Selecting the correct spring rate is critical for achieving optimal ride quality and preventing component damage. Choose your spring load rating based on the constant weight of accessories permanently fitted to your D-Max, not occasional loads or towing equipment. Common front accessories include steel bull bars (30-50kg), winches (30-40kg), upgraded batteries and intercoolers. Rear constant loads include aluminium canopies (70-120kg), drawer systems (40-80kg), dual spare wheel carriers, long-range fuel tanks and roof-mounted solar/battery systems. Occasional loads such as camping gear, passengers, water tanks and trailer towing should NOT be factored into spring rate selection as this will result in an overly firm ride and potential component stress when unloaded.
Professional installation by a qualified 4WD suspension specialist is strongly recommended to ensure correct fitment, torque specifications and safety. A complete wheel alignment is mandatory after installation to prevent premature tyre wear and ensure proper steering geometry. All suspension components require a 500km break-in period during which springs will settle and shocks will bed in—final ride height is typically achieved after this initial settling period. For D-Max models fitted with heavy front accessories or planning significant upgrades, consider pairing this kit with upgraded control arms to correct caster angle and maintain optimal handling characteristics.
Bilstein has been the world's leading monotube shock absorber manufacturer since 1954, with their B6 range representing the benchmark for OE-replacement performance across global automotive and motorsport applications. Every Bilstein shock sold in Australia undergoes rigorous testing across outback corrugations, coastal salt exposure and extreme temperature variations to ensure it meets the demands of Australian touring and commercial use. This kit is backed by Bilstein's comprehensive manufacturer warranty and is trusted by professional tradespeople, grey nomad tourers and weekend adventurers who demand uncompromising quality. Explore the complete Bilstein suspension range for additional vehicle-specific options.
This kit is engineered for D-Max owners who want a reliable, comfortable lift solution for touring with roof-top tents and rooftop storage, tradespeople running constant tool loads and canopy setups, or recreational four-wheel drivers seeking improved clearance for beach, forest and outback tracks. If you regularly tow caravans or trailers, consider supplementing this kit with airbag suspension to manage variable rear loads and maintain level ride height while towing. Daily drivers will appreciate the balanced ride quality that makes this kit equally capable commuting on sealed roads and exploring remote destinations on weekends.

This Bilstein 2" lift kit is specifically engineered to fit Isuzu D-Max RT50 series models manufactured from June 2012 through to July 2020, including all Single Cab, Space Cab and Dual Cab body configurations. It is compatible with both LS-M, LS-U and SX variants across this model range. The kit does not fit the newer RG D-Max (July 2020 onwards) which requires a different suspension design. If you're unsure about your exact build date or variant, our fitment specialists can verify compatibility using your VIN number—simply contact us with your vehicle details for confirmation.
This kit provides approximately 50mm (2 inches) of lift height measured from factory ride height, though final lift can vary by 10-15mm depending on your selected spring rate and constant accessory weight. Vehicles with heavier front accessories like steel bull bars and winches may sit slightly lower within the lift range, while lighter setups may achieve the full 50mm or slightly more. All suspension components require a 500km break-in period during which springs will settle by approximately 5-10mm as they compress to their optimal operating height. Final ride height is typically achieved after this initial settling period and one wheel alignment adjustment.
This complete bolt-on kit includes everything required for a front and rear suspension upgrade: 2 Bilstein B6 monotube front shock absorbers, 2 King Springs front coil springs in your selected load rating, 2 Bilstein B6 rear shock absorbers, 2 heavy-duty rear leaf springs in your selected load rating, 4 heavy-duty U-bolts for leaf spring installation, 1 polyurethane bush kit, and all necessary mounting hardware. You will not need to purchase any additional suspension components to complete the installation. However, a professional wheel alignment is mandatory after fitment and is not included in the kit price.
Yes, this kit significantly improves towing stability and load-carrying capacity compared to factory suspension, thanks to the heavy-duty leaf springs and velocity-sensitive Bilstein damping that controls body roll and pitch during towing. However, spring rate selection must be based only on your constant accessory weight, not towing loads—selecting springs that are too heavy for your constant load will result in a harsh unladen ride. For D-Max owners who regularly tow heavy caravans or variable loads, we recommend supplementing this lift kit with airbag suspension which allows you to adjust rear ride height and spring rate on demand to suit loaded and unloaded conditions. This combination delivers the best of both worlds: a comfortable daily ride with the ability to support heavy towing loads when required.
