Description

Outback Armour Suspension for Isuzu MU-X RJ21 (07/2021+)

Upgrade your Isuzu MU-X RJ21 (07/2021+) 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, giving you 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 heavy touring rigs

Shock Options: Performance, Digressive & Adjustable Bypass

Performance Range

The Performance range uses robust 60 mm twin-tube shocks with high-flow internals, giving a solid all-round ride for mixed on-road and off-road use. They’re a great option for daily-driven 4x4s that see regular touring, towing and gravel roads without needing fine-tuning knobs.

Adjustable Bypass Shocks

For those who want maximum control, Adjustable Bypass shocks add an internally-adjustable bypass system with 20+ stages of damping adjustment. You can dial the shocks softer for comfort around town, then firm them up for heavy loads, towing or faster off-road driving.

• 20+ click positions for precise tuning front and rear
• Adjust for changing loads, terrain and driving style
• Ideal for vehicles that regularly swap 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 is built around matched springs and shocks to suit how your Isuzu MU-X RJ21 (07/2021+) is actually used. For the rear in particular, you can choose from:

Trail – Unladen / Light Load

Trail kits are aimed at unladen or lightly-laden vehicles – perfect if your Isuzu MU-X RJ21 (07/2021+) is mainly a daily driver or weekend tourer with occasional camping gear in the back. You get improved ride, stability and lift height without needing a heavy constant load in the vehicle.

Expedition – Moderate Constant Load

Expedition kits are matched to vehicles carrying a moderate constant load – think rear drawers, fridge, small canopy set-ups, medium roof rack or touring gear. They provide extra support and control over stock suspension without going as firm as the HD option.

Expedition HD – Heavy Constant Load

Expedition HD kits are built for heavy, permanent loads – steel canopies, long-range tanks, full drawer systems, rear bars, spare carriers and bigger touring set-ups. The springs are rated for significant constant weight so the vehicle sits at the correct height, remains stable and avoids bottoming out when loaded.

If your 4×4 is set up as a serious touring or work vehicle and rarely runs empty, Expedition HD is generally the correct choice.

Typical Kit Contents

Exact contents vary by vehicle and load option, but most Outback Armour suspension kits will include:

• Front struts (assembled or unassembled) and matched front coils
• Rear shocks and matched rear coils or leaf springs
• Required bushes, shackles, pins and u-bolts for leaf-spring setups
• Additional hardware where required (e.g. spacers, brackets, link rods)

Lift height, load ratings and part numbers are specific to each vehicle; we’ll confirm these for your Isuzu MU-X RJ21 (07/2021+) when quoting.
