The Dobinsons Nitro Gas 2" Lift Kit suits the Isuzu MU-X UC series (2013-2021) and pairs twin-tube nitro gas shocks with vehicle-specific coil springs for a genuine 2" lift front and rear. Big-bore 35mm front and 32mm rear shock bodies use Fuchs oil and NOK seals for consistent damping under load, while the upgraded coil springs handle bull bars, drawer systems and touring accessories without a harsh ride. Pair it with upgraded control arms for corrected geometry at ride height. Dispatched from Australian stock with manufacturer warranty and fitment support from our team.

Spring rates should be matched to your constant accessory load — the weight permanently fitted to the vehicle, not occasional gear. Common front loads include bull bars, winches and long-range fuel tanks, while rear loads include drawer systems, dual batteries, water tanks and canopies. Occasional loads such as camping gear or caravan towing are better managed with airbag suspension rather than stiffer springs.
Installation should be carried out by a qualified mechanic or experienced 4WD suspension fitter given the strut and coil spring assembly involved. A full wheel alignment is required after fitting to correct steering geometry and ensure even tyre wear. Allow a 500km break-in period for the shocks and springs to settle, avoiding harsh off-road use during this time. Depending on your MU-X model and use, pairing this kit with upgraded control arms can further correct castor angle and reduce upper control arm wear at the 2" lift height.
Dobinsons Spring & Suspension has manufactured suspension products in Australia for decades, with in-house engineers designing and testing kits on Australian roads and tracks. Every Nitro Gas kit uses the same Fuchs oil, NOK seals and hardened rod specification across the range, backed by manufacturer warranty. You can view the full Dobinsons range to compare kits across other 4WD platforms.
This kit suits MU-X owners who tour with roof-top tents and camping gear, tradespeople with permanently fitted tool storage, and caravan or camper trailer owners wanting stable, level towing. If your load varies significantly trip to trip, consider adding airbag suspension for on-demand adjustment alongside this kit.

Yes, this Dobinsons Nitro Gas 2" Lift Kit is designed specifically for the Isuzu MU-X UC series built between 2013 and 2021, across all variants. It is not a universal kit — the struts, shocks and coil springs use MU-X-specific valving and spring rates. If you are unsure of your build date or variant, our team can confirm fitment before you order. You can also check compatible parts through our MU-X parts finder.
This kit provides a 2" lift front and rear on the Isuzu MU-X, achieved through raised coil springs and matching Nitro Gas struts and shocks. The lift is even front to rear, which keeps factory driveline and brake line angles within a safe range. This increases ground clearance for underbody protection and allows fitment of larger diameter tyres. Actual ride height can vary slightly depending on accessory load and spring rate selected.
Please note that all assembled struts are dispatched at a height based on our experience and the manufacturer’s specifications for the advertised lift. Coil springs and leaf springs are also manufactured according to the advertised height and constant-load rating. Actual vehicle height may vary depending on the vehicle and the weight of fitted accessories. Further adjustment may therefore be required after installation. The installer may use coil spacers or adjust the struts at their discretion to achieve the desired height. We are not responsible for vehicle-specific height variations or any additional adjustments required after installation.
The kit includes 2 x Dobinsons Nitro Gas front struts, 2 x Nitro Gas rear shock absorbers, and matching front and rear raised coil springs. Mounting hardware, bushes and fitting instructions are included for a complete front and rear installation. Upper control arms are not included and are sold separately if required. See the full kit contents list on this page for exact components.
Yes, the upgraded coil springs and big-bore shocks improve load handling and reduce rear sag compared to factory suspension when towing. Spring rates should be selected based on your constant accessory load, not the occasional weight of a caravan or trailer. For variable towing loads, we recommend adding airbag suspension to maintain level ride height on demand. Our team can help you match the right spring rate to your towing setup.
Control arm upgrades are not mandatory but are recommended at 2" of lift to correct castor angle and reduce upper ball joint wear over time. Factory upper control arms can bind at increased ride height, so upgraded control arms restore proper geometry and improve wheel articulation. Whether you need them depends on your driving style and how much off-road articulation you use. Our fitment team can advise based on your specific MU-X model year.
Yes, a full wheel alignment is mandatory after installing this lift kit. Raising ride height changes camber, caster and toe settings, and an alignment ensures even tyre wear and safe steering response. This should be booked immediately after fitment, before extended driving. Skipping alignment can accelerate tyre wear and affect handling.
Dobinsons offers spring rate options for the MU-X based on your constant accessory load, such as bull bars, winches or drawer systems fitted permanently to the vehicle. Selecting a rate should be based on this constant load, not occasional camping gear or towing weight. Our team can help you calculate your accessory load and recommend the correct front and rear spring rate. Overly stiff springs for occasional loads will make the ride harsher without benefit.
The 2" lift height typically allows clearance for larger diameter tyres than the MU-X's factory setup, though exact clearance depends on tyre width, offset and whether flares are fitted. We recommend checking your intended tyre size with our team before ordering to confirm clearance at full steering lock and suspension compression. Larger tyres may also require checking speedometer calibration.
This Dobinsons Nitro Gas Lift Kit is covered by manufacturer warranty against defects in materials and workmanship. Warranty terms apply to the shocks and coil springs as supplied, and cover does not extend to damage from incorrect fitment or off-road misuse. Contact our team for the specific warranty period and claims process. We handle warranty support locally from our Australian warehouse.
Yes, the Nitro Gas valving is tuned to balance daily on-road comfort with load-carrying capability, so it is not a harsh off-road-only setup. Natural rubber bushings reduce noise and vibration through the cabin compared to some aftermarket alternatives. Many MU-X owners run this kit as their daily driver while retaining improved capability for weekend touring. A 500km break-in period applies before the ride settles to its final feel.
