When upgrading to MRA adjustable shocks, selecting the correct rear spring rate is crucial for optimal performance based on your typical load configuration. Calculate your constant accessory weight including steel bullbar, winch, dual battery system, roof rack, full water tanks, camper or canopy weight, drawer systems, second spare tyre, and typical cargo load. For D-Max owners who frequently tow caravans exceeding 2000kg or carry 300kg+ payload, consider pairing these shocks with heavy-duty leaf springs or supplementary airbag suspension for maximum load support and level ride height.
Professional installation by a qualified 4WD suspension specialist is strongly recommended to ensure correct fitment, torque specifications, and initial damping setup. Remote reservoir mounting requires careful routing to avoid heat sources and potential snag points during extreme articulation. Four-wheel alignment is mandatory after installation to verify suspension geometry and prevent premature tyre wear. Allow 500km break-in period before making fine adjustment changes, as bushings and components settle during initial use. For vehicles with significant lift heights exceeding 50mm, consider upgrading to extended control arms to restore factory caster angle and maintain steering geometry.

Yes, these Dobinsons MRA adjustable rear shocks are specifically engineered for all 4th generation Isuzu D-Max models from 2020 onwards, including SX, LS-M, LS-U, LS-T, X-Terrain, and X-Rider variants. They're compatible with both stock suspension and vehicles fitted with 25-50mm lift kits. The shocks are designed to work with the factory rear leaf spring setup or upgraded heavy-duty leaf packs. If you've made significant modifications to your suspension geometry or are running custom spring configurations, we recommend contacting our technical team to confirm fitment and spring rate compatibility.
These are raised shock absorbers designed to accommodate lift heights between 25-50mm when paired with appropriate lifted springs. The shocks themselves don't provide lift — lift height is determined by your spring selection (coil springs at front, leaf springs at rear for D-Max). The "raised" designation means these shocks have extended travel and mounting lengths to work properly with lifted suspension, preventing bottoming out and maintaining optimal damping through the full range of suspension travel. Installing these shocks on stock-height springs will not raise your vehicle.
This kit includes a pair (2 units) of Dobinsons MRA monotube remote reservoir rear shock absorbers with all necessary mounting hardware and remote reservoir brackets. Each shock features pre-installed adjustment knobs on the remote reservoir body for easy damping changes. The kit includes protective sleeving for the reservoir hoses, comprehensive installation instructions, and a damping adjustment chart to help you dial in perfect settings. You'll also receive full manufacturer warranty documentation. Note that this is a rear shock package only — front shocks, springs, and other suspension components are sold separately.
Absolutely — the MRA monotube remote reservoir design makes these shocks exceptionally well-suited for heavy towing applications. The remote reservoir provides superior heat dissipation during sustained highway towing, preventing damping fade that occurs with standard twin-tube shocks. The 20-stage low-speed compression adjustment allows you to dial in firmer damping when towing to reduce body roll and rear squat, then soften them when running unloaded for comfortable daily driving. For D-Max owners regularly towing caravans exceeding 2500kg or experiencing significant rear sag, we recommend pairing these shocks with airbag suspension for optimal load support and level ride height under all conditions.
Control arm upgrades are not mandatory for shock replacement, but they become highly recommended when installing suspension lifts exceeding 50mm. The D-Max uses independent front suspension with control arms that affect caster and camber angles — when you lift the vehicle significantly, these angles change and can cause steering wander, poor handling, and accelerated tyre wear. If you're installing a complete lift kit with 50mm+ lift height, extended or adjustable control arms restore proper suspension geometry. For stock height or modest lifts under 40mm with these raised shocks, factory control arms typically remain adequate, though a professional alignment is always required after any suspension work.
Yes, a full four-wheel alignment is absolutely mandatory after installing any new suspension components, including shock absorbers. Even though you're only replacing rear shocks, the installation process involves loosening suspension mounting points which can shift alignment settings. More importantly, if you're installing these raised shocks as part of a lift kit with new springs, your suspension geometry will change significantly, affecting camber, caster, and toe angles. Proper alignment ensures even tyre wear, optimal handling characteristics, and safe vehicle dynamics. Book your alignment with a shop experienced in 4WD suspension who can verify all angles are within manufacturer specifications for lifted or modified vehicles.
While these shocks come as a set pair, you should definitely select appropriate rear leaf spring rates when building a complete suspension system. Dobinsons offers various rear leaf spring options for the D-Max with different load ratings to match your typical accessory weight and towing requirements. Calculate your constant load including canopy/camper weight, drawer systems, dual batteries, and typical cargo, then select springs rated for that load range. The beauty of MRA adjustable shocks is their ability to work across a wide range of spring rates — you can fine-tune damping to match whatever springs you choose, whether light touring springs or heavy-duty commercial-rated leaf packs for maximum payload capacity.
Tyre fitment depends on your total lift height (determined by spring selection) rather than the shocks themselves. With a 40mm lift kit paired with these raised shocks, most D-Max owners can fit 32-inch tyres (265/70R17 or 265/65R18) without modifications. A 50mm lift typically allows 33-inch tyres with minor trimming of plastic guards. Important factors include wheel offset, tyre width, and specific tread pattern — some aggressive mud terrains are wider than their size suggests. For precise tyre fitment advice based on your specific wheel and lift combination, consult with our team who can provide guidance based on hundreds of D-Max builds. Remember that larger tyres may require speedo recalibration and can affect gear ratios and fuel economy.
Dobinsons MRA shock absorbers are backed by comprehensive manufacturer warranty covering defects in materials and workmanship. The specific warranty period and terms are detailed in the documentation included with your kit. Dobinsons has built its reputation on standing behind its products, and these fully rebuildable shocks represent a long-term investment in your vehicle's capability. The "rebuildable for life" design means that even after warranty expiration, these shocks can be professionally serviced with new seals, oil, and internal components to restore like-new performance — unlike disposable shocks that must be completely replaced. Warranty coverage requires professional installation and proper maintenance, so retain your installation receipts and documentation.
These MRA shocks excel in both daily driving and serious off-road applications — that's precisely why the adjustability is so valuable. Set them softer (lower compression damping) for comfortable daily commuting with excellent bump absorption and ride quality that rivals or exceeds factory shocks. Dial them firmer when loading up for weekend trips, towing your caravan, or hitting corrugated outback tracks where increased damping prevents excessive body movement and maintains control. Most D-Max owners find a middle-ground setting that works well for typical mixed use, then make minor adjustments for specific scenarios. The monotube design delivers consistent performance whether you're cruising highway kilometres to work or navigating technical tracks in the High Country — you don't sacrifice on-road comfort for off-road capability.
Perfect upgrade for my work D-Max
Been running these Dobinsons adjustable shocks on my 2021 D-Max for about three months now and they've completely transformed the rear end. Loaded up with tools and materials every day, the ride is so much more planted and comfortable compared to stock. The adjustability means I can fine-tune them whether I'm empty or fully loaded, which is brilliant for someone who's constantly changing payloads.(5)
Perfect Upgrade for Our Loaded D-Max
These Dobinsons adjustable shocks have completely transformed our 2021 D-Max for family camping trips. The rear end no longer sags when we load up the camper trailer and all the gear, and the ride quality on corrugated tracks is noticeably smoother than the standard shocks. Fitment was straightforward and they've handled everything from beach sand to High Country tracks without missing a beat. Well worth the investment for anyone who regularly tours with a loaded rig.(5)
