Dobinsons Nitro Gas 2" Lift Kit for Isuzu D-Max 2012-2019 — Complete Suspension Upgrade

This Dobinsons kit delivers 50mm (2 inches) of lift height measured at the chassis, providing clearance for tyres up to 32-33 inches depending on wheel offset and guard trimming. The lift improves ground clearance, approach/departure angles and water crossing capability while maintaining a balanced front-to-rear stance suitable for both unladen and loaded conditions. As an aftermarket suspension modification, this lift may affect certain aspects of manufacturer warranty on new vehicles — we recommend discussing suspension upgrades with your Isuzu dealer before installation. The Dobinsons components themselves are covered by comprehensive manufacturer warranty and are engineered to meet or exceed OEM durability standards.

This is a complete front and rear suspension lift kit including 2 x Dobinsons nitro gas front struts with 35mm bore, 2 x front coil springs rated for your specified load, 2 x nitro gas rear shock absorbers with 32mm bore, 2 x raised multi-stage leaf springs, 4 x heavy-duty zinc-plated U-bolts, and 1 x complete polyurethane bush kit with all necessary hardware. Everything required to lift and upgrade your D-Max suspension is included in the box. Additional components such as extended brake lines, differential drop spacers, castor correction bushes or upper control arms are not included but may be recommended depending on your intended tyre size and usage — our team can advise on complementary components during your order.

Yes, this Dobinsons kit significantly improves towing performance compared to factory suspension thanks to firmer shock valving, increased spring rates, and raised leaf springs that resist squat under tongue weight. The vehicle-specific valving provides excellent damping control when towing within your D-Max's rated capacity (3500kg braked), reducing body roll, improving stability on corrugated roads, and maintaining safe braking geometry. When selecting spring rates during ordering, specify your constant accessory load only — do not include trailer weight as this is considered occasional load. For frequent towing of heavy caravans near maximum capacity, consider adding airbag suspension to the rear for on-demand load levelling and additional support.

While this kit will install and function with factory control arms, upgrading to aftermarket upper control arms is highly recommended for optimal suspension geometry and performance. A 50mm lift pushes the factory castor angle outside ideal specifications, which can result in reduced steering returnability, altered handling characteristics and limited wheel travel at full droop. Aftermarket upper control arms with extended ball joint positions correct castor angle back to or beyond factory specifications, improve steering feel, increase wheel travel for better articulation off-road, and allow proper clearance for larger tyres. If you're planning to run 32-inch or larger tyres or undertake serious off-road touring, budget for control arm upgrades as part of your complete suspension package.

Yes, professional four-wheel alignment is absolutely mandatory after installing any lift kit, and this Dobinsons kit is no exception. Lifting your D-Max alters the suspension geometry including camber, castor and toe angles which directly affect tyre wear, steering feel and vehicle handling. A qualified alignment shop with 4WD experience should set your alignment to specifications appropriate for a lifted vehicle — this may differ from factory specifications. Expect to pay $150-250 for a quality four-wheel alignment. Failure to align after installation will result in rapid and uneven tyre wear, poor handling, and potentially unsafe driving characteristics. We also recommend re-checking alignment after the initial 500km break-in period once springs have fully settled.

Spring rate selection is based exclusively on your constant accessory load — the weight of items permanently installed on your vehicle, not occasional cargo or towing loads. During checkout you'll specify front and rear load categories (light, medium, heavy) based on your accessories. Typical front constant loads include bull bars (30-60kg), winches (30-40kg), long range tanks, and roof racks with permanent fixtures. Rear constant loads include canopies (60-150kg), drawers, dual batteries, toolboxes, and water tanks. Weigh your accessories if possible or use manufacturer specifications. Selecting springs too heavy for your actual load results in harsh ride and potential component damage. If between categories or unsure, choose the lighter option — springs can always be upgraded later but overly stiff springs cannot be softened.

This 2-inch lift provides clearance for tyres up to 32-33 inches in diameter (285/75R16 or 265/70R17) with appropriate wheel offset and minimal or no rubbing in most conditions. Actual clearance depends on wheel offset (0 to +20mm recommended), tyre brand/tread pattern, suspension articulation, and whether you've installed aftermarket control arms and diff drop components. Some minor guard trimming or removal of plastic inner guards may be required for 33-inch tyres at full lock and compression. If planning to run 33-inch or larger tyres, we recommend adding upper control arms to maximize clearance and prevent rubbing. Test your clearance thoroughly before committing to larger tyres, particularly if you plan serious off-road use with full suspension articulation.

All Dobinsons suspension components in this kit are covered by comprehensive manufacturer warranty against defects in materials and workmanship. Dobinsons stands behind their Australian-engineered products with warranty coverage that reflects their confidence in durability and quality. Specific warranty terms and duration vary by component type — shock absorbers and struts typically carry different coverage than springs and hardware. Warranty coverage requires proof of purchase, professional installation, and use within the component's designed application parameters. The warranty does not cover damage from incorrect installation, vehicle accidents, competition use, or modifications that alter the components from factory specification. For detailed warranty terms or to make a warranty claim, contact us with your purchase details and our team will facilitate the process directly with Dobinsons.

Absolutely — this kit is specifically designed to balance off-road capability with excellent on-road comfort and control for daily driving. The twin-tube nitro gas technology provides firmer damping than factory shocks for reduced body roll and better load control, while maintaining compliant ride quality over bumps, expansion joints and rough pavement. Many D-Max owners report improved highway stability and reduced float compared to worn factory suspension, particularly when loaded or towing. The vehicle-specific valving ensures the kit performs well both unladen during weekday commuting and fully loaded for weekend touring. While firmer than stock when new, the ride quality is refined and controlled rather than harsh. After the 500km break-in period, most owners find the ride actually more comfortable than factory suspension for long-distance highway driving.
