Rear leaf springs are a bolt-on job for an experienced DIY mechanic with a hoist and routine work for any suspension workshop. A wheel alignment is required afterwards because ride height changes front geometry. Replacing U-bolts and bushes at the same time is strongly recommended — the originals are stretched to yield on installation and old bushes cause squeaks and premature wear. Both are available as add-ons above.
Dobinsons has been designing and manufacturing 4WD suspension in Australia for decades, with springs wound and dampers valved for local loads, corrugations and touring distances rather than adapted from an overseas market spec. Every part is backed by a Dobinsons manufacturer warranty. View the full Dobinsons range to match the rest of your build.
Isuzu D-Max 07/2020-On owners carrying a constant rear load: trays and toolboxes, canopies, drawers and long-range tanks, or towing with meaningful ball weight. If your load varies trip to trip, airbag helper kits add adjustability alongside the leaf pack.

Yes — these Dobinsons leaf packs are built for the Isuzu D-Max 07/2020-On rear axle and bolt to the factory mounts. This listing suits the 07/2020-on D-Max (RG). Earlier D-Max models use different parts.
Pick based on the weight that sits on the rear axle permanently — tray or canopy, drawers, water, dual battery, plus towball weight. Aim to sit in the middle of the rated range rather than at the top. Lightly loaded vehicles usually ride better on a medium duty or parabolic pack.
The lift for each pack is shown in the dropdown and the options table. Final height depends on existing spring sag and the constant load carried, and new springs settle slightly over the first 500km.
New U-bolts are strongly recommended with any leaf spring change because the originals are stretched to yield when first installed. Fresh bushes and greasable shackles prevent squeaks and premature wear. All three are optional add-ons above so you can order everything together.
Yes. Choose the 2" lift option on this page and pair it with the matching Dobinsons dampers linked above — springs set the lift height and load rating, and the matched shocks control it. The same approach with 3" options builds a 3 inch lift kit for the D-Max.
