Selecting the correct spring rates is critical for optimal suspension performance, ride quality, and vehicle safety. Choose spring rates based on the constant accessory weight your Colorado carries permanently — not occasional loads like camping gear or temporary towing.
Front Constant Accessories: Bull bar, winch, dual battery systems, underbody protection, heavy-duty bash plates, aftermarket air conditioning, upgraded alternators, communication equipment.
Rear Constant Accessories: Aluminium or steel canopy, drawer systems and storage, long-range fuel tanks, service body or tray back, constant trade tools and equipment, dual spare wheel carriers, rear bar and tow hitch.
Occasional loads such as camping equipment, tool boxes that get removed, or towing weight should NOT be included when selecting spring rates. For vehicles that tow frequently, consider pairing this kit with airbag suspension for on-demand load adjustment.
This Dobinsons MRA lift kit requires professional installation or experienced DIY mechanical knowledge with appropriate tools and safety equipment. Installation typically takes 6-8 hours and requires spring compressors, torque wrenches, and safe vehicle lifting equipment. A professional wheel alignment is mandatory after installation to ensure correct steering geometry, tyre wear patterns, and safe handling characteristics — this is non-negotiable for lifted vehicles.
After installation, allow a 500km break-in period for springs to settle and polyurethane bushes to seat properly before making final damping adjustments. Initial ride height may be 10-15mm higher than final settled height. For vehicles with significant lift or heavy accessory loads, we recommend upgrading to heavy-duty control arms to restore correct suspension geometry and prevent premature ball joint wear.
Dobinsons provides detailed adjustment guides with each MRA kit, but our technical team is available to provide personalised damping setup recommendations based on your specific vehicle weight, accessories, and intended use.

This Dobinsons MRA Adjustable Lift Kit is engineered specifically for Holden Colorado RG 4WD models manufactured from 2012 onwards, including all Dual Cab, Extra Cab, and Cab Chassis variants. The kit fits both 2.5L and 2.8L turbo diesel engine configurations. It is NOT compatible with 2WD models or pre-2012 Colorado RC series vehicles. If you've modified your Colorado with significant accessories or have specific fitment concerns, contact our technical team with your vehicle's VIN number and we'll confirm exact compatibility and recommend appropriate spring rates for your setup.
The Dobinsons MRA kit provides approximately 2-3 inches (50-75mm) of suspension lift depending on your vehicle's current configuration, factory spring condition, and selected spring rates. Vehicles with heavy front accessories like bull bars and winches may achieve 2-2.5 inches front lift, while lighter setups may reach closer to 3 inches. Rear lift varies based on constant load — empty tray/tub configurations typically achieve 2.5-3 inches, while vehicles with canopies and drawer systems settle around 2-2.5 inches. All springs settle 10-15mm during the first 500km break-in period, so initial installed height will be slightly higher than final settled height.
This complete kit includes 4 x Dobinsons MRA adjustable monotube remote reservoir shock absorbers (2 front, 2 rear), front coil springs matched to your selected load rating, heavy-duty rear leaf springs with progressive rate design, complete U-bolt hardware kit, polyurethane bush kit, and all necessary mounting hardware and fasteners. The kit also includes detailed adjustment guides and setup instructions. Note that upper control arms, differential drop brackets, brake line extensions, and extended sway bar links are NOT included but may be recommended depending on your specific vehicle setup and intended use — our team can advise on additional components during your order.
Absolutely — the Dobinsons MRA system is one of the best suspension choices for Colorado owners who regularly tow caravans, camper trailers, boats, or work trailers. The 3-way adjustable damping allows you to increase compression damping when towing, which dramatically improves stability, reduces body roll during cornering, and eliminates the porpoising effect common with standard suspension. The remote reservoir design prevents shock fade during long towing sessions, maintaining consistent control even on corrugated roads. For ultimate towing versatility, many customers pair this MRA kit with airbag suspension in the rear, allowing on-demand ride height and load support adjustment without compromising unladen ride quality.
Control arm upgrades are not mandatory for a 2-3 inch lift on the Colorado RG, but they are highly recommended for vehicles carrying heavy front-end accessories or those used extensively off-road. Lifting the vehicle changes suspension geometry, which can increase ball joint angles and accelerate wear. Upgraded heavy-duty control arms restore optimal geometry, reduce ball joint stress, improve wheel alignment settings, and provide stronger construction for demanding use. If your Colorado has a bull bar, winch, and heavy accessories, or you frequently drive challenging off-road terrain, budget for control arm upgrades during or shortly after lift kit installation for maximum durability and performance.
