal resistance and an affordable price – these are the reasons for the trust of motorists.
How it works
The clutch is mounted on the steering shaft with screws. A stopper is inserted into the clutch and, in the closed state, rests against the steering column elements, blocking the possibility of turning the steering wheel. Unlocking the stopper is carried out by a reliable secrecy mechanism.
Anti-theft lock “Garant Blok”
Stopper
Made of hardened steel and 30 mm thick, which helps to protect the structure from drilling and sawing with power tools. It has several protection elements:
- steel canopy that protects the coupling hooks from sawing
- security mechanism
- hardened steel trap disc to protect the trap mechanism from drilling
- tight connection with the sleeve, which makes it impossible to knock out the stopper with a chisel
- latch groove that abuts against the lug on the sleeve protects against opening by bumping and probe
- hardened safety disc over the latch that breaks when attempting to drill out, locking the latch in the closed position
- hardened tungsten carbide pins located in the eccentric shaft to protect against drilling
Security mechanism
Garant steering shaft locks can be equipped with two security mechanisms.
You can learn more here – Comparison of secret mechanisms.
Coupling
Consists of two steel caps. Does not limit the functionality of passive safety systems. It has design features that increase the degree of protection:
- coupling covers are highly hardened to protect against rough mechanical impact and drilling of screws
- in the closed position, the stop completely covers the screws
- Protective disk made of hardened steel, inserted into the top cover of the coupling and blocking access to the stop elements connected to the coupling
- Coupling galvanized for corrosion protection
- The inner diameter of the hole in the coupling is 0.3 mm smaller than the diameter of the steering shaft, thus, when tightening the screws, a preload is formed that prevents the coupling from turning on the shaft
- screws have a maximum strength class of 12.9so that the coupling can be tightened to the correct torque
- Couplings with anti-clamping sleeves are installed on the steering shafts with a telescopic system, maintaining the passive safety of the car.
Thus, it turns out to achieve an ideal balance between the hardness and ductility of the metal, which allows protecting the “Garant Blok” from all types of mechanical stress.Product durability and versatility
- bollard has a service life of more than 10 years
- 5 year warranty
- withstands temperature fluctuations from -45°C to +85°C and with proper care (periodic washing of the lock part with WD-40 cleaner) is able to cope with work in an aggressive environment
- for ease of use, the stopper is equipped with a flexible PVC handle that is not exposed to heat or freezing and does not slip in the owner’s hand
- more than 300 car models, from budget to luxury, are equipped with the Garant Block lock, which makes it a universal anti-theft tool for most car owners 5

Cardan shaft
Cardan shafts (KV), along with cardan joints, intermediate supports and connecting devices, are elements of the vehicle’s transmission.
The cardan shaft is a unit that directly transmits torque (rotation energy) to the wheels.
Beginners sometimes confuse the concept of “cardan shaft” and “cardan transmission”. To prevent this from happening, it is important to learn the following things:
- The cardan shaft has two points of support, it does not have any intermediate supports.
- The cardan transmission may have several bearings and includes several cardan shafts.
Cardan shafts are easy to find on passenger vehicles (4-wheel drive and rear-wheel drive cars), light trucks, buses, dump trucks, trucks, truck cranes, loaders, tractors, ATVs. But in front-wheel drive cars, driveshafts are unpopular. It is difficult to achieve synchronous rotation of the shafts. An exception is transport with a HF with a CV joint.
Cardan shaft device
The main elements of the most popular modification of the device:
- Central shaft (cardan tube, axle). Hollow metal pipe. One piece detail. Structural element to which other parts are attached.
- Cross. It is important for the implementation of the function of controlling the angles of variable inclination and, accordingly, rotating elements. The correct range of tilt angles is 0 to 20 degrees. This is important so that the shaft does not interrupt rotation. High-quality crosses are made of alloy steel by hot stamping.
- Welding fork. Connecting element between intermediate and main shaft. It plays the role of a compensator for the height distance between the shafts. The value of a welded fork is especially easy to appreciate off-road. When selecting a fork for HF (for example, in case of replacement), it is important to consider the size of the cross, the bore diameter of the pipe, the maximum hinge angle and the type of fastening.
