Dobinsons Nitro Gas 2-Inch Lift Kit for Holden Colorado 7 Wagon — Complete Suspension Upgrade

This Dobinsons kit provides approximately 50mm (2 inches) of lift over factory ride height when measured at the wheel arch. Actual lift height can vary slightly depending on your constant accessory load, spring rate selection, and whether your vehicle currently sits below factory height due to worn OE suspension. The 2-inch lift provides improved ground clearance for off-road touring, better approach and departure angles, and allows fitment of larger diameter tyres (typically up to 265/70R17 or similar, though clearance should be checked with full suspension articulation). This moderate lift height maintains excellent on-road manners for daily driving while delivering genuine off-road capability improvements.

This complete kit includes 2 x Dobinsons Nitro Gas front struts, 2 x Dobinsons front coil springs, 2 x Dobinsons Nitro Gas rear shock absorbers, 2 x Dobinsons rear coil springs, plus all necessary mounting hardware and bushings for direct OE fitment. The springs are available in multiple load ratings which you select at checkout based on your constant accessory load. All shocks feature twin-tube nitro gas construction with premium NOK seals, Fuchs oil, and natural rubber bushings pre-installed. Note that upper control arms, extended brake lines, diff drop kits or other geometry correction components are not included and may be required depending on your vehicle's existing modifications and intended use.

Yes, this Dobinsons Nitro Gas lift kit significantly improves towing performance compared to factory suspension, particularly when paired with correctly selected spring rates for your constant load. The twin-tube shock absorbers feature larger bodies, increased oil capacity and firmer vehicle-specific valving that reduces shock fade and maintains control under heavy towing loads. However, you must select your spring rates based on constant accessory load only — towing is considered an occasional load. For regular heavy towing or caravan use, we strongly recommend supplementing this kit with airbag suspension helpers, which allow you to adjust load support on-demand without compromising unladen ride quality. This combination delivers the best of both worlds for Colorado 7 owners who tow recreationally.

Upper control arms are not included in this kit and are not mandatory for a 2-inch lift on the Colorado 7, but they are highly recommended if you're carrying significant front-end weight from accessories like steel bullbars, winches or heavy-duty bumpers. Upgrading to adjustable upper control arms allows you to restore factory castor angle after lifting, which maintains proper steering feel, reduces tyre wear and improves high-speed stability. If your Colorado 7 will remain relatively light in the front or you're on a budget, you can install this lift kit first and add control arms later if you notice any steering or handling changes. Our technical team can assess your specific accessory setup and provide personalised recommendations.

Yes, a full four-wheel alignment is absolutely mandatory after installing any lift kit, including this Dobinsons 2-inch kit for the Colorado 7. Lifting your vehicle changes suspension geometry angles including camber, castor and toe settings, which if left unadjusted will cause uneven tyre wear, poor handling, and potentially unsafe steering characteristics. You should have the alignment performed by a qualified suspension specialist or 4WD workshop familiar with lifted vehicles, as factory alignment specifications may need to be adjusted. The alignment should be checked again after the initial 500km break-in period once springs have fully settled and components have seated, ensuring optimal long-term performance and tyre life.

You must select spring rates based solely on your constant accessory load — the permanent weight your vehicle carries every single day. Do not factor in occasional loads like camping gear, passengers or towing, as this will result in overly stiff springs and harsh ride quality. Common constant front loads include bullbars, winches, upgraded bumpers and long-range fuel tanks. Common constant rear loads include drawer systems, dual batteries, canopies, long-range tanks and permanent storage. During checkout, you'll be asked to specify your constant load for front and rear separately. If you're unsure, our team can help you calculate your accessory weights and recommend appropriate spring rates to achieve the best balance of comfort and load-carrying capability.

With the 2-inch lift from this Dobinsons kit, most Holden Colorado 7 Wagons can accommodate tyres up to approximately 265/70R17 (31.6-inch diameter) or 265/65R18 depending on your wheel offset and specific body variant. However, tyre clearance depends on several factors including rim offset, tyre brand (some run larger than others at the same size), and whether you've fitted aftermarket bullbars or other accessories. We strongly recommend test-fitting your chosen tyres at full steering lock and full suspension compression before committing to a purchase. Some minor trimming of plastic inner guards may be required for maximum clearance. For larger tyres beyond 265/70R17, you may need additional modifications such as upper control arms or body mount chop to prevent rubbing during off-road articulation.

This Dobinsons Nitro Gas lift kit is backed by Dobinsons' comprehensive Australian manufacturer warranty, covering defects in materials and workmanship under normal operating conditions. Warranty terms vary by component (shock absorbers and springs have different coverage periods), and full warranty details are provided with your kit upon purchase. Dobinsons has built their reputation over 60 years on product quality and customer support, with warranty claims handled efficiently through their Australian head office. To maintain warranty coverage, the kit must be installed by a qualified mechanic or experienced DIY installer following Dobinsons' installation guidelines, and you should retain proof of purchase. Our team can provide full warranty documentation and answer any specific warranty questions before you order.

Absolutely — this Dobinsons Nitro Gas kit is specifically engineered to deliver an excellent balance between on-road comfort for daily commuting and off-road capability for weekend touring. The twin-tube shock design with vehicle-specific valving provides controlled damping that absorbs road imperfections smoothly during highway driving, while the increased oil capacity and firmer valving prevents bottoming and shock fade on corrugated tracks. Natural rubber bushings reduce noise and vibration for car-like refinement, and the matched coil springs maintain good unladen ride quality (when correctly rated for your constant load). Many Colorado 7 owners use this kit on work vehicles that see daily suburban driving during the week and family touring or beach trips on weekends, with excellent feedback on ride quality in both scenarios. Proper spring rate selection is key to achieving the best daily driving comfort.
