Choosing the correct spring rate is critical for optimal performance and depends on your constant front-end accessory load. Common front accessories that affect spring selection include bull bars (30-60kg), winches (30-40kg), steel or aluminium replacement bumpers, driving lights, UHF aerials, and roof racks. Measure your total constant load and select springs rated 100-150kg above your base load to maintain proper ride height and suspension travel. For heavy touring setups exceeding 150kg constant load, contact our team to discuss custom spring rate options.
Professional installation by a qualified mechanic or experienced 4WD workshop is strongly recommended to ensure correct fitment, torque specifications, and safety. Wheel alignment is mandatory after installation to prevent premature tyre wear and maintain optimal steering geometry. Allow a 500km break-in period for springs to settle and dampers to bed in before final ride height assessment. For Colorado RG models lifted beyond 40mm, we recommend pairing these struts with upgraded adjustable control arms to correct castor angle and maintain factory steering feel and tyre wear characteristics.
Toughdog has earned its reputation as Australia's number one suspension brand through decades of engineering excellence, extensive real-world testing across outback tracks and mining sites, and unwavering commitment to quality.

These assembled struts are ideal for Holden Colorado RG owners who have added significant front-end accessories, regularly tow caravans or trailers, or need to restore factory ride height after years of wear. They're equally suited to touring enthusiasts seeking improved off-road articulation, tradespeople requiring heavy-duty load capacity for tools and equipment, and daily drivers wanting superior comfort and handling. For those carrying heavy constant rear loads in the tray, consider pairing with airbag suspension to maintain level stance and optimal towing geometry under all load conditions.

These Toughdog assembled struts are specifically engineered for all Holden Colorado RG models from 2012 through 2020, including both pre-facelift and post-2017 facelift variants. They fit all trim levels including LS, LT, LTZ, and Z71 variants with both the 2.5L and 2.8L diesel engines. The struts are designed to bolt directly into factory mounting points using existing hardware locations. If you have a modified Colorado or aftermarket suspension components already fitted, please contact our team to confirm compatibility before ordering.
The lift height achieved depends on the spring rate selected and your vehicle's constant front-end load. Typically, these struts provide between 25-50mm of front lift compared to worn factory suspension. Lighter spring rates may provide more lift on unloaded vehicles, while heavier-rated springs maintain ride height under significant accessory loads like bull bars and winches. The primary purpose is to restore factory stance when loaded or level the vehicle's rake for improved towing geometry. For specific lift measurements based on your Colorado's configuration, our suspension experts can recommend the optimal spring rate.
This package includes a complete pair of fully assembled front struts for the Holden Colorado RG. Each strut comes pre-assembled with premium coil springs, top strut mounts with bearings, bump stops, dust boots, and all necessary mounting hardware and washers. The struts arrive ready to install, saving significant workshop time compared to purchasing components separately. Installation instructions are included, though professional fitting is strongly recommended. Note that wheel alignment, extended brake lines, and potentially longer sway bar links may be required depending on the final lift height achieved.
Yes, these Toughdog struts are specifically valved and sprung to handle the demands of regular towing. The upgraded damping characteristics and firmer spring rates significantly reduce front-end dive under braking when towing caravans or trailers, improving control and safety. The enhanced load capacity prevents front-end sag from heavy towball downloads, maintaining proper steering geometry and headlight alignment. For optimal towing performance, we recommend pairing these front struts with upgraded rear suspension components matched to your typical towing weight. Many Colorado owners who regularly tow 2500-3500kg report dramatically improved stability and confidence compared to factory suspension.
Control arm upgrades are not mandatory for lift heights under 40mm, but they become increasingly beneficial as lift height increases. Factory control arms can accommodate the moderate lift these struts provide, but adjustable upper control arms allow precise castor angle correction to maintain factory steering feel and prevent accelerated tyre wear. If you're planning to fit larger tyres (32 inches or above) or want maximum steering precision and performance, upgraded control arms are highly recommended. They also provide improved bush quality and durability for heavy touring applications. Our team can assess your specific setup and advise whether control arms should be part of your upgrade path.
Yes, wheel alignment is absolutely mandatory after installing these struts and must be performed by a qualified workshop with 4WD alignment experience. Any change to suspension geometry affects camber, castor, and toe settings, and these parameters must be reset to manufacturer specifications to prevent premature tyre wear and ensure safe handling. The alignment should be performed after the vehicle has been driven approximately 100-200km to allow springs to settle into their working position. Most reputable 4WD workshops include alignment in their installation quote, and skipping this critical step will void your suspension warranty and create unsafe driving conditions.
Yes, Toughdog offers multiple spring rate options for the Colorado RG front struts to accommodate different constant loads. When ordering, you can specify your front-end accessory weight, and we'll supply struts with appropriately rated springs. Common spring rates range from medium-duty for lightly accessorised Colorados up to heavy-duty options for vehicles with full bull bars, winches, and significant additional weight. It's important to calculate your total constant front load honestly — bull bars typically add 40-60kg, winches add 30-40kg, and steel bumpers can add 50-80kg. Our team can help you select the optimal spring rate during checkout or via phone consultation.
These struts primarily restore ride height and improve performance rather than provide extreme lift for massive tyres. With the typical 25-50mm lift achieved, most Colorado RG owners can comfortably fit up to 32-inch tyres without extensive modifications, though minor trimming of inner guards may be required depending on wheel offset. For 33-inch tyres or larger, additional modifications including body mount chops, guard trimming, and potentially diff drop brackets may be necessary. The lift also depends on your selected spring rate and constant load. We recommend consulting with a 4WD workshop familiar with Colorado modifications to plan your complete wheel and tyre upgrade strategy.
All Toughdog suspension components are backed by the manufacturer's comprehensive warranty, which covers defects in materials and workmanship under normal operating conditions. The specific warranty period varies by component but typically ranges from 12 months to lifetime coverage depending on the part. Warranty coverage requires professional installation, proof of purchase, and compliance with break-in and maintenance requirements. The warranty does not cover damage from accidents, racing, overloading beyond rated capacity, or incorrect installation. Full warranty details are included with your shipment, and our team can explain the specific terms applicable to this strut assembly before purchase.
Absolutely — these Toughdog struts are engineered to provide excellent on-road comfort while delivering improved capability for touring and off-road use. Unlike harsh heavy-duty shocks designed purely for commercial applications, these foam cell struts offer well-damped, compliant ride quality that makes daily commuting comfortable while still controlling body roll and maintaining stability when loaded. Many Colorado RG owners report ride quality equal to or better than factory suspension, especially when factory shocks have accumulated significant kilometres. The key is selecting the appropriate spring rate for your typical load — correctly matched springs deliver the best balance between comfort, control, and load capacity for mixed-use vehicles.
