Choosing the right rear leaf spring rate depends on what stays bolted to the tray permanently, not just what you carry occasionally. A tub, canopy, dual battery tray, drawer system, water tank or bullbar all add constant weight that the standard leaf pack was never rated for. Tell our team your typical accessory load and we'll confirm whether the 300kg rear leaf springs in this kit suit your setup or if a heavier-rated option is a better match.
This kit is best fitted by an experienced 4WD suspension installer or a competent DIY mechanic with a hoist and basic hand tools, given the leaf spring and U-bolt work involved. A wheel alignment is mandatory once the kit is fitted, as the 2" lift changes camber, caster and toe from factory settings. Allow a 500km bed-in period for the new springs and shocks to settle before fine-tuning tyre pressures and load. If you're running larger tyres or towing regularly, pairing this kit with upgraded control arms helps correct front-end geometry and driveline angles at the new ride height.
Dobinsons has engineered 4WD suspension in Australia for decades, valving shocks and springs around Australian roads rather than adapting an overseas set-up. Every Nitro Gas shock in this kit uses Fuchs oil and NOK seals, and the kit carries the Dobinsons manufacturer warranty backed by our fitment support team. Touring couples, remote-area travellers and tradespeople running canopies all rely on this same shock and spring combination on the Colorado RG — view the full Dobinsons suspension range for other RG-specific options.
This kit suits Colorado RG owners who tow a van or trailer, run a tray and canopy for work, or head off the black top for weekends away and need more clearance without a harsh daily ride. If your accessory load varies a lot — say a canopy some weeks and an empty tray others — it's worth comparing this constant-rate leaf spring kit against our airbag suspension options, which let you adjust support on the fly.

This kit delivers a genuine 2" lift front and rear on the Colorado RG when fitted with the standard accessory load it's rated for. Actual ride height can vary slightly depending on vehicle weight, tyre size and how much constant load is carried on the tray. Our team can confirm expected height for your specific setup before you order.
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 2 front and 2 rear Dobinsons Nitro Gas shock absorbers, 2 front 2" raised coil springs, 2 rear heavy-duty leaf spring assemblies rated to 300kg constant load, plus the U-bolts, shackles, bushes and hardware needed to fit them. Upper control arms are not included and are sold separately. Full fitting instructions are supplied with the kit.
Yes, the 300kg-rated rear leaf springs and matched Nitro Gas shocks in this kit are designed to support constant accessory and tow-ball load better than the factory leaf pack. It's a good match for Colorado RG owners towing a van or trailer regularly. Tell us your typical tow-ball weight and rear accessory load so we can confirm this spring rate is right for your setup.
A 2" lift on the Colorado RG changes front suspension geometry, so upgraded control arms are recommended rather than mandatory. Aftermarket control arms correct caster and reduce CV joint angle at the new ride height, which helps front tyre wear and steering feel. If you're running this lift long-term or with larger tyres, we'd suggest budgeting for them.
Yes, a full wheel alignment is mandatory after fitting this lift kit. The 2" lift alters camber, caster and toe from factory specification, and driving on an unaligned front end will cause uneven tyre wear. We recommend booking your alignment straight after installation, before the vehicle sees regular road use.
Dobinsons offers this RG kit with different rear leaf spring load ratings to suit varying constant accessory loads, and our team can advise which rating matches your canopy, tray or touring setup. Front coil springs are generally matched to the vehicle's standard weight distribution rather than offered in multiple rates. Contact us with your accessory list and we'll confirm the best combination before you order.
A 2" lift on the Colorado RG typically clears larger tyres than standard, though the exact size depends on your wheel offset and whether guard trimming is needed. Most owners running this kit fit up to a 33-inch tyre without major rubbing, but we'd recommend confirming your wheel and tyre combination with our team before ordering. Suspension height alone isn't the only factor — wheel width and offset matter too.
This kit is covered by the Dobinsons manufacturer warranty against defects in materials and workmanship. As an authorised Australian stockist, we handle warranty support directly rather than routing you overseas. If you have any concerns after fitment, our team is on hand to help troubleshoot before lodging a claim.
Yes, the vehicle-specific valving in the Nitro Gas shocks is tuned to keep the Colorado RG comfortable on the black top, not just off-road. Combined with the matched coil and leaf springs, ride quality stays controlled at both an unladen and loaded weight. Many owners run this exact kit as their daily driver while also using it for towing and touring on weekends.
