The Dobinsons MRA Adjustable Lift Kit suits the Isuzu D-Max Series II (RG) 2021-on and delivers a selectable 2" or 3" lift with 3-way externally adjustable remote-reservoir shocks front and rear, each running a 50mm bore monotube design. Front coils and rear leaf springs are matched to your constant accessory load, from bullbars to canopies, keeping ride height correct under load. Check all suspension parts for the Isuzu D-Max to confirm fitment for your build. In stock in Australia with Dobinsons' manufacturer warranty and fitment support from our team.

Choose your front and rear spring rate based on constant accessory load, not occasional load. Constant load includes a bullbar, steel or aluminium tray, canopy, drawer system, dual battery setup, long-range fuel tank or a permanently loaded roof rack. Camping gear, recovery gear and towing weight should not drive spring selection — an oversprung setup rides harshly and wears bushes and shocks faster than a correctly matched one.
Fitment should be carried out by an experienced 4WD suspension installer given the number of components involved. A four-wheel alignment is required after fitting to correct camber, caster and toe. Shocks need roughly 500km to bed in, so avoid hard off-road use during this period. If you're running the kit toward the 3" end of the range, ask about upgraded control arms to restore CV and steering geometry.
Dobinsons has built suspension components for Australian conditions for decades, and the MRA range carries this same design approach into a fully adjustable shock. Every kit is backed by Dobinsons' manufacturer warranty and supported by our team's fitment knowledge on the D-Max platform specifically. You can view the full Dobinsons range to compare this kit against other lift options for your vehicle.
This kit suits D-Max owners running a bullbar, tray and canopy who need the rear spring rate matched to that permanent load, as well as tourers who tow regularly and want adjustable damping to firm up the rear for a loaded trailer. Tradies carrying steady payloads and grey nomads running a caravan both fall into this category. For anyone regularly at or near GVM, pairing this kit with airbag suspension adds on-demand load levelling on top of the coil or leaf spring rate.
This Dobinsons MRA kit ships from our Australian warehouse with fast dispatch nationwide. Our team can talk through spring rate selection, install requirements and alignment for your specific D-Max build — get in touch before you order if you're unsure, or browse our full lift kit range to compare against other options.
This kit is built specifically for the Isuzu D-Max Series II (RG) built from 2021-on, fitted with the 3.0L turbo diesel engine. It is not a match for the earlier Series I D-Max (2012-2020), which uses a different chassis and suspension mounting layout. If you're unsure which series you have, our parts finder for the Isuzu D-Max will confirm fitment, or you can contact our team with your build date.
The Dobinsons MRA kit is adjustable across a 2" to 3" lift range front and rear. The exact height within that range depends on the spring rate selected and any accessory load fitted at the time of installation. Front and rear height can be set independently to suit your tyre size and stance preference.
The kit includes two MRA adjustable front shocks and two MRA adjustable rear shocks, both with external 3-way damping adjustment and remote reservoirs. It also includes front coil springs and rear leaf spring assemblies matched to your selected load rate, plus the U-bolts, shackle bushes and mounting hardware needed to fit them. Upper control arms are not included and are sold separately.
Yes. The rear leaf springs are available in different load rates so you can match them to your constant accessory load, and the 3-way adjustable damping lets you firm up rebound and compression when a trailer or caravan is hitched. For D-Max owners towing at or near GVM regularly, we'd also suggest looking at airbag suspension to add load-levelling on top of the spring rate.
It's not compulsory, but it's worth considering once you're running toward the 3" end of the lift range. A taller lift changes the upper control arm angle, which affects CV joint operating angle and camber. Our team can advise whether adjustable control arms are needed for your specific ride height and driving use.
Yes, a four-wheel alignment is required after this kit is installed. Changing ride height alters camber, caster and toe, and correct alignment protects tyre wear and keeps the vehicle tracking straight. This should be done using proper alignment equipment, not just a manual toe check.
Yes, both the front coil springs and rear leaf springs are available in multiple load ratings. Selection should be based on your constant accessory load — bullbar, tray, canopy, drawers, dual battery and long-range tank — rather than occasional camping or recovery gear. Our team can help match the correct rate front and rear before you order.
The 2"-3" lift typically provides clearance for up to a 33" all-terrain or mud-terrain tyre on most D-Max builds. Final clearance depends on wheel width, offset and whether any guard or bar work has been done. If you're planning a specific tyre and wheel combination, check with our team before ordering.
This kit is backed by Dobinsons' manufacturer warranty covering the shocks and springs against manufacturing defects. Our team can provide the specific warranty term and claims process at the time of purchase. We also provide fitment support if you have questions before or after installation.
Yes. The 3-way adjustable damping means the shocks can be set softer for unladen daily use and firmed up when carrying load or towing, rather than being a fixed compromise. A 500km bed-in period is normal after fitting, during which damping will settle in. Outside of that, it's designed to be run day-to-day as well as on tracks.
