Timbren Active Off-Road Rear Bump Stop Kit for GX 550 (2024–Present)

The Timbren Active Off-Road Rear Bump Stop Kit is engineered for GX 550 owners who want improved suspension performance when exploring beyond paved roads. By replacing the factory rear bump stops with progressive Aeon rubber bump stops, it helps manage hard suspension impacts and delivers a more controlled response across challenging terrain.

During off-road driving, the rear suspension can experience sudden compression from ruts and uneven surfaces. Aeon bump stops progressively absorb these impacts, creating smoother engagement and reducing abrupt bottom-outs.

Repeated impacts can place significant stress on rear shocks, axle components, and suspension parts. By controlling compression forces, this system helps reduce the strain placed on critical hardware during demanding trail use.

A more progressive suspension response helps minimize sharp impacts transferred through the chassis. This improves ride comfort and vehicle composure during long trail days, remote expeditions, and technical off-road sections.

Unlike hydraulic bump stops that require servicing, rebuilding, or fluid maintenance, this kit uses durable rubber construction with no serviceable internal components. It provides consistent performance with virtually no upkeep.
