Selecting the correct spring rate is critical for optimal ride quality, handling and component longevity. When ordering, choose spring rates based on your constant accessory load only—the weight permanently fitted to your D-Max. Do not select heavier springs based on occasional loads or towing, as this will result in a harsh ride and potential damage to other suspension components. Common front accessories include steel bullbars (30-50kg), winches (30-40kg), and heavy-duty batteries, while rear constant loads include aluminium canopies (70-100kg), steel canopies (100-150kg), drawer systems (50-80kg), dual spare wheel carriers (40-60kg), long-range fuel tanks (20kg empty), and permanently mounted roof racks. If you're unsure about your accessory weight, our team can help calculate your requirements—towing a caravan or carrying occasional camping gear does not constitute constant load.
Professional installation by a qualified 4WD workshop is strongly recommended to ensure correct fitment, torque specifications, and safety. A full four-wheel alignment is mandatory after installation to prevent uneven tyre wear and maintain steering geometry—budget $180-$250 for alignment. All coil springs and leaf springs require a 500km break-in period where spring rates will settle by approximately 5-10mm as components bed in. For D-Max models with heavy front-end loads (winch + steel bar), consider pairing this kit with upgraded control arms to correct castor angle and maintain factory ride quality and handling characteristics.
With over 60 years of Australian suspension manufacturing heritage, Dobinsons is the trusted choice for serious tourers, tradespeople and 4WD enthusiasts who demand proven reliability. Every component is designed in-house by Dobinsons' team of suspension engineers, tested on purpose-built dyno and durability machines, and validated in real-world Australian conditions—from the Simpson Desert to the High Country. Dobinsons backs every product with comprehensive warranty support and exports to over 40 countries worldwide from their Australian head office. Explore the full Dobinsons suspension range for complementary upgrades including steering dampers, bushes, and extended shackles.
This kit is ideal for D-Max owners who tour regularly with roof-top tents, camping gear and recovery equipment, tradespeople running constant tray loads with canopies and toolboxes, and caravan or camper trailer towers requiring increased rear payload and stability. If you frequently carry near-maximum GVM loads, consider supplementing this kit with airbag suspension for on-demand load support and the ability to fine-tune ride height and firmness for varying loads. Weekend warriors, daily drivers seeking improved ground clearance, and off-road tourers tackling corrugated outback roads will all benefit from the Dobinsons Nitro Gas platform.

Yes, this kit is specifically engineered for all Isuzu D-Max third-generation (RG) models from 2020 to current, including single cab, space cab, and crew cab configurations with the 3.0L turbo diesel engine. The kit provides direct bolt-in fitment using OE mounting points with no modifications required. If you have a D-Max with aftermarket accessories or modifications, we recommend using our parts finder tool or contacting our team to confirm compatibility. All variants including SX, LS-M, LS-U, and X-Terrain models are compatible with this suspension system.
This Dobinsons kit delivers a genuine 50mm (2 inch) lift height front and rear, measured from standard unladen ride height. After the 500km break-in period, expect approximately 45mm of settled lift which provides clearance for up to 32 inch tyres (265/70R17 or 265/65R18) without rubbing on standard guards. For 33 inch tyres you may require minor trimming of plastic inner guards or aftermarket flares depending on wheel offset. The lift also improves approach angle by approximately 2-3 degrees and departure angle by 1-2 degrees for better off-road capability over obstacles and ruts.
The kit includes everything needed for a complete front and rear suspension upgrade: 2 x Dobinsons Nitro Gas front shock absorbers, 2 x raised front coil springs with selectable load ratings, 2 x Dobinsons Nitro Gas rear shock absorbers, 2 x raised rear leaf springs with selectable load ratings, 4 x heavy-duty U-bolts for leaf spring mounting, 1 x polyurethane bush kit, and all necessary mounting hardware. The kit does not include upper control arms, extended brake lines, diff drop components or castor correction bushes which may be required depending on your specific vehicle configuration and intended use. Our team can advise on complementary components during your order.
Absolutely—this kit is an excellent choice for D-Max owners who regularly tow caravans, camper trailers, or work trailers up to the vehicle's rated towing capacity. The raised rear leaf springs feature progressive rate design that stiffens under load to maintain ride height and reduce squat when hitched, while the Nitro Gas rear shocks provide superior damping control to minimise trailer sway and porpoising. The larger shock body sizes (60mm front, 51mm rear) with increased oil capacity resist fade during extended highway towing. For maximum towing performance and adjustability, many customers pair this kit with airbag suspension which allows on-demand load support and height adjustment.
Upper control arms are not mandatory for a 50mm lift on the D-Max 2020-on, but they are highly recommended if you're running a heavy front-end setup with steel bullbar and winch (combined 60kg+). Upgraded control arms restore factory castor angle which can be reduced by lifting, improving steering return, high-speed stability and on-road handling. Without correction you may notice slightly heavier steering and reduced self-centering. Standard control arms will function safely, but aftermarket arms with castor correction and strengthened ball joints deliver noticeably better geometry and long-term durability. Our team can recommend suitable options during checkout based on your accessory configuration.
