When ordering this shock kit, it's critical to select spring rates based on your constant accessory load — not occasional or temporary loads. Constant load refers to accessories permanently fitted to your D-Max including bull bars, rear bars, side steps, drawers, dual battery systems, roof racks, canopies, tool boxes, long-range fuel tanks, water tanks, and communication equipment. Occasional loads like camping gear, passengers, or periodic towing should not influence spring rate selection as choosing overly heavy springs will result in harsh ride quality when unladen and may cause premature wear to other suspension components. Always calculate the combined weight of permanently fitted accessories and consult spring load charts before selecting rates.
Professional installation by a qualified 4WD suspension specialist is strongly recommended to ensure correct fitment, torque specifications and safety compliance. While experienced DIY mechanics can install these shocks with appropriate tools and workshop manual guidance, wheel alignment is mandatory after any suspension work to prevent premature tyre wear and ensure safe handling characteristics. A 500km break-in period is recommended where you avoid extreme off-road use, allowing bushings to settle and shock oil to circulate fully through all valving. For vehicles with 2+ inches of lift, consider pairing these rear shocks with upgraded control arms to restore camber and caster angles for optimal steering geometry and tyre wear.
Bilstein has been engineering world-leading monotube shock absorbers in Germany since 1954, with countless motorsport championships, OEM partnerships and extreme expedition validations proving their technology. The Bilstein suspension range is extensively tested across Australian outback conditions and backed by comprehensive manufacturer warranty and local technical support. Trusted by touring families, remote area workers, and professional expedition outfitters, Bilstein delivers the perfect balance of German precision engineering and real-world Australian durability.
This shock kit suits Isuzu D-Max RG owners who've installed or are planning a 0-3 inch lift kit and need rear shocks capable of handling constant heavy loads, regular towing of caravans or trailers, remote touring with camping gear, or tradespeople carrying tools and equipment daily. If you frequently carry loads exceeding 300kg in the tub or tow close to your vehicle's rated capacity, consider supplementing this suspension setup with airbag suspension for on-demand load support and level adjustment. Perfect for grey nomads, remote workers, trade professionals and adventure tourers who demand reliability far from assistance.
All Bilstein products are held in Australian stock for fast dispatch nationwide with expert technical support available to ensure you select the right components for your D-Max setup.

These Bilstein B6 Long Travel rear shocks are specifically engineered for the Isuzu D-Max RG (third generation) models manufactured from August 2020 onwards. They fit all RG variants including SX, LS-M, LS-U, LS-T, X-Terrain and X-Rider across single cab, space cab and dual cab body styles. These shocks are designed for vehicles with 0-3 inch suspension lifts and will not fit earlier D-Max generations (RA-7 or RC models). If you're unsure about your vehicle's build date or variant, check your compliance plate or contact our team for confirmation.
These Bilstein B6 Long Travel shocks do not provide lift themselves — they are designed to suit vehicles that already have or will be fitted with 0-3 inch lift springs. The 'long travel' designation refers to the extended stroke length that accommodates the increased suspension droop and compression range created by lifted coil or leaf springs. To achieve lift on your D-Max RG, you'll need to pair these rear shocks with appropriate lifted leaf springs or coil springs depending on your rear suspension configuration. The shocks maintain optimal damping control across the extended travel range that lifted springs create.
This kit includes a pair (2 units) of Bilstein B6 Long Travel monotube gas pressure rear shock absorbers specifically valved and dimensioned for the Isuzu D-Max RG 2020-onwards platform. The shocks feature zinc-plated piston rods, digressive valve technology, and high-performance seals as standard. This is a rear axle shock kit only — front shocks, springs (leaf or coil), bushings, U-bolts, control arms and other suspension components are sold separately. If you're building a complete suspension system, you'll need to order front shocks, springs and any other components required for your specific lift height and load requirements.
Yes, the Bilstein B6 Long Travel rear shocks are engineered to handle regular towing of caravans, trailers and boats up to your D-Max's rated towing capacity (typically 3500kg braked). The monotube design with high-pressure gas maintains consistent damping under load, preventing rear-end sag and providing stable, controlled handling when towing through corners, braking zones and rough roads. For optimal towing performance, ensure you've selected appropriate spring rates for your constant accessory load and consider adding airbag suspension for on-demand load leveling and additional rear-end support when hitched. The digressive valve technology automatically adjusts damping based on shock speed, providing comfort unladen while resisting bottoming when loaded.
