Choosing the correct spring rate is critical to achieving optimal ride quality, load capacity, and component longevity. Spring rates must be selected based on your constant accessory load — the weight permanently fitted to your vehicle when empty of passengers and cargo. Common front accessories include steel bullbars (30-50kg), winches (30-40kg), long-range fuel tanks, upgraded batteries, and heavy-duty intercoolers. Rear constant loads include steel canopies or hard lids (60-120kg), drawer systems (50-80kg), dual battery setups, long-range fuel tanks (empty weight), toolboxes, and fixed water tanks. Do not select spring rates based on occasional loads such as passengers, camping gear, firewood, or towing — these are variable loads that should not dictate your spring rate. Over-springing results in harsh ride quality, accelerated wear on bushings and shock absorbers, and reduced traction off-road.
Professional installation by a qualified 4WD suspension specialist is strongly recommended to ensure correct fitment, torque specifications, and safety compliance. This kit requires standard hand tools, spring compressors, and jack stands — expect 4-6 hours labour for experienced installers. A full four-wheel alignment is mandatory after installation to restore factory camber, caster, and toe settings, preventing uneven tyre wear and maintaining steering precision. Bilstein recommends a 500km break-in period during which springs will settle 5-10mm and shock damping characteristics will stabilise — avoid harsh off-road use during this period. For vehicles with heavy bullbar and winch setups, consider pairing this kit with upgraded control arms to correct castor angle and improve steering feel and high-speed stability.

Explore the complete Bilstein suspension range for shocks, steering dampers, and complete lift solutions engineered for your specific vehicle.
This lift kit is ideal for Holden Colorado RG owners seeking a reliable 2-inch lift for touring, recreational off-roading, and improved towing capability without sacrificing daily driving comfort. It's perfect for tradespeople requiring stable load-carrying performance with toolboxes and equipment, grey nomads towing caravans across the Nullarbor, weekend warriors tackling High Country tracks, and families fitting roof tents or roof racks for camping adventures. If you regularly carry heavy rear loads or tow at maximum GVM, consider supplementing this kit with airbag suspension for on-demand load adjustment and level ride height when loaded.

This kit is specifically engineered for Holden Colorado RG models manufactured between 2012 and 2020, covering both the 2.5L and 2.8L turbo diesel engines across all body styles including Space Cab and Crew Cab. It suits 4x4 and 4x2 variants with factory coil front and leaf rear suspension. If your Colorado has been previously modified with aftermarket suspension or factory air suspension, please contact our team to confirm compatibility. For peace of mind, check our detailed fitment table or use our online parts finder tool to verify your exact model and year.
This Bilstein kit delivers a 2-inch (approximately 50mm) lift at both the front and rear of your Colorado RG, measured when the vehicle is unladen. Actual lift height will vary slightly depending on your constant accessory load — vehicles with heavy bullbars and winches may sit 40-45mm higher at the front, while those with canopies and drawer systems may achieve 45-50mm at the rear. After the recommended 500km break-in period, springs will settle 5-10mm as they compress to their working height. This lift height provides clearance for 32-33" tyres with minimal trimming while maintaining safe steering geometry and driveline angles.
The complete kit includes 2 x Bilstein B6 monotube front shock absorbers, 2 x King Springs heavy-duty front coil springs, 2 x Bilstein B6 rear shock absorbers, 2 x heavy-duty rear leaf springs, 4 x HD U-bolts, and 1 x polyurethane bush kit with all necessary mounting hardware. Spring rates for both front and rear are selectable at checkout based on your constant accessory load. This kit does not include extended brake lines, upper control arms, differential drop components, or wheel alignment — these may be required depending on your vehicle's existing setup and final ride height. All components are Australian-delivered stock with full manufacturer warranty.
Yes, this Bilstein B6 kit is highly suitable for towing applications when correctly spring-rated for your constant loads. The monotube shock design provides superior damping control and reduced squat under towball weight compared to factory twin-tube shocks, improving caravan stability and reducing sway during highway travel and windy conditions. When ordering, select rear spring rates based on your constant rear accessories only — not your towing weight, as the towball load is variable. For Colorado owners who regularly tow at or near maximum capacity, we recommend supplementing this kit with airbag suspension for on-demand rear height and load adjustment. Always ensure your total vehicle weight including accessories and tow load remains within Colorado's GVM and GCM ratings.
