The Dobinsons IMS Lift Kit suits the Isuzu MU-X UCS40 (08/2020-On) and combines monotube shock absorbers with vehicle-specific 2" raised coil springs front and rear. The monotube design uses an internal floating piston to separate oil and gas, cutting fade on corrugations and giving more consistent damping than a twin-tube shock. The 2" lift adds clearance for larger tyres and pairs well with aftermarket control arms for corrected geometry at height — check all suspension parts for the MU-X to confirm fitment. Backed by Dobinsons warranty, dispatched from Australian stock with fitment support from our team.

Choose your front and rear spring rate based on the constant weight you carry, not just peak load. Common front accessories that add weight include bull bars, winches and driving light bars, while rear-loaded accessories include canopies, drawer systems, water tanks and touring gear. If you're running a heavier bull bar or winch up front, or towing a van with a loaded canopy, talk to our team about a firmer spring rate before you order — swapping springs after fitment adds cost and downtime.
This kit is best fitted by an experienced 4WD suspension installer or a qualified workshop, given the coil spring compression and shock mounting involved. Wheel alignment is mandatory after fitting to bring camber, caster and toe back within spec at the new ride height. Allow a 500km settling period for the coil springs to seat before your final alignment if your installer recommends it. Pair the kit with control arm upgrades to correct CV angles and extend travel at the new ride height.
Dobinsons has been building 4WD suspension in Australia for decades, with IMS shocks designed and valved for local roads and conditions. Every kit is backed by a Dobinsons manufacturer warranty, and the MU-X-specific springs and shocks in this kit are matched as a set rather than sold as generic parts. Tourers and tradespeople across Australia run Dobinsons gear for daily driving, towing and remote travel — view the full Dobinsons range to compare kits for other vehicles.
This kit suits MU-X owners who tow a van or trailer, carry bar work and drawers, or want extra tyre clearance for touring without an aggressive stance. If you're running near-constant heavy rear loads such as a caravan hitch weight or a loaded canopy, also look at airbag suspension to add load-levelling support on top of the coil upgrade. It's also a straightforward upgrade for daily drivers wanting sharper damping control without losing on-road comfort.
This Dobinsons IMS Lift Kit is in stock in Australia for fast dispatch, with our team on hand to confirm fitment for your MU-X before you order. Browse our full lift kit range to compare other options, or get in touch for spring rate advice.

This Dobinsons IMS Lift Kit is built specifically for the Isuzu MU-X UCS40 built from 08/2020 onward. It is not a generic fit for earlier MU-X models (UCS20) which use a different suspension platform. If you're unsure which series you have, check your compliance plate or use our parts finder for the MU-X. Our team can confirm fitment against your VIN before you order.
This kit delivers a 2" lift front and rear using Dobinsons vehicle-specific raised coil springs paired with IMS monotube shocks. The lift is consistent front to rear, so ride height and stance stay level once fitted and aligned. This is enough to clear a larger tyre and add ground clearance without pushing driveline or CV angles to an extreme. Final ride height can vary slightly with vehicle load and spring rate chosen.
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 IMS monotube front shocks, 2 x IMS monotube rear shocks, and matched 2" raised coil springs for both the front and rear. Mounting hardware, bushes and fitting instructions are included. Upper control arms and diff drop kits are not included and are sold separately if your setup requires them. Full contents are listed in the kit includes section above.
Yes, the MU-X IMS kit is a common choice for owners towing a van, box trailer or camper. The vehicle-specific spring rates can be matched to your typical accessory and tow ball load, and the monotube shocks maintain consistent damping under sustained load on longer trips. If you're carrying near-constant heavy rear weight, we'd also suggest looking at airbag suspension as a load-levelling add-on. Talk to our team about your tow setup before ordering so we can recommend the right spring rate.
A 2" lift on the MU-X can be run on factory upper control arms in many cases, but upgraded control arms improve CV joint and camber angles at the new ride height. This becomes more important if you're also running larger tyres or doing regular off-road driving. We stock upgraded control arms designed to work alongside this lift kit. Speak with our team if you want a recommendation based on your driving.
Yes, wheel alignment is mandatory after installing this kit. Changing ride height alters camber, caster and toe, and running the vehicle without a fresh alignment causes uneven tyre wear and can affect handling. We recommend an alignment straight after fitment, and again after a short settling period once the coil springs have seated. This is a standard step with any coil spring lift kit, not unique to this product.
Dobinsons offers this IMS kit with coil springs matched to different constant load requirements for the MU-X. If you're running heavier bar work, a winch, or a loaded canopy and drawers, a firmer spring rate keeps the ride height and handling correct rather than sagging under load. Tell us your typical accessory and touring load when ordering so we can point you to the right spring option. Getting this right up front avoids having to swap springs later.
The 2" lift on this kit is commonly used to clear a larger diameter tyre than the factory-fitted size on the MU-X. Actual clearance depends on tyre width, wheel offset and whether you've also fitted flares or trimmed guards. We can advise on a suitable tyre size range once we know your intended wheel and tyre combination. Larger tyres may also warrant the control arm and alignment considerations covered above.
This kit is covered by the Dobinsons manufacturer warranty, which applies to the shocks and springs supplied in the kit. Warranty terms are handled through 4WD Suspension as your Australian supplier, with our team assisting on any claims. Keep your proof of purchase and fitment date for warranty reference. Contact us directly if you have any warranty questions before or after fitting.
Yes, this kit is designed to suit MU-X owners who drive daily as well as tow or tour. The monotube shock design gives controlled damping on sealed roads without the harsh ride sometimes associated with heavier off-road-focused setups. Selecting the correct spring rate for your typical load is the main factor in keeping the daily ride comfortable. Most MU-X owners running this kit use it for a mix of commuting, towing and occasional off-road use.