- Flange-fork hinge (cardan flange). The yoke flange is mounted in the area where the shaft is attached to the bridge. It consists of a flange (flat disc) and two horns, in which holes are made for the cross, for bolts. The fork is attached to the mating flange on the drive axles or gearbox. The most promising are yoke-flanges with 4 slotted “heels” in the areas of bolt installation and slots on the mating flanges. Such solutions are a guarantee of high-quality connection of nodes. When choosing a flange when replacing a part, it is important to consider the diameter of the holes and their number, the diameter of the flange itself.
- Slotted connection. Responsible for the transformation of the working length during movement. One point of the spline connection is fixed on the gearbox, the other on the gearbox. When the vehicle is forced to overcome potholes, pits, the interval between the fulcrum increases, and thanks to the spline connection, the cardan “stretches”.
Both forks, cross and spline form a so-called swivel joint. Its main task is to transmit torque with a changing angle.
Exception! On some SUVs, instead of a cross, you can find cardans with CV joints. In this case, there is no spline connection.
The KB-series device includes an elastic coupling. It helps smooth out torque fluctuations and compensate for axial and angular deviations.
Bearings
If we are talking not only about the cardan shaft, but also the cardan transmission as a whole, considering the device, we must not forget about the bearings. To maintain the cardan shaft in a technically correct position, an outboard metal bearing with a metal cage and a rubber cushion is installed on it.
It is the outboard bearing that takes on the load (axial, radial), provides rotation, rolling. This is one of the most stressed elements of the transmission, and therefore requires regular maintenance.
The intermediate bearing supports the main shaft and allows it to rotate in the required direction. Bearings in the form of a ring made of elastomer have the best damping properties.
What is the function of the cardan shaft?
HF is capable of performing two important functions.
- Basic. Transfer of torque from the gearbox or transfer case of the car to the rear wheels. The cardan allows you to gently transfer the moment from the transmission to the wheels, dampen vibration on the road, and ensure a smooth ride.
- Additional. Plays the role of a link between the steering column and rack. That is, it is already part of the steering mechanism. HF helps to improve steering sensitivity.
Thanks to the HF vehicle, even on rough roads, good acceleration is ensured.
KV is actually an optimizer for efficient unloading of the front wheels and a tool to reduce the risk of slipping.Cardan shaft types
Cardan shafts and cardan transmissions can be classified according to a number of criteria:
- According to the type of cardan transmission: open and closed KV. An open cardan is a separate element of the vehicle, a closed cardan is integrated into another unit. A common variant of closed CVs is their inclusion in the crankcase of the drive axle.
- By design: rigid cardan, ball cardan and cam-type cardan of equal angular speeds. The transmission of torque from the fork of rigid cardans is uneven. Therefore, the decision is also unpopular. It can only be found in some passenger cars. In commercial vehicles, you can often find ball joints (the most popular option) and cam-type cardans. A huge plus of ball cardans is dividing grooves that provide the optimal position of the balls in the plane. Functional, practical.
- By material. The base material of all HF is metal. The most popular option in our time is steel. Somewhat less common are cast iron and aluminum HF.
- Ability to compensate. Solutions that allow for compensation between the cardan centers of significant axial movements are classified as universal. If this is not possible, then we have simple HF.
- Kinematic properties. Asynchronous and synchronous. Asynchronous designs are popular solutions with a cross and a fork (standing on vehicles with rear wheel drive). Synchronous – solutions with a CV joint (they are on front-wheel drive vehicles, some models of all-wheel drive vehicles). Asynchronous transmission is noisier than synchronous transmission, but at the same time it is cheaper to manufacture and easier to maintain.
- By the number of supports. Most vehicles have three-bearing universal joints with one bearing that acts as a connector between the main and intermediate shafts. Two-support structures are somewhat less common (mostly they are mounted on trucks, a number of all-wheel drive cars). And even less often you can find three-support structures. This decision, as a rule, is inherent in Chrysler, Lexus.
- By the number of sections. Single-section (in fact, it is a pipe, at the end of which there are crosses and tips) and multi-section.
Checking the condition of the cardan shaft
Even if the car is operated in non-extreme conditions (driving on city roads), checking the condition of the driveshaft is needed every 5 thousand kilometers. When driving on dirt roads, a check is recommended even more often: every 3 thousand km. Special equipment has its own requirements. It all depends on what objects it is used on. When checking, the greatest attention is paid to the cross, which can begin to roll, seize, and also to the outboard bearing. The appearance of backlash after a certain run is a completely natural phenomenon.
