A complete 50mm lift for the Holden Colorado RG 4WD (2012-2020), built around Bilstein B6 Offroad shocks and pre-assembled ReadyStruts. It's developed to improve ride quality, handling and control across sealed roads, touring routes and off-road terrain.
The Bilstein B6 Offroad front shocks are paired with King Springs front coils and SuperPro strut mounts, assembled into ReadyStruts and matched to your front load. At the rear, Bilstein B6 Offroad shocks work with a Formula 4x4 leaf spring kit matched to your rear load, supplied with matching extended U-bolts and a SuperPro greasable eye and shackle kit. A SuperPro handbrake cable relocation kit is also included. See every part in the What's in the kit tab.
Why Bilstein B6 Offroad shocks
- 46mm monotube, high-pressure gas. Oil and gas sit in separate chambers, so damping stays consistent on corrugations and rough terrain, without the cavitation that affects twin-tube shocks.
- Digressive valving. Reacts instantly to changing surfaces for a stable, controlled and comfortable ride.
- Tuned for your vehicle. Vehicle-specific shock tuning for handling, comfort and durability.
- German engineered. The shocks are precision-engineered in Germany using premium, high-quality materials.
- Built to outlast. Most of the B6 Offroad range is fully serviceable, so it can be professionally serviced to restore performance instead of being replaced.
Pre-assembled ReadyStruts
Up front, the Bilstein B6 Offroad shocks come pre-assembled with King Springs coil springs and SuperPro strut mounts as a matched pair of ready-to-fit struts. There's no spring-and-strut dismantling before fitting, which helps cut installation time.
Ride, handling and load
- Matched to your load. The springs create the lift, so choose your front load (bull bar and winch) and rear load when you build your kit. Getting this right gives a level stance and a comfortable ride, and stops the rear sagging.
- Accessories first. Where possible, fit permanent accessories like bars, winches, drawers and canopies before the lift kit so the suspension is matched correctly from the start.
- Professional fitting. We recommend installation by a suspension technician or mechanic with wheel alignment facilities.
