Racer X Fabrication HD Rear End Links 2008-2021 STI / 2008-2025 WRX | CNC Machined 6061-T6 Aluminum | Adjustable Rear Sway Bar Links
Overview
The Racer X Fabrication HD Rear End Links are engineered specifically for the 2008 and newer Subaru WRX and WRX STI models, designed to replace the OEM rear sway bar end links with a more robust, performance-oriented solution. By eliminating the factory rubber bushings and upgrading to a combination of spherical bearings and heim joints, these end links significantly improve handling precision, response, and driver feedback. This upgrade is ideal for Subaru enthusiasts seeking sharper chassis control and enhanced suspension performance without compromising daily drivability.
Built around a thicker CNC machined 6061-T6 aluminum body, these end links represent a substantial evolution over previous designs. The double adjuster mechanism allows for precise length tuning to optimize sway bar preload and suspension geometry. The pinch bolt locking system ensures the adjuster remains securely in place under all driving conditions. Racer X Fabrication’s commitment to quality is evident in the anodized black finish and zinc plated hardware, providing corrosion resistance and a clean, OEM+ appearance.
On the road or track, these HD Rear End Links deliver a noticeable increase in chassis rigidity and durability, translating to improved cornering stability and reduced body roll. Compatible with both OEM and aftermarket sway bars, they integrate seamlessly into Subaru WRX and STI suspension setups. This upgrade is a practical step for owners looking to maximize their vehicle’s handling potential while maintaining reliability and fitment specific to Subaru platforms.
