Choose your rear coil spring rate based on the constant weight you carry, not just occasional load. Vehicles fitted with a bull bar, winch, drawers, fridge slide or long-range fuel tank need a firmer rear rate to keep the MU-X sitting level and avoid bottoming out over dips. Common accessories that shift spring selection include bull bars and winches up front, and drawer systems, dual batteries or camper trailer tow ball weight at the rear.
This kit is best fitted by an experienced 4WD suspension installer or a competent DIY mechanic with the correct spring compressors and torque specs. A wheel alignment is mandatory after fitting to correct camber and toe at the new ride height and protect tyre wear. Allow a 500km settling period for the new coil springs to reach their working height before final alignment if your installer recommends a two-stage check. Many MU-X owners pair this kit with upgraded control arms to correct front geometry and CV angles at the 2" lift height.
Toughdog has supplied Australian 4WD and touring vehicle owners with locally tuned suspension for decades, building foam cell shocks and coil springs to suit Australian roads and payloads rather than a single overseas spec. Every kit carries a manufacturer warranty and is supported by our team for fitment questions before and after purchase. Tradespeople, grey nomads and weekend tourers all run Toughdog gear on the MU-X for its balance of comfort and load-carrying ability — view the full Toughdog range.
This kit suits MU-X owners who tow, carry canopy or drawer weight, or fit a bull bar and winch and need the front and rear ride height restored. It's a solid fit for tradespeople running tools daily and tourers loading up for extended trips. If your accessory load is heavier again or you need adjustable load-levelling on demand, our airbag suspension range can be added to the rear coils for extra support.

Yes, this Tough Dog kit is built specifically for the Isuzu MU-X Gen 1 (UC) sold from 2014 through to June 2021, covering LS-M, LS-U and LS-T trims. It is not designed for the facelifted MU-X Gen 2 (07/2021 onward), which uses a different platform. If you're unsure which generation you have, check your build date on the compliance plate or use our parts finder for the Isuzu MU-X. Our team can confirm fitment from your VIN or build plate before you order.
This kit provides a 2" lift front and rear on the Isuzu MU-X Gen 1, achieved through raised coil springs paired with matched-length foam cell shock absorbers. The 2" figure is measured at the standard load setting; actual ride height can vary slightly depending on the spring rate selected and vehicle accessory weight. Front and rear lift is even in this kit, so the MU-X sits level rather than nose-down or rear-high. Our team can talk you through expected ride height for your specific accessory setup.
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 foam cell front shock absorbers, 2 x foam cell rear shock absorbers, 2 x raised front coil springs and 2 x raised rear coil springs. Mounting hardware, spring seats and shock bushes are included, along with fitment instructions and Toughdog warranty documentation. Upper control arms are not included and are sold separately if you need corrected front geometry at the lifted height. See the full kit contents list above for exact quantities.
Yes, this kit is a common choice for MU-X owners who tow, thanks to the heavy-duty rear coil springs available in different constant load ratings. Selecting a firmer rear spring rate to match your tow ball weight and payload keeps the rear from sagging under a loaded trailer or caravan. The foam cell rear shocks also help control body movement when towing on corrugated or unsealed roads. Tell our team your typical tow ball weight and we can help you pick the right spring rate.
At a 2" lift height, most MU-X owners get acceptable CV joint and camber angles without changing control arms, but upgraded units can improve geometry and travel further. If you're running larger accessories, bigger tyres, or want the geometry corrected as close to factory as possible, we recommend adding upgraded control arms. Our team can advise based on your exact combination of lift, tyre size and driving use. Control arms are sold separately from this kit.
Yes, a wheel alignment is mandatory after installing this kit. Raising the MU-X by 2" changes camber and toe settings, and skipping alignment leads to uneven tyre wear and can affect handling. We recommend an alignment straight after fitment, and a second check after a 500km settling period once the new coil springs have reached their working height. Book your alignment with a shop familiar with lifted 4WDs for best results.
Yes, Tough Dog offers this kit with different constant load rear coil spring options to suit your accessory and touring weight. If you run a bull bar, winch, drawers or tow a camper trailer regularly, a firmer rear spring rate keeps the MU-X sitting level under that constant load. Let our team know your typical accessory fit-out and towing weight and we'll recommend the right spring rate before you order. Front spring rates are generally matched to accessory weight up front, such as a bull bar and winch.
A 2" lift on the MU-X typically creates clearance for a modest tyre size increase over stock, though exact clearance depends on wheel offset and width. Most owners running this kit fit up to a 265/70R17 or similar without major rubbing, but we always recommend confirming your specific wheel and tyre combination with our team. Guards and mudflaps may need trimming for larger tyre and wheel packages. Contact us with your intended tyre size before purchase to confirm clearance.
This kit is covered by Tough Dog's manufacturer warranty, which applies to manufacturing defects in the shocks and springs when fitted and used as intended. Warranty documentation is included with the kit and our team can assist with any warranty claim through 4WD Suspension. Keep your proof of purchase and fitment date for warranty reference. Contact our team directly if you have any warranty questions after installation.
Yes, this kit is designed to balance daily on-road comfort with off-road and touring capability, not just track or trail use. The foam cell shocks control body movement on the highway while the raised coil springs maintain a comfortable ride at standard load. Owners commuting daily and touring on weekends both run this kit on the MU-X without needing a stiffer, off-road-only setup. Selecting the correct spring rate for your typical daily load helps keep the ride comfortable rather than firm.
