Timbren Active Off-Road Front Bump Stop Kit for Toyota 4Runner (1990–2024)

The Timbren Active Off-Road Front Bump Stop Kit is designed for Toyota 4Runner owners who regularly tackle rugged trails, rocky terrain, and demanding overland routes. By replacing factory bump stops with progressive Aeon springs, it helps reduce harsh suspension impacts while improving overall control and comfort.

Progressive bump stops cushion heavy suspension compression by absorbing energy during bottom-out events. This creates smoother axle engagement while reducing the sharp impacts experienced with factory bump stops.

By minimizing harsh bottoming forces, the system helps reduce stress placed on suspension components, shocks, and mounting hardware. This added protection can help improve durability during repeated off-road use.

Unlike hydraulic bump stop systems that require periodic rebuilding or servicing, the Active Off-Road kit operates without fluids or scheduled maintenance. Once installed, it delivers consistent performance with no routine upkeep.

The Timbren Active Off-Road Front Bump Stop Kit gives Toyota 4Runner owners confidence by improving suspension performance, protecting critical components, and delivering smoother, refined off-road control.
