Choosing the right spring rate depends on what you carry day to day, not just occasionally. The King coil springs in this kit are matched to the standard wagon weight plus a moderate accessory load — think bull bar, winch and roof rack up front, and drawers, fridge or camping gear out back. If your constant load is heavier again, such as long-range fuel tanks or dual batteries, contact our team before ordering to confirm the coil rate suits your setup or to discuss alternative coil springs.
Fitment requires suspension experience or a qualified workshop — this is a bolt-in shock and spring swap, but working at height with coil springs needs proper spring compressors and correct safety procedure. Wheel alignment is mandatory after fitting to bring castor, camber and toe back within factory tolerance at the new ride height. Allow a 500km settling period for the King coil springs to bed in before locking in your final alignment figures. For correct geometry at 2" of lift, pair this kit with control arm upgrades to reduce CV joint wear.
Bilstein has built monotube shock absorbers for decades and supplies original equipment suspension to vehicle manufacturers globally, not just the aftermarket. The B6 Offroad range in this kit uses the same monotube gas-pressure technology found across Bilstein's touring line-up, backed by a manufacturer warranty through 4WD Suspension. Australian tourers and tradespeople run Bilstein on the Colorado7 and Trailblazer for the balance of daily comfort and load-carrying ability — view the full Bilstein range for other applications.
This kit suits Colorado7 and Trailblazer owners fitting a bull bar and winch, running a rooftop tent, or towing a box trailer or small caravan regularly. It also suits tradespeople carrying tools and equipment who want more clearance without losing on-road manners for the daily commute. If you're carrying a constant heavy load such as a loaded canopy, ask about airbag suspension to supplement the rear coils for load levelling.

Yes, this Bilstein 2" lift kit is built for the Holden Colorado7 and Trailblazer wagon (RG series) from 2012 onwards, fitted with the 2.8L Duramax diesel engine. It bolts in place of the factory shocks and coil springs at each corner without cutting or welding. If you're unsure of your exact build date or series, check with our fitment team via the contact page before ordering. Confirming these details avoids ordering the wrong kit for your vehicle.
This kit provides a 2" lift front and rear, achieved through Bilstein B6 Offroad shocks matched to King coil springs raised 2" over standard ride height. The lift comes from spring height rather than spacers, so it holds up over time under normal accessory loads. Actual ride height can vary slightly depending on vehicle condition and accessory weight already fitted. Our team can confirm expected clearance for your specific setup.
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 two Bilstein B6 Offroad monotube front shocks, two rear shocks, two front King coil springs and two rear King coil springs, plus mounting hardware and bushes. Fitting instructions are included with the kit. Upper control arms and steering dampers are not included and are available separately if you need them. See the full kit contents list above for exact quantities.
Yes, this kit is a common choice for Colorado7 and Trailblazer owners towing a box trailer or small caravan. The B6 Offroad monotube shocks help control body movement under tow ball load, and the King coil springs support the added static weight of towing accessories. For heavier constant tow ball loads, ask our team about a firmer rear spring rate or supplementary airbag suspension. Match your spring selection to your actual loaded weight, not just the empty vehicle.
Not always, but at 2" of lift the factory control arms will sit at a slightly different angle, which can affect CV joint life over time. Upgrading to control arms designed for lifted vehicles corrects this geometry and reduces uneven wear. It's a common pairing with this lift kit rather than a mandatory requirement. Our team can advise based on how you use the vehicle and your typical driving conditions.
Yes, wheel alignment is mandatory after installing this lift kit. Ride height changes affect castor, camber and toe, and running the vehicle without realignment leads to uneven tyre wear and can affect handling. We recommend allowing the King coil springs to settle over roughly 500km before locking in the final alignment figures. Book alignment with a workshop experienced in lifted 4WDs for best results.
This kit ships with King coil springs suited to a standard wagon plus a moderate accessory load such as a bull bar and touring gear. If your constant load is heavier, such as long-range fuel tanks or a loaded canopy, contact our team before ordering. We can advise on a firmer coil rate or discuss alternative coil springs to suit your setup. Matching spring rate to actual load keeps ride height correct and protects handling.
A 2" lift typically creates extra clearance for a modest increase in tyre diameter over standard, depending on your current wheel offset and guard profile. Some vehicles may need minor guard trimming or flares to run larger tyres without rubbing at full lock or full compression. We recommend confirming your intended tyre size with our team before purchase. This helps avoid clearance issues after fitment.
This kit is backed by Bilstein's manufacturer warranty on the B6 Offroad shock absorbers, supplied and supported through 4WD Suspension in Australia. Warranty covers manufacturing defects under normal use and correct installation. Keep your proof of purchase and have the kit fitted and aligned correctly to maintain warranty cover. Contact our team if you have any warranty questions after installation.
Yes, this kit is designed to work as a daily driver setup, not just for off-road use. The Bilstein B6 Offroad monotube shocks are tuned to control body movement without a harsh ride on sealed roads. Many Colorado7 and Trailblazer owners run this kit for the school run and commute as well as weekend touring. Correct spring rate selection for your accessory load helps keep the daily ride comfortable.
