Selecting the correct spring rate is critical for ride quality, handling and component longevity. Base your selection only on constant accessory weight — the total weight of permanently installed equipment on your vehicle, not occasional loads like camping gear or towing. Common front accessories include bull bars (30-50kg), winches (35-60kg), driving lights, UHF aerials and roof racks with Maxxtrax or jerry cans. Rear constant loads include canopies or hard lids (50-80kg), drawer systems (60-120kg), dual battery setups, long-range fuel tanks (40-70kg empty), rear bars and permanent toolboxes. If you frequently carry variable loads or tow heavy trailers, consider pairing your lift kit with airbag suspension for on-demand adjustability without compromising unladen ride comfort.
Professional installation by a qualified suspension specialist or experienced 4WD mechanic is strongly recommended for this comprehensive lift kit. Wheel alignment is mandatory following installation to ensure correct steering geometry, even tyre wear and safe handling characteristics. Allow a 500km break-in period for springs to settle and shocks to bed in before final ride height measurement and alignment adjustments. Colorado RG models lifted beyond 40mm may benefit from upgraded control arms to restore optimal castor angle and improve steering feel, particularly when fitting larger tyres. Extended brake lines may also be required depending on total suspension travel increase — consult your installer or our technical team for vehicle-specific recommendations.
Toughdog has earned its reputation as Australia's number one 4WD suspension brand through decades of proven performance in the harshest touring and work conditions across the country. Every kit is engineered and validated in Australia using real-world testing protocols including Cape York, the Simpson Desert and Canning Stock Route — not just lab simulations. Trusted by everyone from grey nomad tourers and adventure families to mining contractors and rural tradespeople, Toughdog delivers the rare combination of genuine off-road capability and comfortable daily drivability. Explore the complete Toughdog suspension range for complementary upgrades including steering dampers, extended shackles and performance accessories.
This comprehensive Toughdog lift kit is ideal for Holden Colorado RG owners who demand more from their vehicle: outback tourers needing clearance for remote tracks and river crossings, caravan towers requiring stable load-carrying capacity, tradespeople with constant heavy payloads in the tray, and adventure families fitting roof tents, dual batteries and long-range tanks. If your Colorado regularly carries maximum GVM loads or you tow close to rated capacity, consider upgrading to the heavy-duty 300kg or 500kg rear leaf spring option, or add airbag suspension for ultimate load management flexibility. Whether you're building a capable tourer or upgrading your work rig, this kit delivers the foundation for years of reliable service.

This kit is specifically engineered for Holden Colorado RG series from 2012 onwards, including all variants: single cab, space cab, crew cab, 2WD, 4WD and the Colorado 7 wagon (2012-2016). It suits both 2.5L and 2.8L turbo diesel engines. To confirm exact fitment for your specific build date or if you've made previous modifications, check your VIN against our parts finder or contact our technical team who can verify compatibility within minutes.
This Toughdog suspension kit delivers approximately 40-50mm of lift at both front and rear, depending on your selected spring rates and constant accessory load. The lift provides clearance for 31-32 inch tyres (265/70R17 or 265/65R18) without rubbing under most conditions. Final ride height will settle after the initial 500km break-in period and will vary based on your specific payload configuration. Vehicles with heavy constant loads may experience slightly less lift than unladen measurements suggest.
This comprehensive kit includes front strut assemblies, front raised coil springs (your choice of load rating), rear leaf spring assemblies, rear shock absorbers, rear spring U-bolt kit and rear spring bush kit — everything needed for a complete front and rear suspension replacement. You'll need to select your preferred front spring rate (0-60kg or 60-100kg constant) and can optionally upgrade rear leaf springs to 300kg or 500kg constant load rating. Upper control arms, extended brake lines and differential drop brackets are not included but may be recommended depending on your specific setup.
Absolutely — this kit is engineered to handle the demands of regular towing with significantly improved performance over factory suspension. The upgraded leaf springs and matched shock valving reduce rear squat, maintain level ride height under towball weight, and improve braking stability when towing caravans, camper trailers or boat trailers. For maximum towing capability, we recommend selecting the heavy-duty 300kg or 500kg constant load rear leaf springs. If you tow occasionally rather than constantly, consider adding airbag suspension for on-demand load support without compromising unladen ride comfort.
While not mandatory for the 40-50mm lift provided by this kit, upgraded upper control arms are highly recommended to restore optimal castor and camber angles, particularly if you're also fitting larger tyres. Aftermarket control arms correct steering geometry, improve on-centre feel, reduce tyre scrub and allow proper wheel alignment to manufacturer specifications. The benefits become more noticeable during highway driving, when cornering under load, and during extended touring. Our suspension specialists can advise on whether your specific build and intended use would benefit from this upgrade.
