Outback Armour Suspension for Isuzu MU-X RF20 (2017–6/2021)
Upgrade your Isuzu MU-X RF20 (2017–6/2021) 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 better control, comfort and load-carrying ability for real-world 4×4 use.
Why choose Outback Armour?
Australian engineers design and develop every kit for demanding off-road conditions
Large-body shocks and high-flow pistons maintain 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 60 mm twin-tube shocks with high-flow internals to deliver a solid all-round ride for mixed on-road and off-road driving. These shocks suit daily-driven MU-X vehicles that regularly tour, tow or travel gravel roads, without the need for adjustment knobs or tuning.
Adjustable Bypass Shocks
For drivers who want 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 quickly firm it up for heavy loads, towing or faster off-road conditions.
20+ click positions allow precise front and rear tuning
Adjust settings to suit changing loads, terrain and driving style
Ideal for MU-X vehicles that regularly switch between unladen and fully loaded setups
In short: wind the adjusters toward comfort for a plush ride, or toward control when you need the vehicle to stay tight and composed.
Spring & Load Options: Trail, Expedition & Expedition HD
Outback Armour matches springs and shocks to how you actually use your Isuzu MU-X RF20. For the rear in particular, you can choose from the following load options:
Trail – Unladen / Light Load
Trail kits suit unladen or lightly loaded vehicles. This option works perfectly if your Isuzu MU-X serves as a daily driver or weekend tourer that only occasionally carries camping gear. You gain improved ride quality, stability and lift height without needing a constant heavy load.
Expedition – Moderate Constant Load
Expedition kits suit vehicles that carry a moderate constant load, such as rear drawers, a fridge, smaller canopy setups, medium roof racks or touring gear. These kits add support and control over factory suspension while remaining more compliant than the HD option.
Expedition HD – Heavy Constant Load
Expedition HD kits suit vehicles with heavy, permanent accessories like steel canopies, long-range fuel tanks, full drawer systems, rear bars, spare carriers and larger touring setups. The higher-rated springs support significant constant weight, keeping the vehicle at the correct ride height, maintaining stability and preventing bottoming out when loaded.
If your MU-X runs as a dedicated touring or work vehicle and rarely drives empty, Expedition HD is usually the correct choice.
