Selecting the correct spring rate is critical for ride quality, safety and component longevity. When ordering this kit, you'll be asked to specify front and rear spring rates based on your constant accessory load — not occasional or temporary loads. Constant load includes accessories permanently fitted to your Colorado such as: steel bullbar, winch, upgraded rear bumper, steel canopy or aluminium tray, toolboxes, drawer systems, dual battery setups, long-range fuel tanks, water tanks and rooftop tents. Do not select heavier spring rates for occasional loads like camping gear, passengers or towing a trailer — this will result in an overly firm ride and potential damage to suspension components. If you're unsure about your total accessory weight, our team can help you calculate the correct spring rate for your specific build.
Professional installation by a qualified 4WD suspension specialist is strongly recommended to ensure correct fitment, torque specifications and safety compliance. While experienced DIY mechanics can install this kit using appropriate tools and workshop manuals, proper spring compressor equipment is essential for safe coil spring installation. A full four-wheel alignment is mandatory after installation to restore correct camber, caster and toe settings — failure to perform alignment will cause premature tyre wear and compromised handling. All Dobinsons kits require a 500km break-in period where springs will settle and shocks will bed-in — ride height may settle 5-10mm during this period, which is normal. For maximum suspension performance and correct geometry at 2-inch lift heights, consider pairing this kit with upgraded control arms to correct ball joint angles and improve wheel alignment range.

This kit is specifically engineered to fit all Holden Colorado RG models from 2012 onwards, including Single Cab, Space Cab and Crew Cab configurations with both the 2.8L and 2.5L turbo diesel engines. It's a direct bolt-in replacement designed to work with factory mounting points and suspension geometry. If you've already modified your Colorado with aftermarket suspension components or have a specific variant concern, our team can confirm exact compatibility. Check our fitment table above or contact us with your VIN number for 100% confirmation before ordering.
This Dobinsons kit provides approximately 50mm (2 inches) of lift at both front and rear when measured at the chassis. Actual lift height can vary slightly depending on your vehicle's current accessory load, selected spring rates, and factory tolerances — typically ranging from 45mm to 55mm once fully settled. After the initial 500km break-in period, springs will settle approximately 5-10mm, which is normal for all coil and leaf spring kits. This lift height is ideal for fitting 32-inch tyres (265/70R17 or similar) and provides noticeable improvements in ground clearance, approach and departure angles without requiring extensive modifications to other components.
This complete kit includes 2 x front nitro gas struts, 2 x front coil springs, 2 x rear nitro gas shock absorbers, 2 x rear leaf springs, 4 x U-bolts and 1 x polyurethane bush kit with all necessary leaf spring mounting hardware. Everything required for a full front and rear suspension upgrade is included except for upper control arms, extended brake lines and wheel alignment. The kit is designed as a comprehensive bolt-in solution, though depending on your specific vehicle condition and lift requirements, additional components like extended brake lines or diff drop spacers may be recommended during professional installation for optimal geometry and safety.
Absolutely — this kit is engineered specifically for heavy towing and touring loads. The rear leaf springs are designed to handle increased constant weight from tow hitches, toolboxes and cargo, while the nitrogen gas shocks provide superior damping control under load to reduce sway, bounce and shock fade when towing. When selecting your spring rates during ordering, factor in any permanently fitted towing accessories, but remember that the weight of your caravan or trailer itself is not constant load. For maximum towing stability and the ability to adjust ride height and load support, many Colorado towers add airbag suspension to the rear, which works perfectly with this Dobinsons kit.
While not strictly mandatory for a 2-inch lift, upgraded upper control arms are highly recommended to restore optimal suspension geometry, improve wheel alignment adjustment range and correct ball joint angles that change when lifting the vehicle. Factory control arms may limit your ability to achieve proper camber and caster settings after the lift, potentially causing uneven tyre wear and reduced handling performance. Many Colorado owners choose to install adjustable upper control arms at the same time as their lift kit to maximize alignment capability and ensure long-term component reliability. Our team can recommend compatible control arm options specifically matched to this Dobinsons kit during your order.
Yes, a full four-wheel alignment is absolutely mandatory after installing any lift kit. Lifting your Colorado changes suspension geometry, altering camber, caster and toe angles beyond factory specifications — driving without proper alignment will cause rapid and uneven tyre wear, poor handling, steering pull and potential safety issues. The alignment should be performed by a qualified workshop familiar with lifted 4WDs, and you should wait until after the 500km break-in period for a final check alignment once springs have fully settled. Keep your alignment printout records for future reference, and consider checking alignment again after 12 months or any significant off-road trip.
Yes, and this is actually essential for optimal performance — you must select appropriate spring rates for both front and rear based on your specific constant accessory loads. During the ordering process, you'll specify front spring rate (based on bullbar, winch, upgraded bumper weight) and rear spring rate (based on canopy/tray, toolboxes, drawer systems, dual batteries, etc.). Dobinsons offers multiple spring rate options to match different load configurations, ensuring you get the right balance of load support and ride comfort. Selecting too heavy a spring rate for your actual load will result in a harsh, uncomfortable ride, while too light a rate will cause excessive sag and bottoming out.
This 2-inch lift typically allows fitment of tyres up to 32 inches in diameter (such as 265/70R17 or 265/65R18) with minimal to no rubbing on factory wheels and standard offset. Clearance depends on wheel offset, backspacing and specific tyre width — wider tyres or aggressive tread patterns may require minor trimming of plastic inner guards or mudflaps, especially at full lock and compression. For 33-inch tyres and larger, additional modifications such as guard trimming, diff drop or body lift may be required. We recommend test-fitting tyres at full lock and compression before committing to a tyre purchase, and considering a wheel alignment specialist's advice on optimal wheel offset for your chosen tyre size.
Dobinsons stands behind their products with comprehensive manufacturer warranty coverage on all components in this kit. Shock absorbers and struts typically carry a limited lifetime warranty against manufacturing defects, while springs are covered by a substantial multi-year warranty period (specific terms available on request). Warranty coverage requires professional installation with proof of purchase, proper vehicle usage within load ratings, and regular maintenance including inspection of mounting hardware and bushings. As an authorized Dobinsons dealer, we provide full warranty support and can assist with any claims or technical issues that may arise during the warranty period.
Absolutely — one of Dobinsons' key design goals is delivering genuine off-road capability without compromising on-road comfort and daily drivability. The Nitro Gas twin-tube technology with vehicle-specific valving provides a comfortable, controlled ride on highways and city streets while still offering the performance needed for off-road touring and heavy loads. Unlike budget lift kits that can feel harsh or vague on-road, Dobinsons' engineering ensures reduced noise, vibration and harshness (NVH) through quality bushings and precision valving. Thousands of Colorado owners use Dobinsons-equipped vehicles as daily drivers, work trucks and family tourers, appreciating the blend of comfort, capability and long-term reliability across all driving conditions.
