Selecting the correct spring rate is critical for ride quality, safety, and component longevity. When ordering, choose the spring rate based on your current constant load — the accessories and equipment permanently fitted to your Colorado's front end. Common front accessories include steel bullbars (25-45kg), winches (30-50kg), larger batteries, dual battery systems, intercooler upgrades, heavy-duty radiators, and driving lights. Occasional loads such as camping gear or towing (which affects rear suspension primarily) should NOT be considered when selecting front spring rates. Selecting overly heavy springs for loads you don't carry constantly will result in harsh ride quality and potential damage to bushings and other suspension components.
This front lift kit is designed for professional installation or experienced DIY mechanics with appropriate spring compressor tools and safety equipment. A full four-wheel alignment is mandatory after installation to ensure correct castor, camber, and toe settings — preventing premature tyre wear and maintaining steering feel. Allow a 500km break-in period for springs to settle and bushings to seat properly before final ride height is achieved. For Colorado RG models with significant lift (50mm+) or heavy bullbar/winch setups, consider pairing this kit with upgraded control arms to restore suspension geometry and improve handling.
With over 60 years of Australian manufacturing heritage, Dobinsons Spring & Suspension is trusted by touring families, tradespeople, and commercial fleet operators across Australia and 40+ countries worldwide. Every shock absorber undergoes rigorous in-house dyno testing, durability cycling, and real-world validation in conditions ranging from the Simpson Desert's corrugations to Tasmanian alpine trails. Dobinsons backs this kit with comprehensive warranty coverage and is engineered to ISO/TS16949 quality standards using state-of-the-art robotic welding and CNC machining. Explore the complete Dobinsons suspension range for matched front and rear solutions.
This kit is ideal for Holden Colorado RG owners who've fitted a steel bullbar and winch, need to restore ride height lost to accessories, or want improved towing stability and load-carrying capability. Tradespeople running toolboxes and equipment will appreciate the firmer valving and increased payload support, while touring families towing caravans benefit from reduced front-end sag and better headlight aim control. If you regularly carry extreme rear loads or tow near GVM limits, consider adding airbag suspension to the rear for on-demand load adjustment and level towing.

Dobinsons engineers each shock absorber and strut assembly using advanced CAD design, finite element analysis, and real-world testing protocols that simulate extreme Australian conditions. Every component is validated through millions of compression and rebound cycles on custom-built durability testers, with operating temperatures exceeding 100°C to ensure fade-free performance under sustained heavy use. In-house dyno testing measures valve forces at varying velocities, ensuring each strut delivers precise damping characteristics matched to the Holden Colorado RG's weight distribution, spring rates, and intended use cases. This obsessive attention to detail results in suspension components that outperform OEM equipment in every measurable category — from heat dissipation to seal longevity.
Dobinsons sources only the highest-grade internal and external components from specialized global suppliers. Japanese NOK multi-lip seals are renowned for preventing oil migration in extreme temperature swings and contaminated environments. Premium Fuchs German shock oil maintains consistent viscosity from subzero alpine mornings to blistering outback afternoons. High-quality Teflon piston rings ensure minimal friction and wear over hundreds of thousands of kilometers. The double-chromed 18mm hardened rod resists pitting and corrosion far better than lesser finishes, while natural rubber bushings reduce noise and vibration without the premature deterioration common with cheaper polyurethane alternatives. Thicker external tube wall construction — up to 3mm on selected struts versus 1.5mm on budget brands — provides structural integrity when subjected to side loads and impacts.
Every Dobinsons strut assembly is manufactured to ISO/TS16949 International Quality Assurance Systems using state-of-the-art automated processes. Double-reinforced robotic welding ensures consistent, void-free seam strength. Friction welding of mounting stems creates molecular bonds stronger than the parent materials. CNC machined components maintain tolerances measured in hundredths of millimeters for perfect piston-to-bore clearances. Drop-forged mounting stems on selected applications provide superior strength compared to cast or machined alternatives. This manufacturing excellence, combined with rigorous quality sampling and batch testing, ensures every strut leaving Dobinsons' facility meets the exacting standards required for Australian commercial, touring, and recreational 4WD use.
