Outback Armour Suspension for Holden Trailblazer RG (2017–2020)
Upgrade your Holden Trailblazer RG (2017–2020) with an Australian-engineered Outback Armour suspension kit. These kits handle corrugations, mining roads and remote touring while still driving comfortably on the highway. Heavy-duty twin-tube shocks, matched springs and quality hardware work together to improve control, comfort and load carrying 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 specific vehicle loads and accessories
Options to suit daily drivers, tourers and heavy-load builds
Shock Options: Performance & Adjustable Bypass
Performance Range
The Performance range uses robust 60 mm twin-tube shocks with high-flow internals. This setup delivers a stable, all-round ride on and off road. It suits daily-driven 4x4s that regularly tour, tow or travel on gravel roads, without the need for adjustment knobs.
Adjustable Bypass Shocks
For maximum control, Adjustable Bypass shocks add an internally adjustable bypass system with 20+ stages of damping adjustment. You can soften the ride for town driving, then firm it up for towing, heavy loads or faster off-road work.
20+ click positions for precise front and rear tuning
Easy adjustment for changing loads, terrain and driving style
Ideal for vehicles that switch between unladen and fully loaded
In short: wind them towards comfort for a plush ride, or towards control when you need the vehicle to stay tight and composed.
Spring & Load Options: Trail, Expedition & Expedition HD
Each Outback Armour kit pairs the correct springs and shocks to match how you use your 4×4. Rear spring options include:
Trail – Unladen / Light Load
Trail kits suit unladen or lightly loaded vehicles. They work perfectly for daily drivers or weekend tourers that only carry occasional camping gear. You gain improved ride quality, stability and lift without needing constant weight.
Expedition – Moderate Constant Load
Expedition kits suit vehicles with a moderate constant load. This includes rear drawers, fridges, small canopies, medium roof racks or touring gear. They add support and control over factory suspension without the firmness of HD springs.
Expedition HD – Heavy Constant Load
Expedition HD kits handle heavy, permanent loads such as steel canopies, long-range fuel tanks, full drawer systems, rear bars and spare carriers. The higher-rate springs maintain correct ride height, improve stability and prevent bottoming out when fully loaded.
If your Trailblazer runs heavy most of the time, Expedition HD is usually the right choice.
Typical Kit Contents
Kit contents vary by vehicle and load option, 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