Upgraded control arms are not mandatory for a 2-inch lift on the D-Max, as this moderate lift height generally maintains acceptable suspension geometry and caster angle. However, if your D-Max is fitted with heavy front accessories (steel bull bar and winch combination), or if you plan to fit larger tyres beyond 32 inches, aftermarket control arms can restore optimal caster angle and improve steering feel and high-speed stability. Control arms also provide additional clearance for larger tyres and can reduce stress on ball joints and bushings. Our suspension specialists can assess your specific setup and recommend whether control arm upgrades would benefit your build—contact us for personalised advice based on your accessories and intended use.
Yes, a professional four-wheel alignment is absolutely mandatory after installing any lift kit and must be performed by a qualified workshop with alignment equipment capable of adjusting caster, camber and toe settings. Changing your suspension ride height alters your vehicle's steering geometry, and without proper alignment you will experience premature and uneven tyre wear, reduced steering precision, and potential handling issues. The alignment should be performed after installation and torque-checking of all suspension components, and ideally rechecked after the initial 500km break-in period once springs have fully settled. Factor the cost of alignment (typically $150-$250 depending on your location) into your total installation budget.
Spring rate selection must be based exclusively on the constant weight of accessories permanently fitted to your vehicle—this includes items like bull bars, winches, canopies, drawer systems, dual batteries, long-range tanks and roof racks that remain on the vehicle at all times. Do not include the weight of passengers, camping gear, tools, water or towing equipment as these are variable loads. Weigh your front and rear constant accessories separately: light springs suit under 40kg front/80kg rear, medium springs suit 40-80kg front/80-150kg rear, and heavy springs suit 80kg+ front/150kg+ rear. If you're between ratings, it's generally better to select the lighter spring for improved ride comfort. Our team can help you calculate your exact accessory weight if you're unsure—accurate spring selection is critical for ride quality.
With a 2-inch lift, most D-Max models can accommodate 32-inch tyres (typically 265/70R17 or 265/65R18) with minimal or no rubbing, depending on wheel offset and tyre brand. Some aggressive tread patterns may require minor trimming of plastic inner guards at full steering lock. To fit 33-inch tyres comfortably, you may need additional modifications such as guard trimming, aftermarket control arms for increased clearance, or wheel spacers to push the tyre further from suspension components. Remember that larger tyres affect speedometer accuracy, gearing, fuel economy and braking performance—we recommend staying within 5% of factory rolling diameter unless you plan to regear your differential. Contact us for specific tyre and wheel combination advice for your D-Max model and year.
All Bilstein shock absorbers in this kit are covered by Bilstein's comprehensive manufacturer warranty which protects against defects in materials and workmanship—warranty period varies by component and application but typically ranges from 2-5 years depending on usage type. King Springs coil and leaf springs carry their own manufacturer warranty against breakage and defects. Warranty coverage requires professional installation with correct torque specifications, and is void if components are used outside their specified load ratings or with incompatible modifications. Polyurethane bushings and U-bolts are considered consumable items with limited warranty coverage. We recommend retaining your purchase receipt and installation records to facilitate any warranty claims, and our team can assist with warranty assessment and claims processing if required.
Absolutely—Bilstein B6 shock absorbers are specifically designed as a premium OE-replacement upgrade that improves ride quality over factory shocks while adding lift capability, making them ideal for vehicles used daily for commuting, highway touring and weekend off-road adventures. The monotube gas design with velocity-sensitive damping provides plush, controlled comfort on sealed roads while automatically firming up over corrugations and rough terrain. Ride quality will be directly influenced by your spring rate selection—choosing springs matched to your actual constant load ensures the suspension operates in its optimal range for comfort. Many D-Max owners report improved ride quality compared to worn factory suspension, with better control over load and towing without the harsh ride associated with heavy-duty leaf spring-only kits.
