Selecting the correct spring rate is critical for optimal performance and ride quality. Choose your spring rate based on your constant accessory load—the weight permanently fitted to your Colorado 7. Front constant loads include bull bars, winches, steel replacement bumpers, driving lights, and upgraded battery systems. Rear constant loads include steel canopies, drawer systems, dual spare wheel carriers, long-range fuel tanks, water tanks, and permanently installed camping equipment. Do not factor occasional loads such as passengers, camping gear loaded for trips, or trailer towing—selecting overly heavy springs based on occasional use will result in harsh ride quality and potential damage to other suspension components. When in doubt, our suspension specialists can calculate your exact load requirements.
Professional installation by a qualified mechanic or experienced 4WD workshop is strongly recommended for this complete suspension system. The installation involves removal of factory struts, springs, and shocks, requiring specialized spring compressor tools and appropriate lifting equipment. Wheel alignment is mandatory after installation to ensure proper 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 is achieved. For Colorado 7 models with significant front-end weight from bull bars and winches, consider pairing this kit with upgraded control arms to correct caster angle and restore factory steering feel.

This Toughdog suspension kit is specifically engineered for the Holden Colorado 7 (RG Series) manufactured between 2012 and 2016, covering all LT and LTZ variants. The kit is designed to work with the factory coil spring front and rear setup unique to the Colorado 7 SUV platform. If you have modified your vehicle with aftermarket suspension components or have an imported variant, we recommend contacting our team to confirm compatibility. Our fitment specialists can verify your VIN and current suspension setup to ensure perfect compatibility before you order.
This complete Toughdog kit delivers approximately 40-50mm of lift at both front and rear axles, measured from factory ride height. The actual lift achieved depends on your constant accessory load, spring rate selection, and current vehicle condition—older vehicles with sagging factory springs may see greater lift measurements. After the initial 500km break-in period, springs will settle by approximately 10-15mm as they bed in. This lift height provides noticeable improvement in ground clearance and approach/departure angles while maintaining safe steering geometry and handling characteristics without requiring additional modifications.
This complete kit includes two front strut assemblies, two front raised coil springs, two rear raised coil springs, two rear shock absorbers, plus all necessary mounting hardware and bushings required for installation. The front struts are complete units ready to install, eliminating the need for spring compression during fitment. You can select custom spring rates for both front and rear based on your constant accessory load when ordering. Note that extended brake lines, upper control arms, diff drop kits, and alignment services are not included and may be required depending on your specific vehicle configuration and lift requirements.
Yes, this Toughdog kit is excellent for towing applications when properly configured with appropriate rear spring rates. The upgraded rear coil springs and heavy-duty shock absorbers significantly reduce squat under tow ball loads, maintaining proper suspension geometry and headlight aim when towing caravans or trailers. Select medium or heavy-duty rear spring rates if you regularly tow at or near your Colorado 7's rated towing capacity. For the ultimate towing setup, many customers pair this lift kit with supplementary airbag suspension for fine-tuned load adjustment and maximum stability. The improved suspension control also enhances braking performance and reduces trailer sway during highway towing.
Upgraded control arms are not mandatory for this 40-50mm lift on the Colorado 7, but they are highly recommended if you have significant front-end weight from bull bars, winches, or steel bumpers. The modest lift height generally maintains acceptable caster and camber angles within factory tolerance. However, aftermarket control arms with caster correction can restore optimal steering feel, reduce tyre scrub, and improve handling precision—particularly noticeable during highway driving and corrugated road conditions. If you experience vague steering or accelerated inner tyre wear after installation, control arm upgrade should be your first consideration.
Yes, professional four-wheel alignment is absolutely mandatory after installing this suspension kit. Lifting your Colorado 7 alters suspension geometry including camber, caster, and toe angles—all critical for safe handling, predictable steering response, and even tyre wear. Even though the lift is modest, the change in ride height affects these alignment parameters enough to require professional adjustment. Most reputable suspension workshops include alignment in their installation quote. Skipping alignment will result in premature tyre wear, wandering steering, and potentially dangerous handling characteristics, particularly during emergency braking or evasive maneuvers.
