Product Description

The **Whiteline W0590 Rear Upper Front Inner Control Arm Bushings** kit is a suspension bushing upgrade designed specifically for Mitsubishi Lancer Evolution IV through IX generations (1996-2007). These bushings replace the factory rubber units in the rear suspension's upper control arm front inner position. Made from high-durability synthetic elastomer, the W0590 bushings provide improved resistance to oil, grease, ozone, and weathering while maintaining elasticity that helps control unwanted movement under load.

Upgrading to Whiteline bushings can improve rear chassis stability, rear wheel alignment consistency, and steering feedback during cornering, acceleration, and braking. Protective plating on the included components helps resist corrosion, and Whiteline backs this product with a **lifetime limited bushing warranty**, reflecting confidence in material longevity. These bushings are a direct replacement fit - ideal for daily drivers, spirited street cars, and performance builds for Evolution owners seeking enhanced suspension feedback and reduced compliance in the rear control arm mounts.
