The Tough Dog complete lift kit for the Isuzu D-Max 2012-2020 pairs foam cell front struts with progressive rate coil springs and nitrogen gas rear shocks matched to a multi-leaf rear pack, lifting the vehicle 2" front and rear. This suspension lift kit adds ground clearance for larger tyres and firms up load carrying and towing stability without making the ride harsh on the black top. Every component is sized to work as a matched set front and rear, so damping and geometry stay balanced at the new ride height. Toughdog backs the kit with a manufacturer warranty and we hold stock in Australia for fast dispatch and fitment support.

Choose your rear leaf spring rate based on the constant weight you carry, not just occasional loads. A canopy, tray back, dual battery setup, water tanks or a fitted toolbox all add constant weight that a standard-rate spring wasn't designed for. Front spring choice should account for a steel bull bar and winch, which shift weight forward and can sag a standard-rate coil over time. Tell our team what accessories are fitted and we can confirm the right spring rate for your D-Max.
Fitment should be carried out by a qualified suspension installer or an experienced DIY mechanic with the right tools and torque specs on hand. A wheel alignment is mandatory after fitting, since ride height and castor angle both change with the lift. Allow around 500km for the new springs and shocks to settle into their working range before making a final call on ride height or handling. For sharper steering geometry at the new height, consider pairing this kit with upgraded control arms.
Toughdog has built suspension for Australian conditions for decades, valving foam cell struts and nitrogen shocks specifically for corrugations, dirt roads and heavy trade use rather than smooth bitumen alone. Each kit is backed by a manufacturer warranty and we stock the full range locally for fast dispatch. Have a look at the full Toughdog range if you're comparing lift heights or spring rates across other Tough Dog kits.
This kit suits D-Max owners who tow regularly, carry a tray or canopy for trade work, or head off-road with camping gear loaded in the tub. If your accessory load is more variable — a canopy some trips, empty the rest — it's worth comparing this kit against airbag suspension, which lets you adjust support on the fly rather than locking in one leaf spring rate.
This Tough Dog kit is in stock at our Australian warehouse for fast dispatch, and our team can confirm fitment and spring rate before you order. Browse our full lift kit range to compare options for your D-Max.

This Tough Dog kit is built for the Isuzu D-Max TF series produced from 2012 to 2020, covering both the 3.0L 4JJ1-TCX and 2.5L 4JJ1-TC turbo diesel engines. It suits dual cab, space cab and single cab models using the standard leaf-sprung rear end. If you're unsure of your exact build date or variant, our team can check your VIN or compliance plate against the kit before you order.
This kit lifts the D-Max 2" front and rear, achieved through foam cell front struts with raised coil springs and a matched progressive rear leaf pack. The lift is even front to rear, so the vehicle sits level rather than nose-high or rear-sagging. Final ride height can vary slightly depending on accessory weight already fitted to your vehicle.
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 Tough Dog Foam Cell front struts, 2 x front coil springs, 2 x Nitrogen gas rear shock absorbers and 2 x progressive multi-leaf rear spring packs. It also comes with rear U-bolt kits, greasable bushes, bump stops and the mounting hardware needed for installation. Upper and lower control arms are not included and are sold separately if your fitment requires them.
Yes, the progressive rate rear leaf pack and matched nitrogen gas shocks are sized to firm up the rear end under constant load, which improves stability when towing a trailer or caravan. Front foam cell struts help resist nose dive under brakes with a loaded tow ball weight. Tell us your typical tow weight and we can confirm this spring rate suits your setup or suggest a heavier-rated option.
A 2" lift on the D-Max can affect front control arm geometry and CV joint angles at full droop. Many owners run this kit with standard control arms without issue, but upgraded units correct the geometry more precisely at the new ride height. We recommend pairing this kit with upgraded control arms if you're running larger tyres or doing regular off-road work.
Yes, a wheel alignment is mandatory after installing this kit. Ride height, castor and camber all change once the vehicle is lifted, and running it unaligned will cause uneven tyre wear. Have the alignment done after the standard 500km settling period so the springs have taken their final set.
Yes, Tough Dog offers this kit in different front and rear spring rate options depending on your constant accessory load. If you're carrying a canopy, tray, dual battery system or towing regularly, a heavier-rated rear leaf pack is worth considering over the standard fitment. Contact our team with your accessory list and we'll match the right spring rate to your D-Max.
The 2" lift front and rear creates additional clearance that typically allows a moderate increase in tyre diameter over standard, subject to your wheel offset and any body modifications. Exact clearance depends on wheel width and offset, so check with our team before buying tyres. We can advise on suitable tyre sizes based on this kit's lift height and your wheel specs.
This kit is covered by Toughdog's manufacturer warranty against manufacturing defects in the struts, shocks and springs. As an Australian-based supplier, we handle warranty claims locally rather than sending components overseas. Keep your invoice and installation date on file, as most warranty claims require proof of purchase.
Yes, the foam cell strut and nitrogen gas shock combination is tuned to keep the ride comfortable on sealed roads while still handling corrugations and load-carrying off-road. It's a genuine daily-driver setup for D-Max owners who also tow or carry trade gear, not a track-only or off-road-only kit. Expect a firmer feel than a stock D-Max, particularly once heavier accessory loads are fitted.
