Selecting the correct spring rate is critical for optimal performance, ride quality, and component longevity. When ordering, choose spring rates based on your constant accessory load only — the weight permanently fitted to your Colorado RG. Common front accessories include steel or aluminium bullbars (25-40kg), winches (30-45kg), upgraded batteries, and long-range fuel tanks. Rear constant loads include aluminium canopies or steel service bodies (70-150kg), drawer systems (40-80kg), dual battery setups, fixed water tanks, and permanently mounted toolboxes. Occasional loads such as camping gear, passengers, tools, or towing a caravan or camper trailer should not be included in spring rate selection — these are best managed with airbag suspension for adjustable load support. Selecting an unnecessarily heavy spring rate will result in harsh ride quality, accelerated wear on bushes and ball joints, and reduced articulation on technical terrain.
Professional installation by an experienced 4WD suspension workshop is strongly recommended to ensure correct fitment, torque specifications, and safety compliance. The pre-assembled front struts simplify installation compared to traditional separate component kits, but specialised tools and knowledge are required for safe removal and fitting. A full four-wheel alignment is mandatory after installation to restore factory geometry, prevent uneven tyre wear, and ensure optimal handling and steering feel. Allow a 500km break-in period for springs to settle and bushes to seat correctly before checking and adjusting ride height or re-torquing components. For vehicles with significant constant loads or those regularly tackling extreme terrain, consider pairing this lift kit with upgraded heavy-duty control arms to restore caster angle and improve steering stability.

Yes, this kit is specifically engineered for all Holden Colorado RG models from 2012 to 2020, including dual cab, space cab, and cab chassis variants with both 2.5L and 2.8L turbo diesel engines. The kit fits 2WD and 4WD configurations equally, with pre-assembled struts and matched components designed precisely for the RG chassis geometry. If you've fitted aftermarket accessories like bull bars, winches, or heavy canopies, you'll need to select appropriate spring rates during ordering to match your constant load. Our team can confirm fitment for your specific build configuration and recommend compatible spring rates — simply contact us with your vehicle details and accessory list.
This Dobinsons kit delivers a genuine 2 inch (50mm) lift at both front and rear, measured from factory ride height with no load. This lift height provides clearance for tyres up to 32 inches in diameter without rubbing during full articulation, though minor trimming of plastic inner guards may be required depending on wheel offset and tyre width. The increased ride height also improves approach, departure, and ramp-over angles for tackling steep terrain, creek crossings, and rocky tracks. Keep in mind that final ride height will vary slightly based on your constant accessory load and selected spring rates — heavier constant loads will reduce net lift by 10-20mm as springs compress under weight.
The kit includes everything needed for a complete front and rear suspension upgrade: two pre-assembled Dobinsons IMS monotube front struts with matched coil springs and new strut top mounts, two Dobinsons IMS monotube rear shock absorbers, and two 2-inch extended greasable rear shackles. The front struts arrive fully assembled from the factory, eliminating the need for dangerous spring compression during installation. All necessary mounting hardware is included, along with Dobinsons installation documentation and warranty information. This kit does not include upper control arms, which may be recommended if you're running heavy constant loads or want to optimize caster angle after lift installation.
Yes, the Dobinsons IMS monotube technology and upgraded spring rates significantly improve towing stability, control, and safety compared to worn factory suspension. The gas-charged monotube shocks resist fade under sustained loads and provide consistent damping when towing heavy caravans or camper trailers, reducing rear-end sway and bounce. However, spring rate selection should be based on your constant accessory load only — not occasional towing weight. For optimal towing performance and the ability to adjust ride height based on trailer weight, we strongly recommend pairing this lift kit with airbag suspension, which allows you to increase rear spring rate on-demand when towing and return to comfortable ride quality when unladen.
