Perrin Rear Endlinks w/ Polyurethane Bushing 2004-2007 STI / 2004-2008 Forester | Durable Polyurethane Bushings | Suspension Upgrade
Overview
The Perrin Rear Endlinks with Polyurethane Bushings are a direct upgrade designed to enhance the suspension performance of your Subaru WRX STI (2004-2007) and Forester (2004-2008). These endlinks replace the factory rubber bushings with high-quality, Teflon-lined polyurethane bushings pressed into CNC-machined aluminum arms, providing a firmer and more precise connection between your sway bar and chassis. This upgrade is ideal for enthusiasts looking to improve handling response and reduce unwanted flex, especially when running stiffer aftermarket sway bars.
Engineered with a focus on durability and performance, Perrin’s design philosophy centers on eliminating the common weaknesses found in OEM plastic and steel endlinks. The use of 6061 T6 aluminum arms combined with 95a durometer polyurethane bushings strikes a balance between stiffness and noise reduction, avoiding the harshness often associated with solid spherical bearings. The anodized finish and stainless Grade 8 hardware ensure corrosion resistance, making these endlinks suitable for all-weather driving conditions.
For Subaru owners, this upgrade translates into a more predictable and confident driving experience. By reducing sway bar flex and improving the connection to the chassis, the Perrin Rear Endlinks help your suspension respond more accurately to road inputs. This means better cornering stability and overall improved handling dynamics, whether on the street or the track. The longevity of these components also ensures they will last the life of your vehicle, providing consistent performance over time.
