Selecting the correct spring rate is critical for achieving optimal ride quality, load capacity, and suspension longevity in your Colorado RG. When ordering, you must specify front coil and rear leaf spring rates based on your constant accessory load only — this means weight that remains on the vehicle permanently such as bull bars, winches, canopies, drawers, dual battery systems, long-range fuel tanks, roof racks with permanent loads, and heavy-duty tow bars. Occasional loads like camping gear, tools, towing loads, and passengers should NOT be factored into your spring rate selection as over-rating your springs will result in harsh ride quality and potential damage to other suspension components when driving unladen.
Common Front Accessories: Steel bull bar (30-60kg), winch (30-50kg), upgraded bar with winch combo (60-100kg), aftermarket bumper systems, heavy-duty radiator protection, driving lights and auxiliary battery systems.
Common Rear Accessories: Aluminium canopy (60-80kg), steel canopy (80-120kg), drawer systems (40-80kg), dual spare wheel carriers (40-60kg), long-range fuel tanks (when full 60-100kg additional), tub liners, sports bars, and permanently mounted storage solutions.
Professional installation by a qualified 4WD suspension specialist is strongly recommended to ensure correct fitment, adjustment, and safety compliance. Experienced DIY installers with appropriate tools, spring compressors, and workshop facilities can complete installation, though professional setup ensures optimal performance and warranty coverage. A full four-wheel alignment is mandatory after installation to prevent premature tyre wear and ensure proper steering geometry — camber, caster, and toe settings must all be readjusted to manufacturer specifications for lifted ride height.
After installation, a 500km break-in period allows springs to settle and shocks to bed in — ride height may drop 5-10mm during this period which is normal. Many Colorado RG owners also upgrade to heavy-duty control arms when lifting to maintain optimal suspension geometry, improve articulation, and add castor correction for better highway stability and steering feel.
Dobinsons has been Australia's trusted suspension brand for over 60 years, with a legendary reputation built on outback testing, engineering excellence, and real-world performance across the harshest terrain on earth. Every Dobinsons component is designed specifically for Australian conditions and tested by Australian tourers, tradespeople, and off-road enthusiasts who demand reliability when hundreds of kilometres from help. Comprehensive warranty coverage and Australia-wide dealer support network provide peace of mind whether you're crossing the Simpson or commuting to work — explore the complete Dobinsons suspension range engineered for serious 4WD performance.
This adjustable monotube lift kit is ideal for Holden Colorado RG owners who demand premium performance across mixed driving conditions — from daily commuting and highway touring to serious remote area exploration and regular towing. Tradespeople carrying tools and equipment, touring families with roof-top tents and camping gear, and caravan towers will appreciate the adjustable height capability and custom spring rates that maintain ride quality under varying loads. If you frequently carry heavy loads or tow close to GVM limits, consider pairing this kit with airbag suspension for additional load support and on-demand ride height adjustment.

This Dobinsons Monotube IFP Adjustable Height Lift Kit is specifically engineered for Holden Colorado RG models from 2012 to 2020, covering all body styles including Single Cab, Space Cab, and Crew Cab variants. The kit fits both 2WD and 4WD configurations with factory suspension setups. If you've already modified your Colorado with aftermarket components like lifted diff housings or non-standard suspension mounts, please contact our team to confirm compatibility. Use our parts finder tool or reach out to our suspension specialists for personalised fitment confirmation based on your vehicle's build date and current modifications.
This Dobinsons kit provides approximately 40mm (1.6 inches) of rear lift from the raised leaf springs, with front lift achieved through the combination of raised coil springs and adjustable height shock absorbers — typically delivering 30-40mm front lift depending on constant accessory load and spring rate selected. The adjustable height feature on both front and rear shocks allows you to fine-tune ride height within a range to suit different load configurations. Final settled ride height will stabilise after the recommended 500km break-in period as springs settle and components bed in. Actual lift may vary based on your specific vehicle weight, accessory loads, and spring rate selection.
This complete kit includes 2 x Dobinsons monotube IFP adjustable front shock absorbers, 2 x front coil springs in your selected spring rate, 2 x monotube IFP adjustable rear shock absorbers, 2 x 40mm raised rear leaf springs in your selected spring rate, 4 x heavy-duty U-bolts with hardware, and 1 x polyurethane bush kit. All necessary mounting hardware and components for a complete installation are provided. Upper control arms, extended brake lines, diff drop kits, and wheel alignment are not included but may be required or recommended depending on your specific setup — our team can advise on complementary components during your order.
Yes, this Dobinsons monotube lift kit is excellent for towing applications when correctly configured with appropriate spring rates for your constant load. The monotube IFP shock absorbers provide superior heat dissipation and fade-resistant damping control even under the stress of heavy towing, while the adjustable height feature allows you to compensate for tow ball weight. For optimal towing performance, ensure you select spring rates based only on your permanent accessory weight, not towing loads. Many Colorado towers also add airbag suspension for additional load support and the ability to level the vehicle when hitched — contact us for a complete towing suspension package recommendation.