This kit is specifically engineered for all Holden Colorado RG models from 2012 to 2020, including both 2.5L and 2.8L diesel variants. The pre-assembled struts are direct OEM replacements requiring no modifications for fitment. If you have a Colorado RG7 (2017-2020 facelift model) or earlier RG (2012-2016), this kit fits both series perfectly. For confirmation of fitment or questions about compatibility with aftermarket suspension modifications already fitted to your vehicle, contact our technical team who can verify compatibility with your specific build.
Lift height achieved depends on your current front-end accessory load and the spring rate selected at checkout. For a Colorado RG with a standard steel bullbar and winch (approximately 60-80kg front load), expect 30-50mm of lift over factory ride height when appropriate medium-duty springs are selected. If you have a lightweight alloy bullbar or no bullbar, lighter springs will provide similar lift with better ride quality. The kit is designed to restore factory ride height when accessories are fitted, or provide moderate lift for unladen vehicles. Final settled height is achieved after the 500km break-in period as springs settle and bushings seat.
This kit includes two complete pre-assembled Dobinsons Nitro Gas front struts with coil springs already fitted, ready to bolt into your Colorado RG. Each strut features premium NOK seals, Fuchs German oil, natural rubber bushings, and steel dust covers where applicable — all factory assembled and nitrogen charged. The kit does NOT include rear suspension components, upper control arms, extended brake lines, diff drop spacers, or installation hardware beyond what's integrated into the strut assemblies. You'll need to reuse your existing top mounts and hardware unless ordering separate upgrade components. Professional installation and wheel alignment are required but not included.
Yes, this front lift kit significantly improves towing stability and performance by restoring proper front-end geometry and providing firmer damping than worn factory struts. The vehicle-specific valving controls weight transfer during braking and reduces front-end dive when towing heavy loads. However, towing primarily affects rear suspension — tongue weight from caravans compresses the rear, not the front. For optimal towing setup, pair this front kit with upgraded rear leaf springs or airbag suspension for the rear axle. The firmer front damping works synergistically with properly rated rear suspension to maintain level vehicle attitude and predictable handling when towing at or near your Colorado's rated towing capacity.
For moderate lift heights (30-50mm) achieved with this front strut kit, upgraded control arms are not mandatory but are highly recommended if you have a heavy bullbar/winch combination or plan to fit larger tyres. The factory upper control arms on the Colorado RG have limited adjustment range — significant lift can push castor and camber angles outside ideal specifications even after professional alignment. Upgraded adjustable control arms restore correct suspension geometry, improve steering feel, reduce tyre scrub, and provide better wheel clearance for larger tyres. If you're lifting more than 40mm or running 32-inch-plus tyres, budget for quality aftermarket control arms as part of your complete suspension upgrade to maximize handling, safety, and tyre life.
Yes, a full four-wheel alignment is absolutely mandatory after installing any suspension lift kit, including this Dobinsons front strut assembly. Lifting the front end changes castor, camber, and toe angles from factory specifications — even small deviations cause rapid tyre wear, poor steering feel, and reduced handling safety. A professional alignment ensures all angles are returned to manufacturer specifications (or optimized performance settings if using adjustable components). Book alignment with a shop experienced in 4WD suspension work who can accommodate lifted vehicles. Allow the suspension to settle for 500km of normal driving before performing a final alignment check, as springs compress slightly during the break-in period and angles may shift marginally from initial settings.
Yes, spring rate selection is critical when ordering this kit, and you must select the rate matching your current constant front-end accessory load. Dobinsons offers multiple spring rates calibrated for different weight ranges — from unladen vehicles to those carrying heavy steel bullbars, winches, dual battery systems, and other permanent accessories. During checkout, you'll select front spring rate based on your total front accessory weight. Accurately calculate the combined weight of your bullbar, winch, driving lights, upgraded intercooler, heavy-duty battery setup, and any other permanently mounted equipment. Do NOT select heavier springs anticipating occasional loads or camping gear — this causes harsh ride quality and accelerated wear on bushings and suspension components. Contact our team if you need assistance calculating your front accessory weight for optimal spring selection.
