Mitsubishi Triton MR Suspension Upgrade Guide

Improve load support, towing stability and rear suspension control with RoadActive Suspension for the Mitsubishi Triton MR. This guide covers compatible 2019–2024 models fitted with rear leaf springs.

Why Choose RoadActive Suspension for Your Mitsubishi Triton?

The Mitsubishi Triton MR is commonly used for work, towing, touring and everyday driving. Canopies, toolboxes, drawers, touring equipment and trailers can place additional demand on the factory rear suspension, particularly when weight is carried regularly.

RoadActive Suspension is a mechanical leaf spring assist system that works with the Triton’s existing rear leaf springs. It is designed to help reduce rear-end sag, improve vehicle stability and provide more controlled handling when carrying loads or towing.

Unlike airbags, RoadActive Suspension does not require compressors, airlines or ongoing pressure adjustments. The system operates automatically as the rear leaf springs move, providing progressive support when suspension demand increases.
