The Bilstein 2" Lift Kit for the Holden Colorado RC (2006-2012) pairs German-engineered B6 Offroad monotube shocks with heavy-duty rear leaf springs and re-indexed front torsion bars to lift the vehicle evenly front and rear. Monotube construction keeps oil and gas separated for consistent damping over corrugations and under constant load, while the upgraded leaf pack and HD shackle bushes support touring gear without sagging. This complete 4WD lift kit ships from Australian stock with a manufacturer warranty and fitment support from our team.

Choose your rear leaf spring rate based on what you carry day to day, not just what you carry occasionally. A steel tray, canopy, dual battery setup or full-size spare on a rear carrier all add constant load that a standard-rate leaf can't support long term. If you run a caravan or camper trailer with heavy ball weight, tell our team so we can confirm the leaf rate before dispatch — mismatched rates lead to rear sag or a harsh empty-vehicle ride.
This kit is best fitted by an experienced 4WD workshop, particularly for the torsion bar re-indexing step which requires the correct spanner and torque sequence. Wheel alignment is mandatory once the kit is installed, since castor and toe change with ride height. Allow a 500km break-in period for the new shocks and leaf springs to settle before final alignment. Many customers pair this kit with upgraded control arms to correct front geometry and restore factory-plus CV joint angles at the new ride height.
Bilstein has built monotube shock absorbers for German OEM and aftermarket applications for decades, and the B6 Offroad range is tuned specifically for lifted 4WDs carrying extra weight. Each shock is backed by a manufacturer warranty and is a common fitment choice among tradespeople and grey-nomad tourers running the Colorado RC. You can view the full Bilstein range to compare this kit against other lift heights and shock series.
This kit suits Colorado RC owners who tow, carry canopy or tray weight for work, or fit larger touring tyres and need the ground clearance to match. If your rear load varies significantly trip to trip, it's worth comparing this leaf-spring setup against airbag suspension for adjustable load support. Tradespeople running steel trays and tourers fitting rooftop tents both commonly specify this combination.

Yes, this Bilstein kit is built specifically for the Holden Colorado RC sold in Australia from 2006 to 2012, covering both the 3.0L Duramax turbo-diesel and 3.6L V6 petrol variants. It suits single-cab, space-cab and dual-cab body styles fitted with the standard RC leaf-spring rear end and torsion bar front end. If you're unsure of your build date or variant, our team can confirm fitment before you order. You can also check compatible parts using our Colorado RC parts finder.
This kit delivers a 2" lift front and rear once settled at kerb weight. Front lift comes from re-indexing the factory torsion bars to a higher setting, matched to the firmer B6 Offroad shock valving. Rear lift comes from the heavy-duty leaf spring pack included in the kit. Final ride height can vary slightly depending on accessory load, so we recommend confirming your typical loaded weight when ordering.
Please note that all assembled struts are dispatched at a height based on our experience and the manufacturer’s specifications for the advertised lift. Coil springs and leaf springs are also manufactured according to the advertised height and constant-load rating. Actual vehicle height may vary depending on the vehicle and the weight of fitted accessories. Further adjustment may therefore be required after installation. The installer may use coil spacers or adjust the struts at their discretion to achieve the desired height. We are not responsible for vehicle-specific height variations or any additional adjustments required after installation.
The kit includes 2 x Bilstein B6 Offroad front shocks, 2 x Bilstein B6 Offroad rear shocks, a heavy-duty rear leaf spring pair, HD shackle bushes, U-bolts sized for the raised leaf pack, and the hardware needed for front torsion bar re-indexing. Upper control arms and steering dampers are not included and are sold separately. Full fitting instructions are supplied with the kit.
Yes, the heavy-duty rear leaf springs in this kit are chosen to support constant accessory and towing loads better than the factory leaf pack. If you regularly tow near your Colorado's maximum ball weight, tell our team your typical loaded weight so we can confirm the correct leaf rate for your use. For highly variable loads, our airbag suspension range is worth comparing as an alternative or add-on.
It's not mandatory, but it's recommended once you're running a 2" front lift. Upgraded control arms correct the geometry changes that come with extra ride height, restoring proper CV joint angles and camber/castor range for alignment. Running the standard arms at 2" is possible but reduces the amount of adjustment available at alignment time. Ask our team if you're also planning larger tyres, as this affects the recommendation.
Yes, wheel alignment is mandatory after installing this kit. Ride height changes alter castor, camber and toe, and running the vehicle without a post-fit alignment accelerates tyre wear. We recommend allowing a 500km break-in period for the new shocks and leaf springs to settle before the final alignment is done.
The rear leaf spring rate in this kit is matched to typical Colorado RC accessory and touring loads. If you run a heavier steel tray, canopy or regularly tow near maximum ball weight, contact our team before ordering so we can confirm whether a firmer leaf pack suits your setup better. Getting the rate right up front avoids rear sag or an overly stiff unladen ride.
A 2" lift on the Colorado RC typically creates clearance for a modest increase in tyre diameter over standard, though exact clearance depends on wheel offset and any flares fitted. We recommend checking your specific tyre size with our team before purchase, especially if you're also running a wider wheel. Pairing this kit with the recommended control arm upgrade also helps maintain clearance through full steering lock and suspension travel.
Bilstein shocks in this kit are covered by the manufacturer's warranty against manufacturing defects. Leaf springs and hardware are covered under standard supplier warranty terms. Keep your proof of purchase and have the kit fitted and aligned correctly, as incorrect installation can affect warranty claims. Contact our team if you have any questions about warranty terms before or after purchase.
Yes, the Bilstein B6 Offroad shock's digressive valving is tuned to control small bump input on sealed roads while still firming up for larger off-road inputs, so the ride stays composed for daily commuting. The rear leaf rate is matched to typical accessory loads rather than an extreme off-road-only rate. Most Colorado RC owners run this kit as their everyday setup, using it for both work and weekend touring.