While not absolutely mandatory for a 40mm lift, upgrading to heavy-duty aftermarket control arms is highly recommended for the Holden Colorado RG to maintain optimal suspension geometry, improve wheel alignment parameters, and add castor correction for better highway stability. Lifted vehicles can experience changes in camber and castor angles that affect tyre wear and steering feel, which adjustable control arms help correct. Heavy-duty control arms also provide stronger mounting points, better articulation off-road, and improved durability under the increased loads of touring and towing. Our suspension specialists can recommend compatible control arm options that perfectly complement this Dobinsons lift kit for your specific driving needs.
Yes, a full four-wheel alignment is absolutely mandatory after installing any lift kit on your Holden Colorado RG. Lifting the vehicle alters suspension geometry including camber, castor, and toe angles, which if left uncorrected will cause rapid and uneven tyre wear, poor steering response, and potential safety issues. Your alignment technician should set all parameters to manufacturer specifications adjusted for the new ride height, which may require adjustable control arms to achieve correct castor angle. The alignment should be performed after installation but ideally rechecked again after the 500km break-in period once springs have fully settled to their final height.
Spring rate selection must be based solely on your constant accessory load — permanent weight that stays on the vehicle at all times such as bull bars, winches, canopies, drawer systems, dual batteries, and long-range fuel tanks. Do not include occasional loads like camping gear, passengers, tools, or towing weight in your calculation, as this will result in over-sprung suspension that rides harshly when unladen. Weigh your front and rear axles separately with all permanent accessories fitted, compare to factory weights, and select spring rates accordingly. Our team can provide detailed spring rate recommendation based on your specific accessory list — providing accurate information ensures optimal ride quality and suspension longevity.
With approximately 40mm of lift, most Holden Colorado RG owners can comfortably fit 32-inch tyres (265/70R17 or 265/65R18) with minimal to no rubbing under full compression and steering lock. Some owners successfully run 33-inch tyres (285/70R17 or 285/65R18) with minor trimming of plastic guards and potentially aftermarket offset wheels. Tyre fitment depends on multiple factors including wheel offset, tyre brand profiles, suspension compression under load, and whether you've added diff drops or other modifications. We recommend test fitting with full steering lock and suspension compression before committing to larger tyres, and remember that significantly larger tyres may require speedo recalibration and can affect gearing, fuel economy, and brake performance.
Dobinsons provides comprehensive warranty coverage on all components in this lift kit, with shock absorbers typically covered by manufacturer warranty against defects in materials and workmanship. Springs are also warranted against sag and breakage under normal operating conditions. Specific warranty terms and duration vary by component type, so please refer to the included Dobinsons warranty documentation or contact our team for detailed warranty information. Warranty coverage requires professional installation or proof of correct DIY installation, use of components within rated capacity, and proper vehicle maintenance. Dobinsons' extensive Australian dealer network ensures warranty support across the country for peace of mind on remote touring adventures.
Absolutely — the Dobinsons monotube IFP technology is specifically designed to deliver exceptional on-road comfort while maintaining off-road capability. The Internal Floating Piston design provides smoother, more consistent damping than traditional twin-tube shocks, resulting in excellent highway ride quality, reduced body roll in corners, and stable, controlled handling during daily commuting and long-distance touring. When correctly configured with appropriate spring rates for your load, this kit provides a comfortable ride that's noticeably smoother than factory suspension while offering the ground clearance and durability needed for weekend off-road adventures. The adjustable height feature also allows you to fine-tune ride characteristics for your specific driving preferences and load conditions.
Proper Kit for Remote Outback Work
Been running this Dobinsons IMS kit on my Colorado for about 8 months now, covering everything from the Simpson Desert to Cape York during the wet. The adjustable monotube shocks handle corrugations and rock sections far better than the old setup, and the ride quality loaded up with gear and water is genuinely impressive. Worth every cent if you're serious about getting remote.(5)
Perfect Upgrade for Our Family Adventures
Had the Dobinsons IMS kit fitted to our Colorado before our last trip down to Wilsons Prom and the difference is night and day. The adjustable shocks let me dial in the perfect ride height whether we're loaded up with camping gear or running light, and the kids aren't complaining about the bumpy corrugations anymore. Really impressed with how well everything's holding up after a few months of regular use – you can tell it's quality gear that's actually designed for our conditions.(5)
Best upgrade I've done to the Colorado
Had the Dobinsons IMS kit fitted to my RG Colorado about three months back and it's been ripper. Daily commute to sites is way more comfortable than the old setup, and took it down the beach at Stockton last weekend - handled the soft sand no worries with the extra clearance. The adjustable shocks are mint for when I'm loaded up with tools and gear during the week, honestly should've done it sooner.(5)
Solid Setup for Serious Remote Travel
Been running this Dobinsons IMS kit on my Colorado for about 8 months now, including some pretty rough tracks through the Simpson Desert and Cape York. The adjustable monotube shocks handle corrugations brilliantly and I've been able to fine-tune the setup for different load configurations when we're carrying extra fuel and water for extended trips. Build quality is excellent and the ride is far more controlled than the previous setup, especially when loaded up.(5)
Perfect Setup for Our Family Adventures
We've done three camping trips up the coast since fitting this Dobinsons kit to our Colorado and the difference is night and day. The adjustable shocks let me dial in the perfect height whether we're loaded up with gear or running light, and the kids reckon the corrugated roads don't rattle their teeth anymore. Installation was straightforward with all the hardware included, and the monotube setup handles our camper trailer beautifully without any of that wallowing we used to get.(5)
