Whiteline Shock to Control Arm Bushings – 2003-2006 Mitsubishi Evo 8/9

Whiteline Shock to Control Arm Bushings – 2003-2006 Mitsubishi Evo 8/9

Fix the Damper Mount on Your Evo 8 or 9
The shock absorber to control arm bushing on the 2003-2006 Mitsubishi Lancer Evolution 8 and 9 is the lower mounting point of the rear damper at its control arm connection. When this bushing wears or deteriorates, the damper base can develop angular play in the control arm mount, affecting both the geometry and the effectiveness of the rear damper. Whiteline’s polyurethane replacement restores correct damper positioning and control arm geometry.

DETAILS

• Polyurethane compound for rear shock to control arm mount position
• Restores correct damper geometry and control arm positioning
• Reduces rear suspension compliance at the damper lower mount
• Fitment: 2003-2006 Mitsubishi Lancer Evolution VIII and IX
• Limited Lifetime Warranty

Why the Damper Mount Matters
The rear damper’s lower mount connects it to the rear suspension. When the mount bushing wears, the damper base can move in the mount under suspension loads — altering the effective damper angle, reducing its working efficiency, and allowing geometry changes at the control arm that shouldn’t occur. On an Evo used for track driving, this shows up as rear suspension inconsistency and a vague, imprecise character that doesn’t match the car’s reputation.

Evo Platform Bushing Wear Profile
The Evo 8 and 9 are used hard — track days, autocross, and spirited street driving are normal use cases for these cars. That use accelerates bushing wear throughout the rear suspension. The shock to control arm bushing is one of several positions that should be addressed as part of a comprehensive rear suspension refresh on any high-mileage or track-use Evo.

Comprehensive Evo 8/9 Rear Suspension Coverage
Whiteline covers the Evo 8 and 9 rear suspension with a full range of control arm bushings, trailing arm bushings, and geometry correction components. Doing the full range at once is the most efficient approach for a car being built for serious use.

Why Choose Whiteline

Whiteline has been engineering suspension components from their facility in Australia since 1979. Every product in their catalog is developed with a clear goal: measurable improvement in handling, stability, and tyre contact. Whiteline’s polyurethane bushings, sway bars, control arms, and alignment correction kits are engineered using finite element analysis and validated on track before they reach the market. Their components are direct-fit, bolt-on solutions designed for enthusiasts who want real performance gains without fabrication or custom work.

The RallySport Take

A targeted fix for a specific wear point in the Evo’s rear suspension. On a car this performance-oriented, correct damper mounting geometry is not optional. 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.
