Rear leaf spring rate should be matched to what sits on the tray or tub most of the time — a bare tray back has very different needs to one carrying a canopy, tool boxes and a fridge slide. Common accessories that shift the rear load include steel bull bars, winches, long-range fuel tanks, canopies, drawer systems and caravan or trailer tow ball weight. If your accessory load changes often, our team can help you weigh up a fixed leaf pack against adding airbag suspension for adjustable support.
This is a full front and rear suspension change and we recommend an experienced 4WD workshop or a confident DIY installer with the right tools and a hoist. Wheel alignment is mandatory after fitting to bring camber, caster and toe back within specification at the new ride height. Allow a 500km settling-in period for the new springs and shocks before final alignment if your installer prefers to check it post bed-in. Many owners fit upgraded control arms at the same time to correct front geometry and CV angles at 2" of lift.
Bilstein has built monotube shock absorbers for decades and the B6 range is tuned specifically for lifted 4WDs rather than adapted from a standard-height application. Kits are backed by a manufacturer warranty and stocked here in Australia, so replacement parts and fitment advice are a phone call away, not an overseas order. Tradespeople and tourers running Colorado RG utes choose Bilstein for the combination of load-carrying leaf springs and a shock tune that stays composed both loaded and empty — view the full Bilstein range for other RG-compatible options.
This kit suits Colorado RG owners who tow regularly, carry a canopy or tray load, or want extra clearance for touring tracks without moving to a 3" kit. Tradespeople with constant tool and equipment weight benefit from the heavy-duty leaf springs, while grey nomads towing a van get more controlled rear squat under tow ball load. If your load varies week to week, ask us about airbag suspension as a rear-end add-on instead of, or alongside, the leaf pack.

Yes, this Bilstein kit is designed for the Holden Colorado RG built between 2012 and 2020, covering both the pre-facelift 2.5L/2.8L models and the 2016-on 2.8L Duramax facelift. It suits both Space Cab and Crew Cab 4x4 variants. If you're unsure of your exact build date or engine, check your compliance plate or use our Colorado RG parts finder before ordering. Our team can confirm fitment against your VIN if needed.
This kit delivers a 2" lift at both the front and rear of the Colorado RG. The front lift comes from King Springs raised coil springs paired with Bilstein B6 shocks, and the rear from heavy-duty leaf springs of the same lift height. This keeps the vehicle sitting level front to rear rather than nose-high or tail-high. It's a moderate, on-road-friendly lift compared to a 3" kit.
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 monotube front shocks, two Bilstein B6 monotube rear shocks, King Springs raised front coil springs, and King Springs heavy-duty rear leaf spring packs. U-bolts, shackle bushes, bump stop spacers and mounting hardware are included where required. Upper control arms are not included and are sold separately if your setup needs them.
Yes, the heavy-duty rear leaf springs are specifically chosen to support constant accessory and tow ball load better than the factory leaf pack. The Bilstein B6 monotube shocks control rear body movement under load, which helps keep the tow setup composed on corrugated or uneven roads. If your tow ball weight varies a lot, ask us about airbag suspension as a complementary option rather than relying on leaf springs alone.
It depends on how you use the vehicle and how much additional geometry correction you want at 2" of lift. Many Colorado RG owners run this kit without changing control arms and get correct alignment within factory adjustment range. Others fitting a 2" lift alongside larger tyres or heavier front accessories choose to add upgraded control arms for improved CV angles and camber range. Our team can advise based on your specific accessory list.
Yes, wheel alignment is mandatory after installing this kit. The 2" lift changes camber, caster and toe from factory settings, and running the vehicle without realignment accelerates uneven tyre wear. We recommend aligning the vehicle once the suspension has settled, generally after a short bed-in drive. Your installer should check alignment again after the first 500km if it wasn't set at final ride height initially.
The rear leaf springs in this kit are heavy-duty rated for constant accessory loads such as canopies, drawers and tow ball weight. If your load is lighter or heavier than average, talk to our team before ordering, as we can advise on alternative King Springs rates suited to your specific accessory setup. Getting the rate right up front avoids a sagging or overly firm rear end once everything is loaded.
A 2" lift on the Colorado RG typically provides enough extra clearance for a modest tyre size increase over standard, though exact clearance depends on wheel offset and width. We recommend confirming your specific tyre and wheel combination with our team before purchase, as guards and flares may need trimming for larger sizes. This kit alone doesn't guarantee clearance for very large tyre upgrades without additional bodywork.
This kit is covered by Bilstein's manufacturer warranty on the shock absorbers, alongside standard warranty terms on the King Springs coil and leaf springs. Exact warranty periods and terms are confirmed at the time of purchase and vary by component. Keep your proof of purchase and have the kit fitted by a qualified installer to ensure warranty claims are straightforward. Contact our team if you need the specific warranty documentation for your order.
Yes, the Bilstein B6 monotube shock tune is set up to balance daily on-road comfort with the load-carrying and off-road benefits of the kit. Owners drive the Colorado RG on this setup as a daily and weekend vehicle without a harsh or unsettled ride when unladen. The heavy-duty rear springs may feel firmer than factory when the tray is empty, which is normal for a load-rated leaf pack. It settles once carrying its intended accessory or tow load.
