The Dobinsons Nitro Gas 2" Lift Kit suits the Holden Colorado RC (2008-2012) and pairs twin-tube nitro gas shocks with 2" raised rear leaf springs, while front lift is set via the factory torsion bar keys. Larger bore shocks with increased oil capacity handle heat better than stock units, and polyurethane bushings tighten up handling under load. This lift kit suits tourers and tradies running a steady accessory load. In stock in Australia, backed by a Dobinsons manufacturer warranty and our fitment support team.

Choosing the right rear leaf spring rate depends on the constant accessory weight your Colorado RC carries day to day, not just occasional loads. A tray-back with a steel canopy, dual battery tray, long-range fuel tank or bullbar and winch combination all add constant load that a standard-rated spring wasn't designed for. If your build is heavier than average, contact our team before ordering so we can check whether a firmer Dobinsons leaf spring option suits your setup better than the standard rate supplied in this kit.
Fitting this kit involves adjusting the front torsion bar keys and replacing the rear leaf springs and shocks, so it's best handled by a qualified suspension fitter or an experienced DIY mechanic with the right tools. A full wheel alignment is mandatory once the kit is installed, as ride height and suspension geometry both change. Allow a 500km break-in period for the new shocks and springs to settle before fine-tuning torsion bar height further. If you're correcting geometry at the new ride height, it's worth reviewing our control arm upgrades at the same time.
Dobinsons has manufactured 4WD suspension in Australia for over 60 years, with shocks and springs designed and tested locally for Australian roads and conditions. Every kit is backed by a manufacturer warranty, and Dobinsons components are widely used by tourers, tradespeople and fleet operators running Colorado RC utes. You can view the full Dobinsons range to compare shocks, springs and accessories for your vehicle.
This kit suits Colorado RC owners who need a 2" lift for larger tyre clearance combined with genuine load-carrying ability — tradespeople running canopies and toolboxes, and tourers fitting drawer systems, bullbars or rooftop tents. If your accessory load varies significantly trip to trip, our airbag suspension options can be added to this kit for adjustable load support on demand.

Yes — this kit is designed specifically for Holden Colorado RC models built 2008 to 2012, covering both the 3.0L turbo-diesel and 3.6L V6 petrol variants. Confirm your build date and engine using our parts finder or contact our team before ordering. Front lift is set by adjusting the factory torsion bar keys, and rear lift comes from the 2" raised leaf springs. If you already run a bullbar, canopy or towbar, let us know so we can check for clearance at the new ride height.
This kit delivers a genuine 2" lift at the front, achieved by winding up the factory torsion bars, and a 2" lift at the rear from the raised leaf springs. Actual ride height gain can vary slightly depending on accessory load and tyre size fitted. The nitro gas shocks are valved to suit this lift height for correct droop and compression travel. Contact us if you're after a different front-to-rear lift split for your Colorado RC.
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 twin-tube shock absorbers, 2 raised rear leaf springs rated for constant load, and a rear U-bolt kit. Poly bushings for the shock mounts and greasable shackle bushes for the leaf spring assembly are also included. Front lift uses the existing factory torsion bars adjusted to the new height rather than replacement springs. Fitting instructions are supplied, and control arms are sold separately if required.
Yes. The rear leaf springs in this kit are rated for constant load, suiting a Colorado RC running a canopy, tool boxes, or a loaded tow ball weight. The larger bore nitro gas shocks with increased oil capacity manage the extra heat generated when towing on longer trips. If your combined accessory and towing load is heavier than average, talk to our team about a firmer rear spring rate before ordering. Your Colorado RC's towbar and axle ratings from Holden still apply and aren't increased by this kit.
A 2" lift on a Colorado RC doesn't always require new front control arms, but correcting CV and steering geometry with upgraded units can improve ball-joint angles and CV life at this ride height. Many owners fit control arms at the same time as this lift kit to reduce long-term wear. Speak with our team about your intended use — daily driving versus loaded off-road touring — before you decide.
Yes, a full four-wheel alignment is mandatory after installing this kit. Ride height changes with any lift, and camber, caster and toe need resetting to Holden Colorado RC specification. Skipping alignment leads to uneven tyre wear and can affect steering feel. Book your alignment as soon as the kit is fitted, ideally after the 500km break-in period.
This kit is supplied with a standard constant-load rated rear leaf spring suited to typical touring and light towing setups. If you're running a heavier canopy, dual battery system, or bullbar and winch combination, contact our team — Dobinsons offers other leaf spring rate options across the Colorado RC leaf spring range. Getting the rate right prevents sagging and keeps the vehicle sitting level under your actual load.
A 2" lift front and rear on a Colorado RC typically opens up clearance for a modest tyre size increase over stock, though exact clearance depends on wheel offset and width. We recommend confirming your intended tyre and wheel combination with our team before you order. Always check for rubbing at full steering lock and full suspension compression after fitment.
This kit is covered by a Dobinsons manufacturer warranty against defects in materials and workmanship. Dobinsons has manufactured 4WD suspension components in Australia for over 60 years. Keep your proof of purchase and installation date on file, and contact our team directly if you ever need to make a warranty claim.
Yes. The twin-tube nitro gas shock design in this kit is tuned to balance comfort on sealed roads with control when the vehicle is loaded or on unsealed surfaces. Many Colorado RC owners run this kit as their daily commuter as well as their weekend touring setup. Ride quality will feel firmer than stock when unladen until the vehicle is carrying its usual working load.