Control arm upgrades are not strictly required for a 2-inch lift, but they are highly recommended if you're running heavy constant front loads (bullbar and winch) or regularly tackle serious off-road terrain. Lifting the Colorado RG by 2 inches alters the suspension geometry slightly, which can reduce caster angle and affect steering feel and stability at highway speeds. Upgraded heavy-duty control arms with corrected geometry restore optimal caster, improve steering response, and provide stronger ball joints and bushes for heavy-duty use. If your Colorado is primarily a daily driver with light off-road use, the factory control arms will function adequately; for serious touring rigs or work vehicles, upgraded arms are a worthwhile investment.
Yes, a professional four-wheel alignment is absolutely mandatory after installing any lift kit, including this Dobinsons system. Lifting your Colorado RG changes suspension geometry and alters toe, camber, and caster angles beyond factory specifications, which will cause rapid uneven tyre wear, poor handling, and wandering steering if not corrected. A full alignment restores these angles to optimal settings for your new ride height, ensuring safe handling, maximum tyre life, and confident steering feel both on-road and off. Most reputable 4WD suspension workshops will include alignment as part of their installation service. Never skip this critical step — the cost of premature tyre wear far exceeds the alignment cost.
Spring rate selection must be based exclusively on your constant accessory load — the weight permanently fitted to your vehicle that you carry every day. Measure or estimate the weight of front accessories (bullbar, winch, heavy-duty batteries, auxiliary lights) and rear accessories (canopy or tray, drawer systems, fixed water tanks, toolboxes). Do not include occasional loads such as camping gear, passengers, esky contents, or towing weight when selecting spring rates, as these vary trip to trip. Dobinsons offers multiple spring rate options from light (factory accessories only) through medium (typical touring setup) to heavy (full trade fitout). Selecting springs that are too heavy for your actual constant load will result in harsh ride quality, reduced articulation, and accelerated wear on bushes and ball joints.
With a 2-inch lift, most Holden Colorado RG owners can comfortably fit tyres up to 32 inches in diameter (265/70R17 or 265/65R18) without any rubbing during full lock steering or suspension compression. Depending on your wheel offset and tyre width, you may need to perform minor trimming of inner guard plastic or mudflap brackets to prevent contact at full articulation. Tyres beyond 32 inches (such as 285/70R17 or 33-inch equivalents) will typically require additional modifications including guard trimming, diff drop brackets, or moving to a 3-inch lift kit. Keep in mind that larger, heavier tyres affect gearing, fuel economy, and braking performance — always ensure your spring rates are matched to the additional unsprung weight of larger wheel and tyre packages.
Dobinsons backs this IMS Quick Lift Kit with a comprehensive manufacturer warranty covering defects in materials and workmanship, giving you confidence in the quality and durability of your investment. Specific warranty terms vary by component — shock absorbers and struts typically carry a 3-year or 60,000km warranty (whichever occurs first), while springs and hardware have separate coverage periods. Warranty coverage requires professional installation by a qualified workshop with proof of purchase and service records. Dobinsons has an extensive dealer and service network across Australia, making warranty claims and component replacement straightforward even when you're touring remote regions. Contact 4WD Suspension or check your included warranty documentation for complete terms and conditions.
This IMS Quick Lift Kit is absolutely suitable for daily driving and in fact excels at balancing on-road comfort with off-road capability. Dobinsons engineers these kits specifically for dual-purpose vehicles that serve as weekday commuters and weekend adventurers, providing a ride quality that remains comfortable on sealed roads, highways, and around town. The IMS monotube technology delivers controlled damping that absorbs highway undulations and urban potholes without harshness, while still maintaining the performance needed for corrugated tracks, sand, and rocks. Many Colorado RG owners run this kit on vehicles that see 80% road use and 20% off-road use, reporting that ride quality actually improves over worn factory suspension. If your Colorado is a dedicated work vehicle carrying heavy loads daily, you'll especially appreciate the upgraded load-carrying capability and reduced body roll.
Perfect Upgrade for Our Touring Colorado
After 18 months travelling the outback with the van in tow, this Dobinsons lift kit has completely transformed our Colorado's handling on corrugated roads. The pre-assembled struts made installation straightforward at our local workshop in Townsville, and we were back on the road within a day.
