Selecting the correct spring rates is critical for optimal performance and ride quality. When ordering, choose spring rates based on your constant accessory load only — the weight permanently installed on your vehicle. Constant loads include bullbars, winches, steel trays, canopies, long-range fuel tanks, dual battery systems, drawers and roof racks. Do NOT factor in occasional loads such as camping gear, passengers, tools or towing weight when selecting spring rates, as this will result in over-sprung suspension, harsh ride quality and potential damage to other suspension components. Common front accessories that affect spring selection include steel bullbars (25-40kg), winches (30-50kg) and steel replacement bonnets, while rear constant loads include steel trays, canopies, dual battery systems, water tanks and drawer systems. If you're unsure about your total accessory weight, our team can help calculate your requirements — simply provide a list of your fitted accessories.
Professional installation by a qualified 4WD suspension specialist is strongly recommended for this kit, though experienced DIY mechanics with appropriate tools can complete the installation. Wheel alignment is mandatory after installation to ensure correct toe, camber and caster settings, preventing premature tyre wear and maintaining safe handling characteristics. All Dobinsons shock absorbers require a 500km break-in period during which the internal seals bed in and damping characteristics settle — avoid extreme off-road driving during this period. Depending on your final lift height and intended use, you may benefit from pairing this kit with upgraded control arms to correct ball joint angles and maximize suspension travel, particularly if running larger tyres or touring with heavy loads.
Dobinsons has been engineering premium 4WD suspension solutions for over 60 years, with a reputation built on real-world Australian outback testing and proven durability in our harshest conditions. Every Dobinsons product is backed by comprehensive warranty and supported by a network of Australian dealers and installers who understand the unique demands placed on touring and working 4WDs. Trusted by grey nomads, tradespeople, emergency services and serious tourers across Australia, Dobinsons represents the gold standard in reliable, long-lasting suspension performance. Explore the complete Dobinsons suspension range to find complementary components for your build.
This kit is ideal for Isuzu D-Max owners who demand the best — touring enthusiasts covering long distances with roof-top tents and camping equipment, tradespeople carrying constant tool and equipment loads, and caravan towers who need stable, fade-resistant performance under heavy tongue weight. The adjustable height feature makes it perfect for owners who frequently change their setup or run different tyre sizes seasonally. If you're a heavy hauler regularly at or near GVM, consider supplementing this kit with airbag suspension for additional load support and the ability to level your vehicle when towing or carrying uneven loads in the tray.

This kit is specifically engineered for Isuzu D-Max models manufactured between June 2012 and June 2020, covering both the pre-facelift and facelifted versions of the first-generation platform. It fits all variants including SX, LS-M, LS-U and LS-Terrain models within this date range. This kit does NOT fit the 2020.5-onwards (mid-2020+) second-generation D-Max which uses a completely different suspension platform. If you're unsure of your exact build date or variant, check the compliance plate on your door frame or contact our team with your VIN for confirmation.
The front lift height is adjustable using the coilover 'C' spanner system, typically delivering between 35-50mm of lift depending on your spring rate selection, accessory load and desired ride height setting. The rear provides a consistent 40mm lift from the raised leaf spring pack. Total lift height will vary based on your constant accessory load — heavier front-end accessories like bullbars and winches will compress springs more, while lighter setups achieve maximum lift. The adjustability allows you to fine-tune your stance to accommodate larger tyres while maintaining proper suspension geometry.
This comprehensive kit includes everything needed for a complete front and rear suspension upgrade: 2 monotube IFP adjustable front shock absorbers, 2 front coil springs (with coilover adjusters and spanners), 2 monotube IFP rear shock absorbers, 2 x 40mm raised rear leaf springs, 4 heavy-duty U-bolts, and a complete polyurethane bush kit for the leaf spring installation. You'll select your preferred front coil and rear leaf spring rates during checkout based on your constant accessory load. Note that extended brake lines, upper control arms, differential drop kits and other ancillary components are sold separately and may be required depending on your final lift height and vehicle setup.
Absolutely — this Dobinsons Monotube IFP kit is an excellent choice for towers, particularly when you select appropriate spring rates for your towing needs. The monotube design provides superior heat dissipation and fade-resistant performance during extended highway towing, while the IFP technology maintains consistent damping under the increased loads. The 40mm raised rear leaf springs help counteract rear squat from tongue weight, and higher-rate spring options are available for regular heavy towing. For maximum towing performance and the ability to level your vehicle under varying loads, consider pairing this kit with supplementary airbag suspension which allows on-the-fly pressure adjustment.
