Dobinsons 2 Inch Nitro Gas Lift Kit — Isuzu D-Max 2008-2012 Series 1

This kit delivers approximately 2 inches (50mm) of lift at both the front and rear of your Isuzu D-Max 2008-2012. Actual lift height can vary slightly depending on your vehicle's current constant accessory load including bull bars, canopies, drawer systems and other permanent fitments. Heavier constant loads may result in slightly less final lift height, while lighter vehicles may achieve marginally more. The kit is designed to restore factory ride height on heavily loaded vehicles while providing genuine lift capability for off-road clearance and larger tyre fitment. After the initial 500km break-in period, springs will settle and you should check final ride height and have your alignment rechecked if necessary.

This complete kit includes 2x Dobinsons Nitro Gas front struts (35mm bore), 2x Dobinsons Nitro Gas rear shock absorbers (32mm bore), 2x Dobinsons 40mm raised rear leaf springs with load-specific ratings, 4x heavy-duty U-bolts with all nuts and washers, and 1x Dobinsons polyurethane bush kit. All mounting hardware required for installation is included along with fitment instructions. This is everything you need for a complete front and rear suspension upgrade. Note that upper control arms, extended brake lines, castor correction components and steering dampers are not included but may be recommended depending on your specific vehicle setup and intended use.

Yes, this kit significantly improves towing performance compared to factory suspension thanks to the heavy-duty 40mm raised leaf springs which are specifically load-rated for increased payload capacity and towing stability. The twin-tube nitro gas shocks feature vehicle-specific valving that controls body roll and maintains consistent damping under towing loads, reducing rear squat and improving trailer control. The increased oil capacity and larger bore sizes help prevent shock fade during extended highway towing or when navigating corrugated roads with a trailer attached. For D-Max owners who tow regularly or with highly variable loads, we also recommend considering adjustable airbag suspension as a complementary upgrade for on-demand load levelling and enhanced towing stability.

While this 2-inch lift kit can be installed with factory control arms, upgrading to aftermarket control arms is highly recommended for D-Max owners running heavy constant loads, larger tyres (32 inches and above), or those who regularly drive off-road. Upgraded control arms restore correct castor and camber angles after lifting, which improves steering feel, high-speed stability and tyre wear patterns. They also provide increased wheel travel and clearance for larger tyres, and typically feature stronger construction with better quality bushings for improved durability. If you're planning a comprehensive suspension upgrade or running significant modifications, budget for control arms at the same time to maximise the performance and longevity of your new lift kit.

Yes, a full four-wheel alignment is absolutely mandatory after installing any lift kit including this Dobinsons kit. Lifting your vehicle changes suspension geometry including castor, camber and toe angles, which directly affects steering feel, handling characteristics, tyre wear and vehicle safety. Even though this is a direct bolt-in kit, the change in ride height alters the relationship between suspension arms, steering linkages and wheel position. A professional alignment performed by a workshop experienced with lifted 4WDs will ensure your D-Max tracks straight, handles predictably, and your tyres wear evenly. Plan to have alignment checked again after the 500km break-in period once springs have fully settled into their final operating height.

Yes, Dobinsons manufactures different spring rates to suit varying constant accessory loads, and selecting the correct rate is critical for optimal ride quality and vehicle performance. When ordering, you'll need to calculate your constant load — this includes only permanent accessories like bull bars, canopies, drawer systems, winches, roof racks, dual batteries and long-range tanks. Do NOT include occasional loads like camping gear, passengers or towing weight, as selecting too heavy a spring rate will result in an overly harsh ride and potential stress on other suspension components. If you're unsure about your total constant load or which spring rate to select, our suspension specialists can help calculate your requirements and recommend the appropriate front and rear spring rates for your specific D-Max setup.

This 2-inch lift kit will provide clearance for moderately larger tyres on your Isuzu D-Max 2008-2012, typically allowing 31-32 inch tyres without major rubbing issues on standard width rims with appropriate offset. The actual maximum tyre size depends on several factors including wheel offset, tyre width, tread pattern aggressiveness, and whether you've trimmed any plastic guards or fitted aftermarket flares. For optimal clearance with 32-inch or larger tyres, you may need to consider minor guard trimming, wheel spacers, or wheels with different offset. Keep in mind that larger, heavier tyres affect gearing, fuel economy, speedo accuracy and braking performance, and may require recalibration or complementary modifications. Our team can provide specific tyre fitment advice based on your chosen wheel and tyre combination.
