BMW F2X/F3X Tension Rods (TR) provide a wide range of front caster adjustment, allowing precise alignment for optimal turn-in response and to compensate for variances between left and right caster. Low-friction, smooth articulating FK Spherical Bearings eliminate the stock mushy rubber bushing to provide a more responsive steering feel. Anti dive geometry can also be tuned with the use of our stainless steel spacersOur parts are engineered for maximum performance. Billet Aluminum alloy 2024 hex rods are precision CNC machined and gun drilled to reduce unsprung weight while maintaining high strength and stiffness. Our exclusive 360 degree Rotating Clamp design allows for easy access to quickly and precisely locking in your desired alignment settings. Blue Anodized Titanium hardware shaves even more unsprung weight from the arms and offers superior strength. FK Bearings Rod Ends are manufactured in Connecticut and JMX hardened high misalignment rod ends are used for superior strength and maximum articulation on the spindle connection. They feature a Teflon liner to provide quiet operation, low friction, smooth articulation and eliminates bushing deflection under load. The PTFE liner is chemically bonded to the inner diameter of the race. The liner offers a very high load carrying capacity and has greatly increased dynamic wear characteristics. The operating temperatures of the liner ranges from -65 º to 325 º F, offering robust reliability for both street and track use. Sold as a pair.