Absolutely—selecting the correct spring rate for your specific load requirements is one of the most important decisions when ordering this kit. Calculate your constant front load (bull bar, winch, driving lights) and constant rear load (canopy, drawers, dual batteries, water tanks) separately, then select appropriate spring rates for each axle independently. Front and rear loads are rarely identical, so different spring rates are common and recommended. Our team can help you calculate exact load weights and recommend ideal spring rates. Remember to base selection only on permanently fitted accessories—not occasional loads like camping gear or passengers—to avoid overly stiff ride quality.
The 40-50mm lift provided by this kit will improve clearance for slightly larger tyres compared to factory specifications, but fitment depends on your current tyre size and wheel offset. Most Colorado 7 owners can fit up to 265/65R17 or 265/70R17 tyres without rubbing under normal driving conditions, though extreme articulation off-road may cause minor contact with inner guards. Fitting significantly larger tyres may require additional modifications such as guard trimming, wheel spacers, or aftermarket offset wheels. Always test fit and perform full lock turning and suspension compression checks before committing to new tyres. Larger tyres also affect speedometer accuracy and may require recalibration.
Toughdog stands behind their products with comprehensive manufacturer warranty coverage on all components in this kit, reflecting their confidence in design and durability. Specific warranty terms vary by component type—shocks and struts typically carry warranty against manufacturing defects, while springs are covered for breakage or sagging beyond specified tolerances. Warranty coverage requires professional installation with proof of purchase and compliance with break-in procedures. The warranty does not cover damage from improper installation, vehicle accidents, competition use, or modification of components. Keep your installation receipt and register your purchase with Toughdog to ensure full warranty protection throughout the coverage period.
Yes, this Toughdog kit is engineered specifically to maintain comfortable daily driving characteristics while delivering enhanced off-road capability and load-carrying performance. The foam cell shock technology and carefully calibrated spring rates provide progressive damping that soaks up urban bumps and highway undulations with minimal harshness. Unlike aggressive competition-oriented suspension, this kit prioritizes on-road comfort for the 90% of driving most Colorado 7 owners do on sealed roads, while still delivering controlled performance when you venture off the bitumen. Thousands of Australian families tour and commute daily on Toughdog suspension, proving its real-world versatility for everything from school runs to remote desert crossings.
Proven Kit Through Cape York and Beyond
Been running this Toughdog lift kit on my Colorado 7 for over 18 months now, covering everything from the Gibb River Road to corrugated desert tracks out near Birdsville. The ride quality is genuinely impressive—firm enough for a loaded roof and drawer system but still comfortable on long highway stretches between remote tracks. Fitment was spot-on and the raised coils have handled some serious punishment without any sagging or issues.(5)
Perfect Upgrade for Family Camping Adventures
Fitted this Toughdog lift kit to our Colorado 7 before our trip down the Murray and what a difference it's made. The ride quality is noticeably better even when loaded up with camping gear and the kids in the back, and it handles the corrugated tracks so much smoother than the factory suspension. Really impressed with how well engineered it is for our conditions – you can tell it's built to handle Aussie roads. Couldn't be happier with the investment.(5)
Proper Kit for Serious Outback Work
Been running this Toughdog lift kit on my Colorado 7 for six months now, including a recent Cape York trip and multiple Simpson Desert crossings. The upgraded struts and heavy-duty shocks handle corrugations significantly better than stock, and there's noticeably less body roll when loaded up with recovery gear and long-range tanks. Ride quality on highway is still comfortable enough for the family, but it's the off-road performance where this kit really proves its worth.(5)
Perfect Upgrade for Our Family Adventures
Fitted this Toughdog lift kit to our Colorado 7 before our last trip up to the High Country and it's completely transformed how the wagon handles with the roof topper and kids' gear loaded up. The ride quality is noticeably better on corrugated tracks, and the missus even commented how much more comfortable it feels compared to the worn-out factory setup. Well worth the investment for anyone doing regular family camping trips – it's built tough and you can really tell the difference when you're loaded up.(5)
Transformed my work rig completely
Been running this Toughdog lift kit on my Colorado 7 for about 6 months now, carting tools and materials to sites daily plus weekend trips down the coast. The ride quality is actually better than stock even with a full load in the back, which surprised me. Installation was straightforward and everything lined up perfectly, no dramas at all.(5)
