SPL Parts Rear Traction Arms for 2015-2021 Subaru WRX/STI - SPL RTR GK
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2015-2021 Subaru WRX and WRX STI models including Base, Premium, Limited, and special editions.
SPL Parts Rear Traction Arms increase chassis stability and steering response by eliminating the deflection inherent in factory rubber bushings. These adjustable links allow for precision fine-tuning of rear bumpsteer and anti-squat characteristics, effectively reducing wheel hop during hard launches and improving predictability under heavy braking. Engineered for both high-performance street use and competitive racing, these arms replace the compliant OE components with rigid, maintenance-free spherical bearings.
Each arm is CNC-machined from Billet 6061-T6 Aluminum. The design features a 360-degree Rotating Clamp on an exclusive electroless nickel-plated 4130 Chromoly Double Adjuster, allowing for quick and easy length adjustments while the arms are still bolted to the vehicle. Blue Anodized Titanium hardware further reduces unsprung weight and provides exceptional corrosion resistance without sacrificing structural integrity.