Yes, a full four-wheel alignment is absolutely mandatory after installing any suspension lift kit, including this Dobinsons system. Lifting your D-Max changes the suspension geometry and alignment angles including camber, castor and toe settings. Without proper alignment you will experience rapid and uneven tyre wear (especially inner edge wear on front tyres), wandering or vague steering feel, and reduced handling performance. Budget approximately $180-$250 for a comprehensive alignment at a reputable alignment shop with 4WD experience. Insist on a printout showing before and after readings to confirm all settings are within manufacturer specifications for lifted vehicles.
Yes, and selecting the correct spring rates is one of the most important aspects of your order for optimal ride quality and performance. When placing your order you'll be asked to select front and rear spring rates based on your constant accessory load—the permanent weight of bullbars, winches, canopies, drawers and other fitted accessories. It's critical to select rates based only on constant loads, not occasional camping gear or towing weight. A common configuration for D-Max tourers is medium-heavy front springs (for steel bar + winch) and medium rear springs (for aluminium canopy). Our team can help calculate your exact requirements if you provide a list of fitted accessories and their approximate weights.
With a genuine 50mm lift (settling to approximately 45mm after break-in), you can comfortably fit 265/70R17 tyres (31.6 inches diameter) or 265/65R18 tyres (31.5 inches) with standard wheel offset (approximately +20 to +45mm) without any rubbing or guard modifications. These sizes are popular upgrades from the factory 265/60R18 (30.5 inch) and provide improved ground clearance, better off-road traction, and more aggressive appearance. If you want to run 285/70R17 tyres (32.7 inches), you may experience minor rubbing at full lock or full suspension compression, requiring small trimming of plastic inner guards. Wheel offset also plays a role—wheels with lower offset (0 to +20mm) push tyres outward and may require guard modifications even with 265 width tyres.
All Dobinsons suspension components including shock absorbers, coil springs, and leaf springs are backed by Dobinsons' comprehensive manufacturer warranty against defects in materials and workmanship. Shock absorbers typically carry 12-24 month warranty depending on application (check product documentation for specific terms), while springs are covered for defects including sagging or breakage under normal use. Warranty claims are handled directly through Dobinsons Australia with support from our team. To maintain warranty coverage, the kit must be installed by a qualified mechanic with correct torque specifications, and the vehicle must not exceed GVM or operate outside normal use parameters. Keep all installation receipts and documentation for warranty purposes.
Yes, the Dobinsons Nitro Gas kit is engineered for excellent daily driving comfort while delivering superior off-road capability when you need it. Unlike budget lift kits that compromise on-road manners, Dobinsons uses vehicle-specific valving, quality Fuchs oil, and NOK multi-lip seals to provide smooth damping over bumps, reduced road noise, and stable highway cruising at 100-110km/h. The twin-tube design with larger oil capacity maintains consistent performance across varying temperatures and speeds. You'll notice improved stability compared to factory suspension, especially when loaded or towing, while still maintaining compliant ride quality over corrugations and rough roads. Thousands of D-Max owners run this kit as their everyday suspension setup for commuting, work duties, and weekend touring without compromise.
Proper kit that handles work and play
Been running this Dobinsons 2 inch lift on my D-Max for about 6 months now, daily drives to sites plus weekend trips down the Cape. The ride quality is spot on even with a full load of tools and gear in the tray, and it's handling the corrugated tracks way better than the stock setup ever did. Worth every cent for a proper Australian-engineered kit.(5)
Proper Aussie Engineering That Handles the Punishm
Been running this 2-inch Dobinsons kit on my D-Max for the past six months through some pretty rough Cape York tracks and it's handled everything I've thrown at it. The ride quality is genuinely impressive – still comfortable when empty but planted and controlled when loaded up with camping gear and water. After years of trying different setups, these twin-tube shocks are the real deal for serious touring, none of that harsh bouncing you get with cheap lifts.(5)
Perfect Setup for Our Family Adventures
Finally got the Dobinsons 2 inch lift kit fitted to our 2021 D-Max and the difference is night and day. We've done two trips out to the Flinders Ranges since the install and the ride quality is brilliant – handles the corrugations way better than stock and sits level even with the camper trailer hooked up. The extra clearance gives me so much more confidence on rough tracks, and the kids reckon the backseat is actually more comfortable now. Well worth the investment for anyone serious about getting off the beaten track with the family.(5)
Perfect Setup for Work and Weekend Trips
Had this 2 inch Dobinsons kit fitted to my 2021 D-Max about three months back and it's been cop a hiding daily between work sites and a couple of runs out to the high country. Ride quality is heaps better than stock even with tools and materials in the tray, and it handles the van on weekends without any dramas. Worth every cent for an Aussie-made setup that actually does what it's supposed to.(5)
Handles the Corrugations Like a Dream
Had this Dobinsons 2-inch lift fitted before heading up the Canning Stock Route last month and it completely transformed how the D-Max handled the whoops and washboard sections. The twin-tube shocks soaked up everything while keeping the rear end planted even with 400kg of water and recovery gear on board. Build quality is typical Dobinsons – proper Australian engineering that's built to cop a hiding in the real outback, not just weekend fire trail runs.(5)
