The Dobinsons MRA Adjustable Lift Kit suits the Holden Colorado RG (2012 on) and delivers a selectable 2" or 3" lift with 3-way externally adjustable remote-reservoir shocks front and rear. Vehicle-specific coil springs and leaf spring options let you match rear spring rate to your constant accessory load for touring or towing. This adjustable lift kit uses a monotube shock design for consistent damping on corrugations and rough tracks. In stock in Australia with manufacturer warranty and fitment support from our team.

Lift height compliance: Suspension lifts of this size may exceed your state's allowable limit without engineering certification. Check your state's light vehicle modification rules (VSB14/NCOP) before fitting.
Choose your rear leaf spring rate based on what you carry permanently, not just what you carry occasionally. The 300kg option suits a Colorado RG running a steel tray or light canopy, while the 480kg option suits a heavier tray, canopy with drawers, water tank or a permanently mounted camper. Front coil rate is matched to a bullbar and winch combination — tell our team your front accessory weight so the correct spring is supplied.
Fitment should be carried out by an experienced 4WD suspension workshop or a competent DIY installer with access to a hoist and spring compressors. A wheel alignment is mandatory after fitting to bring camber, caster and toe back within factory tolerance at the new ride height. Allow a 500km break-in period for the springs to settle and the shock bushes to seat before final alignment. For correct front geometry at 2" or 3" of lift, pair this kit with control arm upgrades to restore CV angles and steering geometry.
Dobinsons has built 4WD suspension for the Australian aftermarket for decades, with springs and shocks developed and tested locally for local roads and loads. Every MRA shock and Dobinsons spring in this kit carries a manufacturer warranty, and the brand is used regularly by tourers, tradespeople and remote-area travellers who need reliable, serviceable componentry. You can view the full Dobinsons range for other Colorado-compatible parts.
This kit suits Colorado RG owners running a bullbar, winch, canopy or caravan who need adjustable damping to match a variable load. It's a good fit for tradespeople carrying tools daily and tourers loading up for extended trips. If your load varies significantly trip to trip, also consider airbag suspension to fine-tune rear ride height on the fly.

This Dobinsons MRA kit is built specifically for the Holden Colorado RG built from 2012 onwards, covering both 2.5L and 2.8L TD Duramax variants. It is not a universal kit — the coil and leaf spring rates are matched to this chassis. If you're unsure of your exact build date or variant, our team can confirm fitment before you order.
The kit provides a selectable 2" or 3" lift front and rear, set by the spring combination chosen at the time of order. Front lift comes from vehicle-specific coil springs and rear lift from the leaf spring pack fitted. Tell us your preferred height and accessory load and we'll confirm the correct spring rate.
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 MRA adjustable remote-reservoir shocks, front coil springs, rear leaf springs in your chosen load rating, U-bolts, greasable shackles and bushes, and fitting instructions. Upper control arms are not included and are sold separately. See the full kit contents list on this page for exact quantities.
Yes, this is a common reason customers choose this kit. The rear leaf springs are available in a 300kg or 480kg constant load rate, letting you match spring rate to a tow ball weight or loaded canopy. The 3-way adjustable remote-reservoir shocks also let you firm up damping when towing and soften it when unladen.
We recommend it. At 2" or 3" of lift the factory control arm geometry is compromised, which can affect CV joint angles and camber. Upgraded control arms correct this geometry and reduce wear on CV joints and bushes. See our control arm range for Colorado RG-compatible options.
Yes, wheel alignment is mandatory after installing this kit. Ride height changes camber, caster and toe, and factory alignment settings will be out of specification. We recommend an alignment immediately after fitting and again after the 500km spring break-in period.
Yes. Rear leaf springs are available in a 300kg or 480kg constant load rating to suit your typical rear accessory weight, such as a tray, canopy, water tank or drawer system. Front coil springs are matched to your bullbar and winch weight. Tell our team what you're carrying and we'll recommend the correct combination.
A 2" to 3" lift on the Colorado RG typically clears larger tyre sizes than standard, but exact clearance depends on tyre width, wheel offset and whether flares are fitted. We recommend confirming your intended tyre size with our team before ordering so we can advise on any additional trimming needed.
This kit is covered by Dobinsons' manufacturer warranty on both shocks and springs. We also provide fitment support from our Australian team if you have questions before, during or after installation. Keep your invoice as proof of purchase for any warranty claim.
Yes. The 3-way external damping adjustment lets you dial in a softer setting for daily driving and unladen use, then firm it up for towing or off-road work. Many Colorado RG owners run this kit as their daily driver while still using it for weekend touring or towing.
