While these shock absorbers are matched to work with factory or upgraded spring rates, selecting the correct spring rate for your Colorado 7 depends on your typical accessory load. Rear accessories that increase constant weight include bull bars with spare wheel carriers, roof racks with roof-top tents, dual battery systems, long-range fuel tanks, drawer systems, and fridges. For vehicles regularly carrying camping gear, trade tools, or towing caravans above 2000kg ATM, consider upgrading to heavy-duty rear springs to maintain optimal ride height and prevent shock bottoming.
Professional installation is recommended for these rear shock absorbers, though experienced DIY mechanics with appropriate equipment can complete the installation using standard hand tools and jack stands. A wheel alignment is not typically required when replacing shocks only, but should be performed if any other suspension components are replaced simultaneously. Allow a 500km break-in period for seals and valving to settle before making any ride quality assessments. For Colorado 7 owners installing complete lift kits, consider pairing these shocks with upgraded control arms to correct suspension geometry and maintain safe handling characteristics.
Toughdog has earned its reputation as Australia's number one suspension brand through decades of real-world testing across the harshest touring routes, mine sites, and agricultural properties. Every Toughdog shock absorber is engineered to withstand extreme temperature variations, corrugated roads, and heavy load conditions that Australian 4WD owners face daily. Backed by comprehensive manufacturer warranty and trusted by commercial operators, touring families, and tradespeople nationwide, the complete Toughdog suspension range delivers proven durability you can rely on.
These Toughdog rear shock absorbers are ideal for Colorado 7 owners who regularly tow caravans or trailers, carry heavy cargo loads, or tour on rough unsealed roads where suspension durability is critical. Commercial operators using the Colorado 7 as a fleet vehicle will appreciate the extended service life and reduced maintenance costs. Families heading remote with camping gear, water tanks, and recovery equipment will benefit from improved rear-end stability and reduced body roll. For maximum load support when hauling near GVM limits, pair these shocks with airbag suspension for on-demand ride height adjustment and load levelling capability.

These Toughdog rear shock absorbers are specifically engineered to suit the Holden Colorado 7 (RG series) wagon models manufactured between 2012 and 2016, including all LT and LTZ variants. They are designed as direct OEM replacements with no modifications required for installation. The shocks fit both 2WD and 4WD configurations of the Colorado 7 seven-seat wagon. If you own a Colorado dual-cab ute rather than the Colorado 7 wagon, different part numbers apply, so please verify your vehicle type before ordering or contact our team for confirmation.
These Toughdog rear shock absorbers are designed as performance replacement dampers and do not provide any lift on their own. Vehicle lift height is determined by your springs (coil or leaf springs), not the shock absorbers. These shocks are engineered with extended travel to accommodate lifted setups when paired with raised springs, typically supporting lift heights from factory up to 50mm. If you're looking to increase your Colorado 7's ride height, you'll need to upgrade your rear springs in conjunction with these shocks for optimal performance and safety.
This kit includes a matched pair of Toughdog rear shock absorbers (left and right sides) complete with mounting bushes and hardware required for installation. Each shock features nitro gas charging, corrosion-resistant coating, and protective dust boots. The kit comes with detailed fitment instructions and Toughdog warranty documentation. Upper and lower mounting hardware is included, though in some cases original mounting bolts may be reused depending on condition. This is a shocks-only package – springs, U-bolts, and other suspension components are sold separately.
Yes, these Toughdog rear shock absorbers are specifically engineered for heavy-duty applications including towing caravans and trailers. The nitro gas monotube design maintains consistent damping performance under load, preventing rear-end sag and improving stability when towing at or near your vehicle's rated capacity. The heavy-duty valving controls body roll and pitch during acceleration, braking, and cornering with a trailer attached. For maximum towing performance and load support, consider pairing these shocks with upgraded heavy-duty rear springs or airbag suspension to maintain optimal ride height under varying load conditions.
Control arm upgrades are not required when replacing shock absorbers only with factory-height springs. However, if you're installing these shocks as part of a complete lift kit with raised springs (typically 40mm or more), upgraded control arms become important to correct suspension geometry and maintain proper wheel alignment. Lifted vehicles without corrected control arms can experience increased tyre wear, reduced steering precision, and compromised handling safety. For Colorado 7 lift kits, we recommend consulting with our suspension specialists to determine whether control arm upgrades should be included in your suspension package based on your intended lift height.
Wheel alignment is generally not required when replacing shock absorbers only, as shocks do not affect alignment angles like camber, caster, or toe settings. However, if you're replacing these shocks as part of a broader suspension upgrade that includes springs, control arms, or other geometry-altering components, a full four-wheel alignment is mandatory. Even for shock-only replacement, it's good practice to have your alignment checked if your vehicle hasn't been aligned recently or if you've noticed uneven tyre wear. Professional installers will typically recommend an alignment check as part of any major suspension work to ensure optimal handling and tyre life.
These Toughdog rear shock absorbers are valved to work effectively across a range of spring rates, from factory specifications through to heavy-duty constant-load springs. The shock's progressive damping valving adapts to different spring stiffness levels while maintaining ride quality and control. When selecting spring rates for your Colorado 7, consider your typical payload and accessory weight – items like roof-top tents, drawer systems, dual batteries, long-range tanks, and towing equipment all add constant load that requires stiffer springs. Our team can recommend optimal spring rate combinations matched to these shocks based on your specific vehicle setup and intended use.
These shock absorbers alone do not increase ground clearance or tyre fitment capability, as lift height is determined by your springs, not your shocks. However, these extended-travel shocks are designed to accommodate lifted setups when paired with raised springs, which can then allow for larger diameter tyres. The Colorado 7 can typically fit up to 265/65R17 tyres (approximately 31 inches) with a modest 40-50mm suspension lift without requiring major modifications like guard trimming. For tyre fitment advice specific to your intended lift height and wheel offset, consult with our suspension experts who can recommend the complete package needed to safely run your desired tyre size.
Toughdog shock absorbers are backed by a comprehensive manufacturer's warranty covering defects in materials and workmanship under normal operating conditions. The specific warranty period and terms are detailed in the documentation included with your kit and vary based on application type (recreational vs commercial use). Toughdog's Australian-based warranty support ensures quick response times and local replacement stock availability if required. Warranty coverage requires professional installation or documented DIY installation following manufacturer specifications, and does not cover damage from accidents, modifications, or improper installation. Keep your purchase receipt and installation records to validate warranty claims if needed.
Absolutely – these Toughdog rear shock absorbers are engineered to excel in both daily driving and touring conditions, making them ideal for Colorado 7 owners who use their vehicle as a family wagon throughout the week and adventure vehicle on weekends. The progressive valving delivers compliant ride quality over small road imperfections during urban commuting while providing firm control during highway towing and outback touring. Unlike hardcore competition shocks that sacrifice on-road comfort, Toughdog's design philosophy prioritises versatile all-around performance. Many Colorado 7 owners report improved ride quality compared to worn factory shocks, with better control over corrugations and when carrying loads without compromising everyday comfort.
