Our SPL Parts Tension Rods (TR) provide for adjustment of front caster, allowing you to change front caster to optimize the turn-in response and to compensate for variances between the left and right caster. Low-friction articulating 3/4" FK Spherical Bearings on our Tension Rods eliminate the stock mushy rubber bushing to provide a more responsive steering feel. Engineered for maximum performance, Large diameter (1 3/8") Billet 6061-T6 rods are precision CNC machined and gun drilled to reduce unsprung weight while maintaning high strength and stiffness. Our exclusive 4130 Chromoly Double Adjuster offers wide adjustment range and precise adjustment, and is also CNC gun drilled to reduce weight. Blue Anodized Titanium hardware shaves even more unsprung weight from the arms, without compromising strength.Custom 3/4" 3 piece FK Bearings Rod Ends manufactured in Connecticut 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 -65º
