Choose your coil and leaf spring rate based on the constant weight sitting on the vehicle day to day, not the occasional maximum load. Common accessories that add constant load include steel bullbars, winches, bull bar-mounted spotlights, rear drawer systems, dual battery trays, canopies, tool boxes and van tow weight. If you regularly carry more than 150-200kg of fitted accessories and touring gear, step up to the Medium or Heavy rated coil and leaf option rather than staying on Standard.
This kit is best fitted by an experienced 4WD workshop or a competent DIY installer with the right tools, given the strut and leaf spring removal involved. Wheel alignment is mandatory after fitting to bring camber, caster and toe back into spec at the new ride height. Allow a 500km bed-in period for springs and bushes to settle before final alignment if your installer recommends it. Pairing this kit with upgraded control arms helps correct front suspension geometry and CV angles on MU-X builds with a 2" or greater lift.
Tough Dog has supplied 4WD suspension to the Australian market for decades, with kits developed and valved locally rather than adapted from overseas passenger-car tuning. This kit is backed by manufacturer warranty and is dispatched from Australian stock with fitment support from our team on hand for any vehicle-specific questions. Tradespeople, tourers and van owners running MU-X utes and wagons commonly choose Tough Dog for this reason — you can view the full Toughdog range to compare shock and spring options.
This kit suits MU-X owners fitting bullbars, winches and drawer systems who need the coil and leaf rate to match, and tourers wanting a 2" lift for tyre clearance and articulation on tracks. Tradies and van-towers who need constant rear load support will benefit from the Heavy-rated leaf option. If your accessory load varies trip to trip, also look at our airbag suspension options to fine-tune rear support on demand.

This Tough Dog kit is built for the Isuzu MU-X UC series from 2014 through to June 2021, covering both RWD and 4WD variants with the 3.0L turbo diesel engine. If your MU-X falls outside this build range, including the post-2021 facelift model, the shock and spring specs differ and you'll need the current-model kit instead. Our team can confirm your exact build date and series from your compliance plate or VIN before you order. Use our MU-X parts finder to double check compatible parts for your specific vehicle.
This kit provides a 2" lift front and rear over standard ride height, using raised coil springs up front and heavy-duty leaf springs at the rear. The exact lift achieved on your vehicle can vary slightly depending on the coil or leaf load rating fitted and any accessories already carried. A 2" lift is enough to clear larger touring tyres and improve approach and departure angles without requiring extended brake lines on most MU-X builds. Our team can talk you through expected ride height for your chosen load rating.
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 front foam cell strut assemblies, rear foam cell shock absorbers, raised front coil springs and heavy-duty rear leaf springs, plus the U-bolts, spring bushes and shackle bushes needed for the rear leaf spring fitment. Full fitting hardware and instructions are included. Upper control arms are not part of this kit and are sold separately if your build needs them. See the full kit contents list on this page for exact quantities.
Yes, the rear leaf springs are available in Heavy Duty load ratings specifically to support constant towball download and van or trailer weight. Selecting the correct rear rating for your typical towing load keeps the MU-X sitting level rather than sagging under the tow ball. For variable towing loads, pairing this kit with airbag suspension gives adjustable extra support on demand. Speak to our team about your van or trailer weight before selecting a spring rate.
At a 2" lift height, many MU-X owners run this kit on factory control arms without issue, but upgraded control arms improve camber and CV joint angle correction at height. If you're maximising articulation or running larger diameter tyres, control arm upgrades are worth adding at the same time as the lift kit install. Our fitment team can advise whether your specific use case needs them.
Yes, wheel alignment is mandatory after fitting this kit. Raising the MU-X changes camber, caster and toe settings, and correct alignment protects tyre wear and keeps steering feel consistent. We recommend an alignment straight after install, with a further check after the 500km bed-in period once springs and bushes have settled.
Yes, both the front coil springs and rear leaf springs in this kit are available in Standard, Medium (0-300kg) and Heavy (300kg+) constant load ratings. Choose your rating based on the accessories and gear you carry day to day, such as a bullbar, winch, drawers or canopy, not just occasional maximum loads. Our team can help match the right rating to your build before you order.
A 2" lift on the MU-X typically clears a moderate increase in tyre diameter over stock, improving clearance for common touring tyre sizes. Actual clearance depends on your wheel offset and width as well as the tyre size chosen. Our team can advise on suitable tyre and wheel combinations once you know your target lift height and load rating.
This kit is backed by Tough Dog's manufacturer warranty, covering shocks and springs against manufacturing defects when fitted and used as intended. Warranty terms are handled through 4WD Suspension as your Australian point of contact, so you're not dealing with an overseas supplier directly. Keep your proof of purchase and fitment records for any warranty claim.
Yes, the foam cell shock and raised spring combination is designed to retain comfortable on-road ride quality at the correct load rating, not just off-road performance. Selecting a Standard load rating if you don't carry heavy accessories keeps the ride closer to factory comfort for daily commuting. Choosing a Heavy rating for a mostly-unladen MU-X will feel firmer, so match the rating to your actual daily load, not just your occasional touring setup.