Control arm upgrades are not mandatory for this lift height range, but are strongly recommended for optimal suspension geometry and performance. The 40-50mm lift provided by this kit begins to alter ball joint angles and can reduce suspension articulation, particularly when combined with larger tyres. Upgraded control arms with corrected geometry restore proper suspension operation, maximize wheel travel and reduce stress on ball joints and CV boots. If you're planning serious off-road touring, running 32-inch+ tyres, or want to maximize the capability of your investment, budget for quality aftermarket control arms to be installed at the same time.
Yes, professional wheel alignment is absolutely mandatory after installing any lift kit, including this Dobinsons system. The installation process and change in ride height will alter your vehicle's toe, camber and caster angles, which directly affect tyre wear, handling stability and steering feel. Driving without proper alignment can cause rapid and uneven tyre wear, pulling to one side, and potentially dangerous handling characteristics. Book your alignment with a shop experienced in modified 4WDs who can accommodate the increased ride height and understand the specific alignment requirements of lifted D-Max models.
Select spring rates based solely on your constant accessory load — the permanent weight installed on your vehicle at all times. Calculate the weight of bullbars, winches, steel trays, canopies, roof racks, long-range tanks, dual batteries and drawer systems. Do NOT include camping gear, passengers, tools or towing equipment as these are occasional loads. Front accessories typically range from 40kg (no bullbar) to 150kg+ (full steel bar with winch), while rear constant loads vary from near-zero (standard tray) to 200kg+ (canopy with drawers and tanks). If you select springs that are too heavy for your actual constant load, you'll experience harsh ride quality and poor small-bump compliance. When in doubt, contact our team with a list of your accessories for personalized spring rate recommendations.
With this 40-50mm lift and appropriate wheel offset, most D-Max owners can comfortably fit 32-inch tyres (285/70R17 or 265/70R17 depending on width preference) with minimal to no rubbing during full suspension articulation. Some owners successfully run 33-inch tyres (285/75R17) with minor trimming of plastic inner guards. Exact fitment depends on your wheel offset, tyre brand (tread patterns vary in actual width), and whether you've installed aftermarket control arms for additional clearance. Test fitment at full steering lock and full suspension compression before committing to a tyre purchase. Remember that larger, heavier tyres may require spring rate adjustments and will affect your speedometer calibration.
Dobinsons suspension products are backed by comprehensive manufacturer warranty covering defects in materials and workmanship. Specific warranty periods vary by component — shock absorbers and springs typically carry extensive coverage when installed and maintained according to specifications. Warranty coverage requires professional installation by a qualified technician, proof of purchase, and adherence to recommended service intervals including the critical 500km initial inspection. The warranty does NOT cover damage from accidents, misuse, incorrect installation, or failure to maintain proper wheel alignment. Retain all installation documentation and service records to ensure warranty validity. Contact us for specific warranty terms and conditions applicable to your kit.
Yes, this Dobinsons Monotube IFP kit delivers surprisingly refined on-road comfort despite its heavy-duty construction, making it ideal for dual-purpose vehicles that serve as both daily drivers and weekend tourers. The monotube design provides more progressive damping characteristics than budget twin-tube alternatives, absorbing small road imperfections while maintaining control over larger bumps. Ride quality depends significantly on selecting appropriate spring rates — over-sprung suspension (springs too heavy for your load) will feel harsh, while correctly matched springs provide compliant, comfortable highway cruising. During the initial 500km break-in period, damping will feel slightly firm before settling into optimal characteristics. Expect a noticeable improvement over worn factory suspension in both comfort and control.
Perfect upgrade for my work truck
Been running this Dobinsons adjustable lift kit on my 2015 D-Max for about 6 months now and it's handled everything I've thrown at it. Daily drives to job sites are way more comfortable than the stock setup, even with a loaded tray. The adjustable height feature is brilliant for when I need to level out the rear with tools and materials on board, and it's still performed great on the weekend beach runs.(5)
Perfect upgrade for our family camping adventures
Fitted this Dobinsons adjustable height lift kit to our 2015 D-Max about six months ago and it's been brilliant for our monthly camping trips down the coast and up to the high country. The ride quality is noticeably smoother than the old setup, especially when we're loaded up with the camper trailer and all the kids' gear. Really happy with how it handles the corrugated tracks without bouncing the family around, and the adjustable height feature has been handy for different load scenarios.(5)
Massive improvement for my work ute
Been running the Dobinsons adjustable height kit on my Dmax for about 6 months now and it's transformed how the ute handles with a full load of tools and materials. The ride quality is noticeably better than stock, even when I'm empty, and I've had no issues with the couple of beach and bush tracks I've taken it down on weekends. Really happy with the value for money compared to some of the other kits I looked at.(5)