Control arm upgrades are not mandatory when fitting these rear shocks, but they become increasingly beneficial as lift height increases beyond 2 inches. On the D-Max RG, lifting the vehicle can alter suspension geometry angles (camber and caster), potentially causing uneven tyre wear and compromised handling. Upgraded aftermarket control arms with adjustable or corrected geometry restore optimal alignment angles for lifted vehicles. If you're running a 0-2 inch lift for touring and load-carrying purposes, factory control arms are generally adequate when professionally aligned. For 2-3 inch lifts, particularly for vehicles used for highway towing or daily driving, aftermarket control arms are recommended to maximize tyre life and handling precision.
Yes, a full four-wheel alignment is mandatory after installing any suspension components including shock absorbers on your Isuzu D-Max RG. While shocks don't directly affect alignment angles like springs or control arms do, the installation process involves disconnecting suspension components that can shift alignment settings. Proper alignment ensures even tyre wear, optimal handling characteristics, and safe steering response. Most suspension specialists will include alignment in their installation quote. After alignment, a settling period of approximately 500km is recommended before a final alignment check to account for bushing compression and spring settling, ensuring your D-Max tracks straight and tyres wear evenly.
When ordering this Bilstein B6 rear shock kit, spring rate selection refers to the leaf springs or coil springs you'll be pairing with these shocks — not the shocks themselves. The shocks are valved to suit a range of spring rates within the 0-3 inch lift category, but you must select springs based on your constant accessory load (permanently fitted equipment like bull bars, canopies, drawers, tanks, etc.). It's critical to select spring rates that match your actual constant load rather than overestimating for occasional loads like camping gear or periodic towing. Selecting overly heavy spring rates will result in harsh ride quality when unladen and may stress other suspension components, while selecting too-light springs will cause sagging and bottoming under your actual load.
These rear shocks are designed for 0-3 inch lift applications, which typically allows fitment of 32-33 inch tyres on the D-Max RG without rubbing (depending on wheel offset and specific lift height). The increased suspension travel provided by long travel shocks helps prevent tyre contact with guards during compression and articulation. However, tyre clearance depends on multiple factors including your exact lift height, wheel offset, tyre width, and whether you've fitted wider aftermarket guards or flares. For 33+ inch tyres, minor trimming of plastic guard liners or bumper tabs may be required. Always test-fit tyres through full suspension compression and steering lock before committing to a tyre size, and ensure your speedo is recalibrated for accuracy and legal compliance.
Bilstein B6 shock absorbers are covered by Bilstein's comprehensive manufacturer warranty against defects in materials and workmanship. The standard warranty period is typically 2 years or 40,000km (whichever occurs first) from the date of purchase for recreational use, though specific warranty terms can vary based on application and usage. Warranty coverage requires proof of purchase and installation by a qualified professional following manufacturer specifications. The warranty does not cover damage caused by misuse, accident, incorrect installation, or normal wear items. As an authorized Bilstein dealer, we provide full warranty support and can assist with any claims or technical questions throughout your ownership.
Yes, the Bilstein B6 Long Travel shock kit is specifically engineered to balance off-road capability and load-carrying performance with acceptable daily driving comfort. While these shocks are optimized for lifted, loaded and touring applications rather than pure on-road luxury, Bilstein's digressive valve technology provides compliant damping over small road imperfections and speed humps while maintaining control during spirited driving and emergency maneuvers. If you've selected appropriate spring rates for your actual constant load (not overestimated), the ride quality will be firm but controlled — suitable for daily commuting, highway cruising and long-distance touring. Owners who rarely carry loads and prioritize maximum on-road comfort might prefer touring-specific shock options, but for most D-Max owners balancing work, towing and recreation, the B6 range delivers excellent all-round performance.
Perfect Upgrade for Our Family Adventures
Fitted these Bilstein long travel shocks to my 2021 D-Max before our last trip to the High Country and the difference is night and day. The rear end no longer sags with the camper trailer loaded up, and the kids actually stopped complaining about the bumpy corrugated roads. Well worth the money for anyone doing regular touring with a bit of weight on board.(5)
Perfect upgrade for my daily work truck
Had these Bilstein B6 long travel shocks fitted to my 2021 D-Max about three months ago and they've completely transformed how the ute handles with a loaded tray. The ride quality is noticeably smoother on corrugated dirt roads heading to job sites, and they've handled a couple of beach trips without any dramas. Well worth the money for anyone using their truck hard every day.(5)
Perfect Upgrade for Our Family D-Max
Fitted these Bilstein B6 long travel rear shocks to our 2021 D-Max before our recent trip down the Victorian High Country and the difference is night and day. The back end no longer wallows when loaded up with camping gear and the kids, and corrugations are so much more manageable now. Really impressed with how they've transformed the ride quality, especially when towing our camper trailer.(5)
