Whiteline W0591 is a polyurethane rear upper control arm bushing replacement for the Mitsubishi Lancer Evolution VII, VIII, IX.
Why upgrade to polyurethane?
- Reduces deflection vs. worn rubber bushings — sharper steering response and better wheel control.
- Resists oil, road salt, and UV — outlasts OE rubber.
- Maintains alignment under load, especially during hard cornering.
