Whiteline Rear Control Arm Lower Inner Bushings – 2003-2006 Mitsubishi Evo 8/9

Rebuild the Rear Lower Arm Inner Pivot on the Evo 8 and 9
The rear lower control arm inner bushing on the 2003-2006 Mitsubishi Evo 8 and 9 is a high-load position that takes simultaneous lateral and longitudinal forces under performance driving. Whiteline’s polyurethane replacement restores the precise rear lower arm geometry that the Evo’s performance reputation depends on.

Evo 8/9 Lower Arm Inner Wear
The rear lower arm inner bushing on the Evo 8/9 wears with the high loads of performance driving. Track use and hard street driving both accelerate wear. When worn, the arm develops angular play that changes rear camber and toe under load.

Inner Bushing with the Outer Kit
The W62951 inner bushing works alongside the W62950 inner/outer kit for a complete rear lower arm rebuild. For the most comprehensive improvement, replace all lower arm bushing positions simultaneously.

AWD Platform Geometry Sensitivity
On the Evo’s AWD platform, rear wheel geometry consistency directly affects how the AWD system manages traction. Precise rear arm bushings keep the geometry stable, giving the AWD system a consistent platform to work from.

The RallySport Take

A targeted rear lower arm bushing for the Evo 8/9. Budget an afternoon for the job — bushing replacement is not complicated but does require the correct press tools and clean installation technique. Apply grease to all polyurethane-to-metal interfaces and assemble at ride height for correct bushing set. The improvement in chassis feel is immediate and the polyurethane will outlast whatever rubber is in there now.