Upper control arm upgrades are not mandatory for a 2-inch lift on the Colorado RG, but they are highly recommended if you're running a heavy front-end setup with steel bullbar, winch, and long-range tank. Aftermarket upper control arms with additional castor correction restore steering feel, reduce understeer, and improve high-speed stability after lifting. They also provide adjustability for fine-tuning wheel alignment and compensating for load-induced geometry changes. If you're running a lighter front end or primarily use your Colorado for urban driving and light touring, the factory control arms will suffice. For serious off-road touring or heavy towing, upgraded arms are a worthwhile investment in handling and safety.
Yes, a professional four-wheel alignment is absolutely mandatory after installing any lift kit, including this Bilstein setup. Lifting your Colorado alters suspension geometry, affecting camber, castor, and toe angles at both front and rear axles. Without proper alignment, you'll experience uneven and accelerated tyre wear, steering pull to one side, reduced steering precision, and compromised handling safety. Your alignment technician should reset all angles to manufacturer specifications or apply slight positive castor for improved highway stability. Always perform the alignment after the kit has been installed and the vehicle has been loaded to its typical operating weight, and recheck alignment after the 500km break-in period once springs have fully settled.
Yes, this kit offers selectable spring rates for both front and rear to match your specific constant accessory load, and you must select the appropriate rates during checkout. Front spring options accommodate different weights of bullbars, winches, intercoolers, and auxiliary batteries, while rear options suit canopies, drawer systems, dual batteries, water tanks, and toolboxes. It's critical that you select spring rates based only on permanent accessories fitted to the vehicle when empty — do not factor in passengers, camping gear, firewood, or towing loads, as these are variable. Over-springing causes harsh ride quality and accelerated wear on bushings, shocks, and chassis mounts. If unsure, contact our team with a list of your accessories and their weights for personalised spring rate recommendations.
With this 2-inch Bilstein lift kit installed, your Colorado RG will comfortably accommodate 32-inch tyres with standard offset wheels and minimal clearance issues. Many owners successfully run 265/70R17 or 265/75R16 tyres with no trimming required. If you're planning to fit 33-inch tyres (285/70R17 or 285/75R16), expect minor trimming of front mudflaps and plastic inner guards, particularly at full steering lock and under compression during off-road articulation. Wheel offset and backspacing also play a critical role — aggressive negative offset wheels will push tyres outward and increase the likelihood of rubbing. Always test fitment with full steering lock, full suspension compression, and loaded vehicle weight before committing to final tyre and wheel selection.
All Bilstein shock absorbers included in this kit are covered by Bilstein's comprehensive manufacturer warranty, which protects against defects in materials and workmanship under normal use conditions. King Springs front coil springs and the heavy-duty rear leaf springs carry their own manufacturer warranties for structural failure and breakage. Polyurethane bushings and hardware components are also warranty-backed. Warranty claims require proof of purchase and evidence that the kit was professionally installed and correctly spring-rated for your vehicle's constant load. Warranties do not cover wear and tear from incorrect installation, overloading beyond GVM, or damage from improper spring rate selection. Retain all purchase receipts and installation invoices for warranty validation.
Absolutely — this Bilstein B6 kit is engineered to deliver a comfortable, controlled ride for daily driving, highway cruising, and urban commuting while also providing the durability and performance needed for off-road touring. Bilstein's monotube gas shocks feature velocity-sensitive damping that adapts to road conditions, staying soft over small bumps and speed humps while firming up during hard cornering and emergency braking. King Springs coils are progressive-rate designs that balance load support with ride compliance, avoiding the harshly over-sprung feel of cheaper kits. When correctly spring-rated for your accessories, this kit will match or exceed factory ride comfort while significantly improving load capacity, towing control, and high-speed stability. Thousands of Colorado owners rely on this setup for everything from school runs to cross-country adventures.