Yes, professional wheel alignment is absolutely mandatory after installing any suspension lift kit — this is non-negotiable for safe vehicle operation. Lifting your Colorado changes suspension geometry, camber, caster, and toe settings beyond factory specifications. Without proper alignment, you'll experience uneven tyre wear, poor handling characteristics, steering pull, and potentially dangerous on-road behavior. A qualified suspension specialist should perform a full 4-wheel alignment after installation, adjusting all parameters to suit your lifted vehicle configuration. Most alignment shops charge $150-250 for this service, which is a small investment for proper handling, tyre life, and vehicle safety.
Yes — selecting the correct spring rates for your specific accessory loads is one of the most important decisions when purchasing this kit. Dobinsons offers multiple front coil spring rates to accommodate different bull bar and winch weights, and various rear leaf spring options for canopies, drawer systems, service bodies, and constant trade equipment. During checkout or when contacting our team, you'll need to specify your front-end accessories (bull bar type, winch yes/no, etc.) and rear constant loads (canopy, drawers, fuel tanks, service body). Our suspension experts can recommend the optimal spring combination to achieve proper ride height, comfort, and load capacity for your exact Colorado configuration.
A 2-3 inch suspension lift on the Colorado RG typically allows fitment of 31-32 inch tyres (265/70R17 to 285/70R17) with minimal or no trimming, depending on wheel offset and tyre width. More aggressive tyre sizes like 33 inches may require minor trim work to the front bumper bar and inner guard liners, particularly at full steering lock and suspension compression. Tyre fitment is affected by wheel offset, tyre brand/model (some run larger than stated size), and your specific suspension setup. We recommend conservative sizing for daily drivers and tourers — 265/70R17 or 275/65R18 are popular choices that provide improved ground clearance without sacrificing on-road manners or requiring modifications.
Dobinsons suspension products are backed by comprehensive manufacturer warranty coverage, with specific terms varying based on application and usage conditions. Typically, Dobinsons MRA shock absorbers carry a 2-year warranty against manufacturing defects, while springs are covered under separate warranty terms. Warranty coverage applies to normal 4WD usage including touring, recreational off-roading, and towing — it does not cover racing, commercial heavy-duty use beyond rated capacity, or damage from accidents and improper installation. For complete warranty details specific to this kit and your intended use, contact our team during your purchase — we'll provide full warranty documentation and registration information with your order.
Yes — one of the major advantages of the MRA adjustable system is its ability to deliver excellent daily driving comfort while still providing outstanding off-road capability when needed. Unlike fixed-rate heavy-duty suspension that rides harshly when unladen, the MRA allows you to soften compression and rebound damping for comfortable highway cruising, then firm up settings for weekend off-road adventures or when towing. Many Colorado owners run softer settings during the week for commuting and shopping, then adjust to firmer settings for weekend touring or track work. This versatility makes the MRA ideal for vehicles that serve dual purposes — daily transport and adventure vehicle — without compromise in either role.
Best Suspension Upgrade for Serious Touring
After putting this Dobinsons MRA kit through the Simpson Desert and across to the Cape, the 3-way adjustable damping has been an absolute game-changer for handling corrugations and varying loads. The remote reservoir shocks stay cool even on long washboard sections where my old setup would've faded badly. Fitted perfectly to my 2016 Colorado and the ride quality is leagues ahead of the stock suspension, especially when loaded up with water, fuel and camping gear for extended trips.(5)
Perfect Setup for Family Beach and Bush Trips
Fitted this Dobinsons adjustable lift kit to our Colorado before our last trip down to the Victorian High Country and the difference is night and day. The ride is so much smoother on corrugations now, and being able to dial in the dampening when we've got the camper loaded makes a huge difference to how the rig handles. Setup was straightforward and the quality of the components is really impressive – you can tell these are built to last.(5)
Perfect Setup for My Colorado
Finally got the Dobinsons MRA kit fitted to my 2015 Colorado and the difference is night and day. Been running it for about three months now doing beach runs and towing the camper trailer up through the High Country, and the adjustable damping really shines when you can dial it in for different loads. Ride quality on corrugations is so much better than the old setup, and the blokes at 4WD Suspension had it delivered within a few days.(5)