This front lift kit provides clearance for modestly larger tyres, but total tyre size depends on combined front and rear lift, wheel offset, and whether you've fitted aftermarket control arms or guard trimming. With 40mm of front lift from this kit (and matched rear lift), most Colorado RG owners can fit 265/70R17 or 265/65R18 tyres without rubbing, representing approximately a 1-inch diameter increase over stock. For 285-width tyres or 32-inch-plus diameters, you'll likely need wheel spacers or negative offset wheels, possible guard trimming, and definitely upgraded control arms for clearance at full lock and suspension compression. Tyre fitment is highly dependent on wheel specifications and exact lift achieved — consult with a reputable tyre and suspension specialist who can test-fit before purchasing tyres to avoid costly returns or clearance issues.
Dobinsons backs this Nitro Gas front strut kit with comprehensive manufacturer warranty coverage against defects in materials and workmanship. Warranty terms vary by component and application — shock absorbers and struts typically carry 12-24 month warranty depending on use case, while coil springs are covered separately. Warranty coverage requires professional installation by a qualified mechanic, adherence to recommended service intervals, and operation within the product's rated load capacity. Warranty does NOT cover wear items, damage from accidents or misuse, or failures resulting from improper installation or vehicle modifications exceeding component ratings. Retain your proof of purchase and installation records. For specific warranty terms and claim procedures, contact 4WD Suspension Australia or refer to the Dobinsons warranty documentation included with your kit.
Absolutely — this Dobinsons Nitro Gas front kit is engineered to deliver excellent ride quality for daily driving while providing the durability and load capacity needed for touring and off-road use. The twin-tube design with natural rubber bushings reduces noise, vibration, and harshness compared to monotube or polyurethane-bushed alternatives. Vehicle-specific valving ensures controlled damping without the harsh, jarring ride quality associated with cheap lift kits or overly stiff competition-oriented suspension. Thousands of Australian Colorado owners use Dobinsons suspension for daily commuting, school runs, and highway driving while maintaining capability for weekend touring, boat launching, and recreational off-roading. When correct spring rates are selected for your accessory load, this kit provides a comfortable, compliant ride that's noticeably better than worn factory suspension while transforming capability when you need it.
Perfect Upgrade for Our Family Tourer
Fitted these Dobinsons struts to our Colorado before our last trip down to Wilsons Prom and the difference is night and day. The front end sits level now even with the camping gear and roof tent loaded up, and the ride quality is surprisingly comfortable on both highway and corrugated tracks. Really impressed with how well-engineered these are for Australian conditions – you can tell they've been properly designed for our roads and the sort of weight we carry when heading bush with the family.(5)
Best upgrade I've done to the Colorado
Threw these Dobinsons front struts on my 2015 Colorado and the difference is night and day. The ride is so much smoother now even with tools and materials in the back, and it's sitting level instead of sagging at the front. Dead easy install too, being pre-assembled saved me heaps of time. Highly recommend if you're running a tradie setup and want something that actually lasts.(5)
Proper Kit for Remote Touring
Been running these Dobinsons struts on my Colorado for about 18 months now, including multiple Cape York trips and plenty of corrugated Simpson Desert tracks. The ride quality is noticeably better than stock, especially when loaded up with long-range fuel and camping gear. Fitment was spot-on and the lift has been consistent without any sagging, which is exactly what you need when you're 800km from the nearest mechanic.(5)
Perfect Upgrade for Our Family Camping Rig
Fitted these Dobinsons front struts to my Colorado before our last trip up to the High Country and the difference is night and day. The extra height cleared up the rake we had with the bullbar and winch, and the ride quality is actually better than stock even with a full load of camping gear. Really impressed with how well-engineered these are – proper Australian kit that handles our corrugated outback roads without any dramas.(5)
