Outback Armour Suspension for Holden Colorado RG (2012–2020)
Upgrade your Holden Colorado RG (2012–2020) with an Australian-engineered Outback Armour suspension kit. These kits handle corrugations, mining roads and remote touring with confidence, while still driving smoothly on the highway. Heavy-duty twin-tube shocks, matched springs and quality hardware deliver better control, comfort and load-carrying ability for real-world 4×4 use.
Why choose Outback Armour?
Australian-designed and engineered for harsh off-road conditions
Large-body shocks with high-flow pistons for consistent damping under load
Matched coil or leaf springs to suit vehicle accessories and payload
Options to suit daily drivers, tourers and heavily loaded builds
The Performance range uses robust 60 mm twin-tube shocks with high-flow internals. They deliver a balanced ride on-road and off-road without added complexity. This range suits daily-driven Colorado RGs that regularly tour, tow or travel gravel roads, without the need for external adjustments.
Digressive (DSV) Shocks
Digressive (DSV) shocks provide firm control at low shaft speeds, then soften as speeds increase. This tuning delivers:
A stable, planted feel on sealed roads and through corners
Improved compliance over corrugations and rough tracks
Better control of body roll and pitching when towing or loaded
For many owners, Digressive shocks strike the best balance between highway comfort and serious off-road performance in the Colorado RG.
Adjustable Bypass Shocks
For maximum control, Adjustable Bypass shocks use an internally adjustable bypass system with 20+ stages of damping adjustment. You can soften the ride for daily driving, then increase control for heavy loads, towing or fast off-road use.
20+ click positions for precise front and rear tuning
Easy adjustment for changing loads and terrain
Ideal for vehicles that alternate between light and heavy setups
Dial them toward comfort for everyday use, or toward control when you need the Colorado RG to stay tight and composed.
Spring & Load Options: Trail, Expedition & Expedition HD
Outback Armour matches springs and shocks to how you actually use your Holden Colorado RG (2012–2020). Rear spring options include:
Trail – Unladen / Light Load
Trail kits suit unladen or lightly loaded vehicles. They work well for daily drivers and weekend tourers carrying minimal gear. You gain improved ride quality, stability and lift height without needing a constant rear load.
Expedition – Moderate Constant Load
Expedition kits suit vehicles with a moderate constant load. Typical setups include drawer systems, fridges, small canopies, roof racks or touring gear. These kits add support and control without the firmness of the HD option.
Expedition HD – Heavy Constant Load
Expedition HD kits suit heavy, permanent loads such as steel canopies, long-range fuel tanks, full drawer systems, rear bars and spare carriers. The springs support significant constant weight, maintain correct ride height and reduce bottoming out when loaded.
If your Colorado RG rarely runs empty and works or tours full-time, Expedition HD is usually the right choice.
Expedition XHD – Extreme Constant Load
Expedition XHD kits suit very heavy constant loads and vehicles operating near GVM. This option fits Colorado RG builds with large steel canopies, full drawer and fridge systems, long-range tanks, rear bars, spare carriers, tools and work equipment.
Typical Kit Contents
Contents vary by vehicle and load rating, but most Outback Armour suspension kits include:
Front struts (assembled or unassembled) with matched front coils
Rear shocks with matched rear coils or leaf springs
Bushes, shackles, pins and U-bolts for leaf-spring setups
Additional hardware where required, such as spacers or brackets
Lift height, load ratings and part numbers vary by application. We confirm the correct setup for your Holden Colorado RG (2012–2020) during quoting.
