The Tough Dog 2" Lift Kit is built specifically for the Isuzu D-Max Series 3 (2020-ON), using nitrogen gas front struts and multi-stage rear leaf packs engineered in Australia for corrugated tracks and long-distance towing. This 4WD lift kit adds 2" of ground clearance while spring rates are matched to your accessory load, from bull bar and winch to canopy and tray. Every kit ships from Australian stock with a manufacturer warranty and fitment guidance from our suspension team. Expect a firmer, more planted ride under load without the harsh feedback of stock leaf springs.

Choose your rear leaf spring rate based on the constant weight carried, not just the maximum you'll ever load. Heavier rates suit tourers running a fitted canopy, dual battery setup, water tank or caravan tow ball weight, while lighter rates suit a bare tray or occasional loads. Front spring choice should account for a steel bull bar, winch and driving lights, which add sustained weight to the front axle.
This kit is best fitted by an experienced 4WD suspension installer or a competent DIY mechanic with the correct spring compressors and torque specs on hand. Wheel alignment is mandatory once the kit is installed, as the 2" lift changes camber and caster angles. Allow a 500km bedding-in period before final alignment and torque checks. For vehicles running a bull bar or heavier front accessories, pairing this kit with upgraded control arm upgrades helps correct front geometry at the new ride height.
Tough Dog has built suspension for the Australian 4WD market for decades, tuning shocks and springs specifically for local roads, loads and climate rather than adapting overseas parts. Kits are backed by a manufacturer warranty and are used by tourers and tradespeople who need a suspension setup that handles daily load-carrying as well as weekend touring. You can view the full Toughdog range to compare shock and spring options across other applications.
This kit suits D-Max owners running a canopy, tool boxes and daily trade loads, as well as tourers towing a camper or caravan who need consistent rear ride height. If you're carrying variable loads rather than a constant weight, it's worth comparing this leaf spring setup against airbag suspension for adjustable load support.

This kit is built specifically for the Isuzu D-Max Series 3 (RG), covering the 2020-ON model range with the 3.0L turbo diesel engine. It is not designed for earlier D-Max generations, which use different front strut and leaf spring mounting. If you're unsure which series you have, our team can confirm fitment against your VIN or build plate before you order.
This Tough Dog kit provides a 2" lift at both the front and rear of the D-Max Series 3. The front lift comes from raised coil springs paired with nitrogen gas struts, while the rear lift comes from the multi-stage leaf spring pack. Actual ride height can vary slightly depending on the spring rate selected and vehicle load.
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 nitrogen gas struts with raised coil springs, rear multi-stage leaf spring packs, matched rear shock absorbers, U-bolt kits, greasable shackle and pin kits, bump stops and mounting hardware. Upper control arms are not included and are sold separately if your accessory load requires corrected front geometry. A full itemised list is shown in the kit contents section above.
Yes, the rear multi-stage leaf springs are designed with towing and constant accessory loads in mind. Selecting a firmer rear spring rate at order time helps maintain rear ride height with a caravan or camper on the tow ball. Pairing this kit with the correct spring rate for your setup keeps the rear from sagging under sustained tow weight.
Control arms aren't included in this kit, but they're worth considering if you're running heavier front accessories like a steel bull bar and winch. Upgraded control arms help correct front geometry and reduce strain on bushes at the new 2" ride height. Our team can advise whether your specific accessory setup needs this upgrade.
Yes, wheel alignment is mandatory after installing this kit. The 2" lift changes front camber and caster angles, and correct alignment protects tyre wear and steering feel. We recommend a 500km bedding-in period before the final alignment check, allowing the new springs and bushes to settle.
Yes, Tough Dog offers multiple front and rear spring rate options for this kit. Rate selection should be based on your constant accessory load, such as a bull bar, winch, canopy or water tank, rather than your maximum occasional load. Our team can help you match spring rates to your specific D-Max setup before dispatch.
The 2" lift from this kit typically provides enough clearance for a modest tyre size increase over standard, depending on your wheel offset and body clearance. Exact tyre fitment depends on width and rim combination, so it's worth checking with our team if you're planning a specific tyre and wheel package. Some setups may still require minor trimming for full-lock clearance.
This kit is backed by a manufacturer warranty from Tough Dog, covering defects in materials and workmanship under normal use. Warranty terms apply to both the front struts and rear leaf spring and shock components. Contact our team for the specific warranty period and claims process for your order.
Yes, this kit is designed to balance daily on-road comfort with load-carrying and towing performance, not just off-road use. The front nitrogen gas struts and correctly matched rear spring rate keep the ride settled at highway speed when the vehicle is running its intended load. Choosing a spring rate suited to your everyday accessory weight, rather than an overly firm rate, keeps the daily ride comfortable.
