SPL length adjustable links allow fine tuning of rear bumpsteer and anti-squat characteristics. These arms are designed for use in high-performance street and race vehicles. 

SPL latest version of the Rear Traction Arm is machined from Billet 6061-T6 Aluminum. The main arm is slotted to allow the use of pinch bolts with SPL 360 degree Rotating Clamps on SPL exclusive Double Adjuster, which is comprised of electroless nickel plated 4130 Chromoly. Blue Anodized Titanium hardware reduce even more unsprung weight and prohibit corrosion, while offering quick, easy adjustment and without compromising strength.

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 to 325ºF, offering robust reliability for both street and track use.
