Product Description

The Whiteline KCA470 Rear Upper Inner Control Arm Bushing Kit is a performance suspension component engineered for the Mitsubishi Lancer Evolution X model range from 2008 through 2015. These polyurethane bushings replace the factory rubber units at the rear upper inner control arms to reduce unwanted movement, improve chassis responsiveness, and help maintain more predictable handling characteristics during both street and track driving. Compared to OEM rubber bushings, the heavier duty design offers greater resistance to deflection under load and long-term durability.

This kit includes two reinforced polyurethane bushings and fits directly into the upper inner rear control arm mounting positions. Installation typically takes around 2.5 hours and may benefit from professional suspension service. After installation, a wheel alignment check is recommended to ensure proper rear suspension geometry. The KCA470 provides a noticeable improvement in rear feel and stability for enthusiasts seeking sharper handling and enhanced suspension control on Evo X platforms.