Spline connection is also very vulnerable. First of all, because it is a moving mechanism that constantly encounters dynamic loads.
It is recommended to check the parts in the following order:
- Connecting elements (nuts, washers) of bearings, couplings, flange forks. It is important that not only all connections are in place, but that the tightening torques are in accordance with the requirements of the operating conditions.
- Couplings at the moment of shaft torsion. The presence of cracks on the couplings, and even more so breaks, is unacceptable. If there is such a problem, you need to change the part urgently.
- Spline connection at the moment of shaft rotation. Here it is important to understand if there are any backlashes. In order for the assessment of the state of the spline state to be as reliable as possible, it is advisable to perform rotation in both directions.
- Hinges. It is not enough just a visual inspection. It is necessary to place a screwdriver between the forks and thoroughly pump it. An unpleasant moment is, again, finding a backlash. In this case, you will have to put a new cross.
- Bearings. How the verification takes place is of fundamental importance. Skills matter. In order not to miss the backlash, you need to hold the HF with one hand, pull it in different directions with the other.
But if there is a suspicion of an imbalance in the HF, you can not do without diagnosing the node on the balancing stand. Especially, such a check cannot be dispensed with if constant vibrations are felt during the ride, and an unpleasant rattle regularly occurs when shifting gears.
Cardan shaft service
The traditional maintenance scheme is based on three operations:
- Shaft condition check (see above).
- Replacement of faulty parts (namely, replacement, restoration in the presence of backlash and cracks – an illiterate solution to the problem).
- Spline lubrication. When selecting a lubricant, pay attention to the welding load (responsible for extreme pressure properties). Expensive products are geared towards welding loads up to 3920 Newtons. For splines on HF on heavy freight transport, their use is only welcome. For passenger cars, lubricant for low-loaded splines is sufficient. Overpaying for the product here is inappropriate.
Some cars also need to lubricate the bearings of the KV crosses. But there are not very many vehicles that need such a procedure. These are vehicles with HF with a grease fitting (grease fitting). An example of a CV with a grease fitting is shown in the figure below.
Malfunctions of cardan shafts
The problem can occur both for the entire device, and only for its individual components, parts:
- Breakage of the welded fork. It occurs due to the initial incorrect installation of the cross, damage to the mounting holes for this part, destruction of the fork.
- Fork flange failure. It occurs due to wear, chips, cracks or damage to the mounting bolts.
- Bearing failure. More often – due to natural wear, mounting errors, constant contact of the bearing with dust, a driving style based on constant hard shifting.
- Deformation, curvature KV. Based on the inspection, the master decides whether the problem can be solved by purely mechanical restoration or a number of elements need to be replaced.
- Vibration of the propeller shaft. Most often, this is a “response” to incorrect alignment of parts, an increase in gaps between parts when the vehicle is operated in difficult operating conditions, incorrect repairs (unprofessional welding work).
- Cardan begins to “ring”. The reasons may be different. If the support is damaged, the best option is to replace the cardan, if the protective boot is relaxed, it is enough to repair it by welding. The easiest option: a problem with the slot cover – just replace it with a new one.
Removing and installing cardan shaft
Car restoration and repair operations are associated with their dismantling and, on the contrary, installation on a transmission.
- Unscrew the bolts and nuts to remove the cardan flange from the gearbox.
- The cardan shaft has two points of support, it does not have any intermediate supports.
Thus, it turns out to achieve an ideal balance between the hardness and ductility of the metal, which allows protecting the “Garant Blok” from all types of mechanical stress.
High-quality crosses are made of alloy steel by hot stamping.
KV is actually an optimizer for efficient unloading of the front wheels and a tool to reduce the risk of slipping.
The base material of all HF is metal. The most popular option in our time is steel. Somewhat less common are cast iron and aluminum HF.
And even less often you can find three-support structures. This decision, as a rule, is inherent in Chrysler, Lexus.
For splines on HF on heavy freight transport, their use is only welcome. For passenger cars, lubricant for low-loaded splines is sufficient. Overpaying for the product here is inappropriate.
