Outback Armour Suspension for Isuzu D-Max RG1 (10/2021+)
Upgrade your Isuzu D-Max RG1 (10/2021+) with an Australian-engineered Outback Armour suspension kit that confidently handles corrugations, mining roads and remote touring while still driving comfortably on the highway. Outback Armour builds these kits around heavy-duty twin-tube shocks, matched springs and quality hardware to deliver improved control, comfort and load carrying for real-world 4×4 use.
Why choose Outback Armour?
Designed and engineered in Australia for demanding off-road conditions
Large-body shocks and high-flow pistons deliver consistent damping under load
Matched coil or leaf springs suit specific vehicle loads and accessories
Options available for unladen daily drivers through to heavy touring rigs
The Performance range uses robust 60Â mm twin-tube shocks with high-flow internals to provide a solid all-round ride for mixed on-road and off-road use. These shocks suit daily-driven 4x4s that regularly tour, tow and travel gravel roads, without the need for external adjustment.
Digressive (DSV) Shocks
Digressive (DSV) shocks deliver firmer control at low shaft speeds, then progressively soften as shock speed increases. In practice, this tuning provides:
A planted, stable feel on bitumen and through corners
A smoother, more compliant response over corrugations and rough tracks
Improved control of body roll and pitching when loaded or towing
If you want a strong balance between highway comfort and serious off-road capability, the Digressive option usually hits the sweet spot.
Adjustable Bypass Shocks
For drivers who want maximum control, Adjustable Bypass shocks feature an internally adjustable bypass system with 20+ stages of damping adjustment. You can soften the shocks for everyday comfort, then firm them up for heavy loads, towing or faster off-road driving.
20+ click positions allow precise front and rear tuning
Adjust settings to suit changing loads, terrain and driving style
Ideal for vehicles that frequently 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
Outback Armour designs each suspension kit around matched springs and shocks to suit how you actually use your 4×4. For the rear, you can choose from the following load options:
Trail – Unladen / Light Load
Trail kits suit unladen or lightly loaded vehicles. They work perfectly if your Isuzu D-Max RG1 (10/2021+) mainly serves as a daily driver or weekend tourer with occasional camping gear. You gain improved ride quality, stability and lift height without relying on a constant heavy load.
Expedition – Moderate Constant Load
Expedition kits suit vehicles carrying a moderate constant load, such as rear drawers, a fridge, small canopy setups, medium roof racks or touring gear. They add support and control over factory suspension without stepping up to the firmness of the HD option.
Expedition HD – Heavy Constant Load
Expedition HD kits handle heavy, permanent loads including steel canopies, long-range fuel tanks, full drawer systems, rear bars, spare carriers and larger touring setups. These springs support significant constant weight so the vehicle sits at the correct height, stays stable and resists bottoming out when loaded.
If your 4×4 serves as a serious touring or work vehicle and rarely runs empty, Expedition HD usually provides the correct setup.
Expedition XHD – Extreme Constant Load
Expedition XHD kits target very heavy, constant loads where the vehicle remains permanently built and regularly operates at or near GVM. This option suits Isuzu D-Max RG1 (10/2021+) builds with large steel canopies, full drawer and fridge systems, long-range fuel tanks, rear bars with spare carriers, plus tools and work equipment.
Expedition XXHD – Maximum Constant Load / GVM Builds
Expedition XXHD kits represent the heaviest-duty spring option in the Outback Armour range. They suit vehicles carrying maximum permanent loads and operating at or very close to GVM full-time. This setup works best for Isuzu D-Max RG1 (10/2021+) builds with extreme rear weight, such as fully equipped steel canopies, long-range fuel tanks, full drawer and fridge systems, rear bars with dual spares, tools and work equipment.
XXHD springs maintain correct ride height, stability and suspension travel under constant extreme load, making them ideal for hard-working tourers, trade vehicles and remote-area rigs that rarely, if ever, run empty.