Yes, professional four-wheel alignment is absolutely mandatory after installing any lift kit. The suspension geometry changes significantly when ride height increases, affecting camber, castor and toe settings across all wheels. Without proper alignment, you'll experience uneven and accelerated tyre wear, poor steering feel, vehicle pull to one side, and potentially compromised handling safety. Always have alignment performed by a qualified suspension specialist using laser alignment equipment, and recheck alignment after the initial 500km break-in period once springs have fully settled.
Select spring rates based only on your constant accessory weight — the combined weight of permanently installed equipment, not occasional loads like camping gear or towing. Measure or estimate your front accessories (bull bar, winch, driving lights, long-range tank if front-mounted) and rear accessories (canopy, drawer system, dual batteries, rear bar, permanently mounted toolboxes). Front springs are available in 0-60kg or 60-100kg constant load ratings; rear springs come standard or can be upgraded to 300kg or 500kg constant. Selecting springs that are too heavy for your actual load will result in harsh ride quality and potential component damage. When in doubt, contact our team for personalised spring rate recommendations.
With the 40-50mm lift provided by this kit, you can typically fit 265/70R17 or 265/65R18 tyres (approximately 31-32 inches) without body modifications on standard offset wheels. Tyre clearance depends on several factors including wheel offset, tyre brand and tread pattern, suspension articulation, and whether you've installed wider track components. Some light trimming of plastic inner guards may be required for full articulation clearance, particularly if running aggressive tread patterns. For larger tyres or extreme offsets, additional modifications such as body lifts, guard trimming or aftermarket flares may be necessary.
This Toughdog suspension kit is backed by the manufacturer's comprehensive Australian warranty program covering defects in materials and workmanship. Warranty terms vary by component type (typically 12-24 months depending on the part) and require professional installation with proof of purchase. Toughdog's Australian head office and nationwide dealer network provide local warranty support and assessment. Warranty does not cover wear items, damage from incorrect installation, overloading beyond rated capacity, or modifications. Always retain your purchase receipt and installation records for warranty claims.
Yes, Toughdog suspension is specifically engineered to deliver excellent on-road manners for daily driving, commuting and highway touring while dramatically improving off-road capability. The carefully tuned shock valving and progressive spring rates maintain composed handling, reduced body roll and comfortable ride quality on sealed roads. Many Colorado owners report improved steering feel and reduced body movement compared to worn factory suspension. The kit excels in mixed-use scenarios — comfortable enough for the daily school run and grocery shopping, yet capable enough for weekend adventures and serious remote touring.
Proper Kit for Serious Remote Touring
Been running this Toughdog lift kit on my RG Colorado through the Canning Stock Route and Simpson Desert, and it's handled the punishment without any dramas. The customisable spring rates meant I could spec it for my heavy touring setup with dual batteries, long-range tank and rooftop tent. Ride quality loaded up is miles better than the factory setup ever was, and the hardware quality gives me confidence when I'm days from civilisation.(5)
Perfect upgrade for our family camping rig
Had this Toughdog lift kit fitted to our 2015 Colorado a few months back and it's been brilliant for our regular trips down to the South Coast and out Snowy Mountains way. The ride quality with the kids and all our camping gear loaded up is actually better than stock, which really surprised me. Installation was straightforward according to my mechanic, and the kit came with everything needed including all the bolts and bushings.(5)
Perfect Setup for Serious Remote Touring
Been running this Toughdog lift kit on my RG Colorado for the past 18 months through some pretty punishing Cape York and Simpson Desert trips. The ride quality loaded up with gear and water is noticeably better than the old setup, and the adjustable spring rates meant I could dial it in perfectly for my camper and long-range fuel setup. Fitment was spot-on with all the hardware included, saved me a return trip to the auto shop. Worth every cent for anyone doing genuine remote work.(5)
Perfect Upgrade for Our Family Camping Rig
Fitted this Toughdog lift kit to our 2015 Colorado a few months back and it's been brilliant for our regular trips down to the High Country and along the coast. The ride quality is noticeably better than stock, especially when we've got the camper trailer hooked up and the kids' gear loaded in the back. Installation was straightforward enough for our local mechanic, and the difference in clearance has already paid off on some rougher tracks we wouldn't have attempted before.(5)
Perfect for the Tradie's Daily and Weekends
Fitted this Toughdog lift kit to my RG Colorado about six months back and it's been absolutely brilliant for carting tools and materials around job sites during the week, plus it handles the bush tracks on the weekend like a dream. The ride quality is heaps better than stock even when loaded up, and the spring rates they recommended for my setup were spot on. Well worth the money and haven't had a single issue with any of the components.(5)
