Outback Armour Suspension for Isuzu MU-X RF20 (2017–06/2021)
Upgrade your Isuzu MU-X RF20 (2017–06/2021) with an Australian-engineered Outback Armour suspension kit, designed to handle corrugations, mining roads and remote touring while still driving well on the highway. These kits are built around heavy-duty twin-tube shocks, matched springs and quality hardware, delivering 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 for consistent damping under load
Matched coil or leaf springs to suit specific vehicle loads and accessories
Options for unladen daily drivers through to fully built touring vehicles
For maximum tuning flexibility, Adjustable Bypass shocks feature an internally adjustable bypass system with 20+ stages of damping adjustment. You can soften the ride for daily driving, then firm it up for towing, heavy loads or faster off-road work.
20+ click positions for precise front and rear tuning
Adjust damping to suit changing loads and terrain
Ideal for MU-X builds that regularly alternate between unladen and fully loaded use
Set them towards comfort for a plush touring ride, or towards control when stability and load support are the priority.
Spring & Load Options: Trail, Expedition, Expedition HD & XHD
Each Outback Armour kit is matched to how your Isuzu MU-X RF20 is actually used. Rear spring selection is especially important, with options including:
Expedition – Moderate Constant Load
Expedition kits are tuned for moderate, constant touring loads such as drawer systems, fridge setups, roof racks or regular towing. This option provides added support and stability while maintaining good ride comfort.
Expedition HD – Heavy Constant Load
Expedition HD kits are designed for heavily equipped MU-X builds running steel rear bars, spare wheel carriers, long-range fuel tanks, full drawer systems and regular touring weight. These springs maintain correct ride height and control under sustained load.
