The Toughdog Lift Kit for the Isuzu MU-X (2013-2021) delivers a genuine 2" lift front and rear, using complete strut assemblies up front and raised coil springs at the rear, matched to foam cell shock absorbers on all four corners. Constant load spring options to 300kg let you carry a canopy, bullbar or touring gear without sag, while foam cell damping controls rebound on corrugations and the highway alike. Toughdog backs the kit with a 2-year shock warranty, and it pairs well with upgraded control arms for corrected geometry at ride height. This complete 4WD lift kit is in stock in Australia now, with fitment support from our suspension specialists.

Choose your rear spring rate based on what stays fitted to the vehicle day-to-day, not just what you carry occasionally. A standard-rate spring suits an unladen or lightly accessorised MU-X, while a 300kg constant load rate suits a fitted canopy, drawer system, dual battery tray, or a permanently mounted camper trailer hitch load. Common accessories that shift your spring choice include steel bullbars, winches, long-range fuel tanks, roof racks with rooftop tents, and rear drawer systems with fridge slides.
Fitment is best handled by an experienced 4WD suspension installer or a mechanically confident DIYer with a hoist and spring compressor, given the front strut assembly replacement and torque specs involved. Wheel alignment is mandatory after fitting — the increased ride height changes camber and caster, and skipping this step accelerates tyre wear. Allow a 500km settling period for the springs to seat and the ride height to stabilise before fine-tuning alignment if needed. For MU-X owners running the kit at full load, pairing it with upgraded control arm upgrades corrects front geometry and restores factory-like handling at the new ride height.
Toughdog has supplied Australian 4WD owners with locally-focused suspension engineering for decades, with foam cell shock technology developed for our roads and load conditions. Every kit carries a manufacturer warranty and is dispatched from Australian stock, backed by our team's fitment guidance for the MU-X specifically. Tradespeople, remote-area tourers and weekend campers all run Toughdog gear — view the full Toughdog range to compare options across your vehicle.
This kit suits MU-X owners who tow a camper or boat, tradies carrying tool storage and equipment daily, and touring families running a rooftop tent or drawer system. If your accessory load is heavier again — think permanent canopy plus long-range tank plus winch — talk to us about airbag suspension to add load-levelling on top of the spring upgrade.

Yes, this Toughdog kit is built specifically for the Isuzu MU-X across LS-M, LS-U and LS-T grades from 2013 to 2021. It suits the 3.0L 4JJ1-TCX turbo diesel model in both 4x2 and 4x4 configurations. If you're unsure of your exact build date or series, check your compliance plate or use our parts finder for the MU-X before ordering.
This kit provides a 2" lift at the front and 2" at the rear over standard ride height. The front lift comes from the strut assembly and the rear lift from the raised coil springs. Actual ride height gain can vary slightly depending on your vehicle's current load and spring wear.
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.
You get 2 x front foam cell strut assemblies, 2 x rear foam cell shock absorbers, and 2 x raised rear coil springs, plus mounting hardware and fitment documentation. Upper control arms are not included and are sold separately if you need them for alignment correction. See the full kit contents list on this page for exact quantities.
Yes, the constant load rear spring options up to 300kg are designed for vehicles that tow regularly or carry fitted accessories. Choosing the correct spring rate for your typical tow ball download keeps the rear from sagging under a loaded camper or trailer. Talk to our team about your specific tow setup so we recommend the right rate.
At a 2" lift height, factory upper control arms on the MU-X can run out of correct camber and caster range, which is why we recommend upgraded control arms alongside this kit. It's not always mandatory but it improves alignment accuracy and CV joint angles at height. Our fitment team can advise whether your intended use warrants the upgrade.
Yes, wheel alignment is mandatory after installing this kit. The 2" lift changes front camber and caster angles, and skipping alignment leads to uneven tyre wear and altered steering feel. We recommend a professional alignment immediately after fitment and again after the 500km settling period.
Yes, the rear coil springs are available in standard and constant load rated options up to 300kg to suit your typical accessory and towing load. Selecting the right rate depends on what stays fitted to your MU-X day-to-day, such as a canopy or drawer system. Our team can help match the spring rate to your setup before you order.
The 2" lift front and rear typically creates enough clearance for a modest tyre size increase over standard, though exact clearance depends on your wheel offset and width. We recommend confirming your intended tyre size with our team before purchase to avoid rubbing on guards or suspension components. Wheel alignment and correct control arm geometry also help maximise usable clearance.
Toughdog backs this kit with a manufacturer warranty covering the front struts, rear shocks and coil springs against manufacturing defects. Warranty terms are documented in the paperwork supplied with your kit. If you have a warranty query on a fitted kit, our team can help liaise with Toughdog directly.
Yes, the foam cell shock valving is tuned to keep ride quality comfortable for daily commuting while still handling the extra height and load capacity. Many MU-X owners run this kit as their everyday setup and switch spring rates only if their accessory load changes significantly. Fitting correct control arms helps keep steering and handling feeling close to standard at the new ride height.
