The Dobinsons Nitro Gas 2" Lift Kit suits the Holden Colorado 7 Wagon (2012-2016) and pairs twin-tube nitro gas struts up front with matched rear shocks and vehicle-specific coil springs. Larger 60mm/51mm shock bodies and 35mm/32mm bores cut heat build-up on corrugations, while the 2" lift adds ground clearance for bigger tyres and touring gear. Backed by a manufacturer warranty and dispatched from Australian stock, this lift kit comes with fitment support from our team.

Choose your spring rate based on constant accessory load only — the permanent weight your Colorado 7 carries every day, not occasional camping gear or passengers. Common front constant loads include a bullbar, winch or bash plates. Common rear constant loads include a drawer system, dual battery tray or long-range fuel tank. If you're unsure which rate suits your build, our team can confirm the correct front and rear springs before you order.
This kit bolts in as a direct OE replacement and suits professional installation or an experienced DIY mechanic with the right equipment. A four-wheel alignment is mandatory after fitting to restore correct geometry and even tyre wear. All Dobinsons springs and shocks need a 500km break-in period before they reach final ride characteristics. If you're adding a bullbar or winch, pair this kit with upgraded control arms to correct castor angle at the new ride height.
Dobinsons has manufactured suspension in Australia for over 60 years and supplies touring, trade and 4WD club customers here and overseas. Every shock is dyno-tested and run through in-house durability cycles before it leaves the factory. Backed by a manufacturer warranty and stocked locally, the Dobinsons suspension range is built for owners who use their vehicle hard.
This kit suits Colorado 7 owners after better ground clearance for beach and track access, plus tradies running the wagon as a daily driver who need predictable handling loaded or empty. If you tow a caravan or carry heavy rear loads most of the time, ask us about adding airbag suspension for on-demand load support without changing your unladen ride height.

Yes — this kit is designed specifically for the Holden Colorado 7 Wagon (RG series) built 2012-2016. It's a direct bolt-in replacement for the factory struts, shocks and springs. Confirm your build date against the fitment table above, and contact us if you're unsure.
This kit gives a 2" lift at the front and 2" at the rear compared to standard ride height. That extra clearance opens room for larger tyres and improves departure angle. Actual ride height also depends on constant accessory load, so correct spring rate selection is important.
Please note that all assembled struts are dispatched at a height based on our experience and the manufacturer’s specifications for the advertised lift. Coil springs and leaf springs are also manufactured according to the advertised height and constant-load rating. Actual vehicle height may vary depending on the vehicle and the weight of fitted accessories. Further adjustment may therefore be required after installation. The installer may use coil spacers or adjust the struts at their discretion to achieve the desired height. We are not responsible for vehicle-specific height variations or any additional adjustments required after installation.
The kit includes two Dobinsons Nitro Gas front struts, two rear shock absorbers, and matched front and rear coil springs raised 2". Natural rubber bushings and mounting hardware are included. Upper control arms are not included and are sold separately.
Yes, when matched to the correct rear spring rate for your constant load. The nitro gas shocks and vehicle-specific springs improve load control and reduce rear sag under a loaded canopy or drawer system. For frequent caravan towing, we recommend pairing with airbag suspension for adjustable support.
If you're adding a bullbar, winch or steel bumper, we recommend upgraded control arms to restore correct castor angle at the raised ride height. Without them, steering feel and geometry can be slightly off. Our team can confirm whether your setup needs this upgrade.
Yes, a full four-wheel alignment is mandatory after installing this kit. It ensures correct suspension geometry, even tyre wear and predictable handling at the new ride height. Skipping alignment can cause uneven tyre wear and affect handling.
Yes, Dobinsons offers different spring rate options for front and rear based on your constant accessory load. Tell us what you're carrying permanently — bullbar, winch, drawers, dual battery — and we'll help you pick the right rate. Occasional loads like camping gear don't factor into this choice.
The 2" lift height typically allows for a moderately larger tyre than standard, subject to your wheel offset and any bodywork rubbing points. We recommend confirming your exact tyre size with our team before purchase. Combining this lift with correct wheel offset gives the best clearance results.
This kit is backed by Dobinsons' manufacturer warranty, supported directly through our Australian team. We handle warranty enquiries locally rather than you needing to deal with an overseas supplier. Contact us for the specific warranty period and terms applicable to this kit.
Yes. The vehicle-specific valving is tuned to balance unladen daily comfort with load-carrying control, so the Colorado 7 doesn't ride harsh when empty. Natural rubber bushings also reduce noise and vibration for everyday use. Expect a 500km break-in period before the ride settles to its final feel.
