Lift height compliance: Suspension lifts of this size may exceed your state's allowable limit without engineering certification. Check your state's light vehicle modification rules (VSB14/NCOP) before fitting.
Choose your spring rate based on what's permanently fitted to the tray or tub, not just what you carry occasionally. A Gladiator running a canopy, dual battery system, bullbar and winch needs a firmer rear leaf and front coil than a stock tub used for weekend touring. Common accessories that add constant load include steel bullbars, winches, canopies, drawer systems, long-range fuel tanks and rooftop tents — tell our team what's fitted and we'll help match the correct spring rate.
This is a bolt-on kit best fitted by an experienced 4WD suspension installer or a qualified DIY mechanic with a workshop hoist and spring compressor. Wheel alignment is mandatory after fitting to reset castor, camber and toe at the new ride height. Allow a 500km bed-in period for the springs to settle before a final alignment check. Consider pairing this kit with upgraded control arm upgrades to maximise front axle articulation and correct pinion angle further at 3" of lift.
Dobinsons designs and tests its suspension in Australia, working with local fitment feedback across the ute and 4WD market rather than relying on overseas-only development. This MRA kit carries a manufacturer warranty and is backed by our own Australian fitment support team for spring rate and installation questions. Tradespeople and remote-area tourers running Gladiators specify Dobinsons for the adjustability and remote-reservoir cooling — view the full Dobinsons range for other Gladiator-compatible components.
This kit suits Gladiator JT owners running a canopy or tray accessories for work, tourers fitting rooftop tents and drawer systems, and anyone wanting adjustable damping to switch between unladen and loaded driving. If you're regularly carrying uneven or heavy loads and want load-levelling on top of this kit, our airbag suspension range can be added to the rear leaf springs.

Yes — this Dobinsons 3" MRA kit is built specifically for the Jeep Gladiator JT from 2018 onward, covering both the 3.6L Pentastar V6 petrol and 3.0L EcoDiesel V6 variants. It uses vehicle-specific front coil springs, rear leaf springs and shock absorber dimensions matched to the JT's chassis and axle mounts. If you're unsure of your exact build date or accessories fitted, our fitment team can confirm compatibility before you order. You can also check fitment using our Gladiator parts finder.
This kit provides a 3" lift front and rear on the Gladiator JT, achieved with taller front coil springs, rear leaf springs and longer-travel MRA shock absorbers. Actual ride height gain can vary slightly depending on vehicle load and accessories already fitted. The 3-way adjustable damping changes compression and rebound feel only — it doesn't alter ride height. If you need a different lift height, ask our team about other Dobinsons options for the Gladiator.
Please note that all assembled struts are dispatched at a height based on our experience and the manufacturer’s specifications for the advertised lift. Coil springs and leaf springs are also manufactured according to the advertised height and constant-load rating. Actual vehicle height may vary depending on the vehicle and the weight of fitted accessories. Further adjustment may therefore be required after installation. The installer may use coil spacers or adjust the struts at their discretion to achieve the desired height. We are not responsible for vehicle-specific height variations or any additional adjustments required after installation.
The kit includes 2 front and 2 rear Dobinsons MRA adjustable shock absorbers with remote reservoirs, front coil springs, rear leaf spring assemblies, castor-correction bushes, front sway bar extension links and the mounting hardware required for installation. Upper and lower control arms are not included and are sold separately. Full fitting instructions are supplied with the kit. Contact us if you'd like a quote on matching control arms for your build.
Yes, the rear leaf springs in this kit can be matched to your constant accessory and tow-ball load, and the 3-way adjustable shocks let you firm up damping when towing. Tell our team what canopy, drawers or bullbar you're running so we can confirm the right rear spring for your tow setup. This helps avoid excessive sag or a harsh unladen ride. Combining this kit with airbag suspension is also an option if you tow heavy trailers regularly.
At a 3" lift, front control arm angles change enough that upgraded arms are worth considering for the Gladiator JT, particularly adjustable units that help correct caster further and improve axle articulation. The castor-correction bushes included in this kit address part of the geometry change, but they don't extend arm length like a full control arm upgrade. Many customers pair this kit with our control arm range for a more complete geometry correction. Ask our team whether your intended use — daily driving versus off-road touring — warrants the upgrade.
Yes, wheel alignment is mandatory after installing this kit. Ride height changes at both axles alter caster, camber and toe, and correct alignment is needed for even tyre wear and predictable steering. We recommend an alignment straight after fitting and a second check after the 500km bed-in period once the springs have settled. Skipping this step can accelerate tyre wear and affect handling.
Yes, Dobinsons offers front coil and rear leaf spring options to suit different constant loads on the Gladiator JT. If you're running a canopy, dual battery, long-range tank or drawer system permanently, a firmer rate keeps the tray or tub sitting level rather than sagging. Tell our fitment team your typical loaded weight and accessories fitted and we'll recommend the correct spring rate for your kit. This is worth confirming before you order rather than after fitment.
A 3" lift on the Gladiator JT typically opens up clearance for larger tyres than the factory fitment, though the exact size depends on wheel width, offset and whether any minor guard trimming is done. We recommend checking your intended tyre and wheel combination with our team before ordering to avoid rubbing at full articulation or steering lock. Sway bar extension links included in this kit help maintain bar clearance at the raised height. Confirming this detail upfront saves time at installation.
This kit is covered by Dobinsons' manufacturer warranty, which applies to the shock absorbers and springs supplied in the kit. Warranty claims are handled through 4WD Suspension as your Australian supplier, with our team able to assist with any fitment or product query. Keep your proof of purchase and fitment date for warranty reference. Contact us directly if you have any concerns after installation.
Yes, the 3-way externally adjustable damping on this Dobinsons MRA kit lets you soften the ride for unladen daily driving and firm it up when the Gladiator is loaded or towing. This adjustability is one of the main reasons the MRA range suits owners who use their Gladiator for both work and weekend touring. A correct spring rate selection for your typical load also plays a big part in daily ride comfort. Our fitment team can help you set damping and spring rate for your specific use case.
