The Dobinsons Monotube IFP 2" Lift Kit is purpose-built for the Holden Colorado 7 RG and Trailblazer wagon, pairing monotube shocks with an Internal Floating Piston for consistent damping under heat and load. This kit lifts the vehicle a genuine 2" front and rear using vehicle-specific coil springs, opening up clearance for larger touring tyres. The monotube design separates oil and gas with the IFP, reducing fade on corrugations and long descents compared to twin-tube units. Dispatched from Australian stock with Dobinsons' manufacturer warranty and fitment guidance from our suspension team.

Choose your spring rate based on what you carry day to day, not just occasional trips. Constant loads such as a bullbar, winch, rear drawers, long-range fuel tank or a caravan tow ball weight all push a standard-rate spring closer to its limit, causing rear sag. If you regularly carry these accessories, talk to our team about a firmer rear coil to keep the vehicle sitting level and the 2" lift height consistent.
This kit is best fitted by an experienced 4WD suspension installer or a competent DIY mechanic with a coil spring compressor and vehicle hoist. Wheel alignment is mandatory after fitment to bring camber, caster and toe back within factory specification at the new ride height. Allow a 500km bed-in period for the springs and shock seals to settle before final alignment if your installer recommends a two-stage check. For vehicles running larger tyres or a heavier front bar, pairing this kit with upgraded control arms corrects geometry and CV angles at the new height.
Dobinsons has supplied 4WD suspension into the Australian market for decades, with components developed and tested locally against local road and track conditions. Every Monotube IFP shock is backed by a manufacturer warranty, and our team stocks genuine Dobinsons parts for fast dispatch rather than special order. Tourers and tradespeople across Australia run Dobinsons kits because the componentry is designed around real accessory loads, not just showroom ride height — view the full Dobinsons range for other Colorado 7 and Trailblazer options.
This kit suits Colorado 7 and Trailblazer owners fitting larger touring tyres, running a bullbar and winch, or wanting sharper handling over corrugations without a harsh daily ride. Tradespeople carrying tools and gear in the rear will benefit from the raised rear coil under constant load, and families towing a camper or small caravan get more predictable body control. If your rear load varies significantly trip to trip, also look at our airbag suspension options to fine-tune ride height under variable loads.
This Dobinsons Monotube IFP 2" Lift Kit is in stock in Australia and ready for fast dispatch, with our suspension team on hand to confirm fitment for your specific Colorado 7 or Trailblazer build.

Yes, this Dobinsons Monotube IFP kit is built specifically for the Holden Colorado 7 RG (2012-2016) and Trailblazer RG (2016-2020) 7-seat wagon. It is not a shared kit with the Colorado ute, since the RG7 wagon runs a different rear coil spring suspension setup. If you're unsure of your build date or series, our team can confirm fitment from your VIN or compliance plate before you order.
This kit provides a 2" lift front and rear using Dobinsons' vehicle-specific raised coil springs. The lift is achieved through spring design rather than spacers, so the shock's usable travel is preserved. Actual ride height can vary slightly depending on your vehicle's existing load and accessory fitment.
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 front and 2 rear Dobinsons Monotube IFP shock absorbers, plus 2 front and 2 rear raised coil springs matched to the RG7 chassis. Mounting bushes and hardware for the shocks are included, along with fitment instructions. Upper control arms and steering components are sold separately if your setup requires them.
Yes, the monotube IFP shock design is intended to maintain consistent damping under sustained load, which suits towing a caravan or trailer. If you tow regularly with significant tow ball weight, ask our team about a firmer rear coil spring option to prevent rear sag. Matching the spring rate to your actual constant load keeps the 2" lift height consistent while towing.
A control arm upgrade is not mandatory with this 2" lift but is worth considering if you're also running larger tyres or a heavier front bar. Upgraded control arms help correct CV joint and camber angles at the new ride height. Our control arm range covers RG7-compatible options if you decide to add them.
Yes, wheel alignment is mandatory after installing this kit. Ride height changes affect camber, caster and toe, and correct alignment protects tyre wear and steering feel. We recommend a check after the initial fitment and again after the 500km bed-in period.
Dobinsons offers rear coil spring options rated for different constant accessory loads, so you can match the spring to what you actually carry — drawers, canopy, dual battery setup or tow ball weight. Selecting the correct rate keeps the vehicle sitting level rather than sagging under a heavier rear load. Speak with our fitment team about your typical load before ordering if you're unsure which rate suits you.
The 2" lift is designed to open up clearance for larger touring tyres than what fits under a standard-height Colorado 7 or Trailblazer. Exact tyre size clearance depends on your wheel offset and whether you've fitted flares or a body lift. Our team can advise on a suitable tyre and wheel combination for your specific setup.
This kit is covered by Dobinsons' manufacturer warranty on both the Monotube IFP shocks and the coil springs. As an authorised Dobinsons stockist, we handle warranty support directly for Australian customers. Contact our team with your order details if you ever need to make a claim.
Yes, the Monotube IFP shock and matched coil spring combination is tuned to balance daily on-road comfort with the extra control needed for gravel roads and light touring tracks. Many owners run this kit as their only suspension setup for commuting, towing and weekend touring. If your driving is mostly around town with a heavy commercial payload, our team can also discuss airbag suspension as a complementary option.
