Description

Enhance your Subaru WRX or STI with the SPL Parts 2015+ Rear Traction Arms, engineered for high-performance street and race applications. Crafted from billet 6061-T6 aluminum, these arms provide increased stability and response by eliminating bushing deflection during hard acceleration and braking. The design includes adjustable links that allow precise tuning of rear bump steer and anti-squat characteristics, giving you optimal handling under various driving conditions. The main arm features a slotted construction to accommodate pinch bolts and 360-degree rotating clamps on the exclusive Double Adjuster, made from electroless nickel plated 4130 chromoly steel, ensuring durability and corrosion resistance. Blue anodized titanium hardware further reduces unsprung weight while maintaining strength and ease of adjustment.
