Tough Dog Nitro Gas Suspension Kit – Holden Colorado / Isuzu D-Max – Medium Rear Load 300kg+ Constant – No Bullbar / Alloy Bullbar / Steel Bullbar (TDK-HOL-003-D39A81)

A complete Tough Dog Nitro Gas suspension kit for the Holden Colorado and Isuzu D-Max, giving 40mm of lift front and rear. Controlled, comfortable ride for light and medium 4WDs.

These nitrogen gas shocks use multi-stage, velocity-sensitive valving. As the shock speeds up over small, sharp bumps like corrugations, the valving responds to keep the ride settled. A sensible, value-focused choice for lighter vehicles and leaf-sprung rear ends.

The rear springs are rated for a constant load of 300kg or more. Choose this option if weight stays in the vehicle every day, like a canopy, drawers, water tanks, tools or touring gear.
