Selecting the correct spring rate is critical for achieving optimal ride quality and preventing premature component wear. When ordering, you must select spring rates based on your current constant load only — this means accessories and equipment permanently installed on your vehicle, not occasional loads like camping gear or towing loads. Common front constant loads include steel bullbars, winches, long-range fuel tanks, and heavy-duty batteries. Rear constant loads typically include steel rear bars, dual battery systems, drawer systems, water tanks, and permanently mounted camping equipment. Occasional weekend camping gear and towing loads should NOT be factored into spring rate selection, as this will result in overly stiff springs causing harsh ride quality and potential damage to other suspension components.
Professional installation by a qualified 4WD suspension specialist is strongly recommended for this 3" lift kit due to the complexity of the installation and mandatory modifications required. Post-installation, a full four-wheel alignment is absolutely essential to correctly set castor, camber, and toe angles for safe handling and even tyre wear. All shock absorbers require a 500km break-in period for seals to bed in and oil to circulate through valving — initial ride quality will improve noticeably after this period. For Gladiators carrying heavy constant loads or used extensively for towing, consider pairing this kit with upgraded control arms for additional strength and improved suspension geometry at lifted heights.

IMPORTANT WARNING – 75MM (3") LIFT KIT COMPLIANCE: This 3" lift kit is designed primarily for off-road use. Before fitting to a registered road vehicle, you must refer to your local state and territory vehicle modification regulations. An engineering certificate may be required in most Australian states for lifts exceeding 50mm (2"). Vehicle handling characteristics will change with lifts above 50mm — increased body roll, altered braking dynamics, and changed centre of gravity are normal. Additional modifications may be required including extended brake hoses, modified bump stops, driveline modifications, and steering component upgrades depending on your specific vehicle configuration and local regulations. 4WD Suspension Australia does not accept responsibility for injury to persons or property resulting from improper installation or use of this product contrary to local laws.
This kit is specifically engineered for Jeep Gladiator JT models from 2018 onwards with the 3.6L V6 petrol engine. It fits all JT variants including Sport, Overland, and Rubicon models with the factory coil spring suspension setup. The kit includes all necessary hardware, castor correction components, and sway bar extensions for proper fitment. If you're unsure about your specific build date or have aftermarket modifications already installed, our suspension experts can confirm exact compatibility — just contact us with your VIN number for verification.
This kit delivers a genuine 75mm (3 inches) of suspension lift height measured at the wheel arches when fitted to a standard unloaded Jeep Gladiator JT. Actual lift height will vary slightly depending on the spring rates you select and your vehicle's constant accessory load — heavier front bars and winches may reduce front lift by 10-20mm compared to a bare vehicle. The 3-inch lift enables fitment of up to 35-inch tyres (depending on wheel offset) and provides substantial ground clearance improvement for serious off-road touring. Combined with larger tyres, you'll achieve approximately 4-5 inches of total ride height increase compared to factory specification.
This comprehensive kit includes everything needed for a complete front and rear suspension upgrade: four Dobinsons MRA adjustable remote reservoir shock absorbers (two front, two rear), four precision-matched coil springs with 75mm lift rating, front castor correction kits to restore proper steering geometry, and both front and rear sway bar extension kits. All mounting hardware and brackets are included for installation. Upper control arms, extended brake lines, and bump stop extensions are NOT included but may be required depending on your specific application and local regulations — our team can advise on any additional components needed for your build.
Yes, this MRA adjustable kit is excellent for towing applications thanks to the 3-way damping adjustment system that allows you to firm up compression damping when loaded. When towing caravans or trailers, you can increase low-speed compression to reduce squat and improve stability, then return to softer settings for unladen comfort. The kit's spring rates should be selected based on your constant rear accessory load (not towing weight), and spring selection is critical for maintaining proper ride height. For regular heavy towing or carrying significant rear loads, consider adding airbag suspension to the rear for additional load support and the ability to level your vehicle when hitched up to maintain optimal towing geometry.
This kit includes front castor correction components which adjust the factory control arms to restore proper steering geometry after lifting. For most Gladiator owners, the included castor correction is sufficient for a 3-inch lift with normal use. However, if you're building an expedition vehicle with extreme articulation requirements, planning aggressive rock crawling, or want maximum suspension travel, aftermarket adjustable upper control arms are recommended for fine-tuning geometry and preventing component binding at full droop. Heavy-duty lower control arms may also be beneficial for vehicles subjected to severe off-road use or carrying very heavy constant loads. Our suspension specialists can advise whether control arm upgrades are necessary for your specific application and driving style.
Yes, a full four-wheel alignment by a qualified suspension specialist is absolutely mandatory after installing any lift kit, including this Dobinsons system. The 3-inch lift height significantly alters your vehicle's suspension geometry, affecting castor, camber, and toe angles which directly impact steering feel, tyre wear, and vehicle stability. The included castor correction kits must be properly adjusted during alignment to restore factory-spec castor angles for predictable on-road handling. Failure to perform proper alignment after installation will result in premature tyre wear (especially inner edge wear), wandering steering, and potentially unsafe handling characteristics. Budget for a quality 4WD-specialist alignment when planning your installation costs, as this is not optional.
Spring rate selection is based exclusively on your constant accessory load — equipment permanently fitted to your vehicle that's always present during normal driving. For the front, calculate the combined weight of your bullbar, winch, long-range fuel tank, upgraded battery, and any permanently mounted accessories. For the rear, include rear bar, drawer systems, dual battery setups, water tanks, and fixed camping equipment. Do NOT include occasional loads like camping gear you remove between trips, or towing loads, as this will result in overly stiff springs and harsh ride quality. If you're between spring rates or planning to add more accessories soon, it's generally better to select the slightly heavier spring rate. Contact our team with your specific accessory list and we'll recommend the optimal spring rates for your exact setup.
With this 3-inch Dobinsons lift kit fitted to your Jeep Gladiator JT, you can comfortably run up to 35-inch tyres (285/75R17 or 315/70R17) with appropriate wheel offset and minimal to no trimming required for most driving conditions. Some minor trimming of inner fender liner or heat shield may be necessary at full lock and full compression depending on your specific wheel offset and tyre width. For the best fitment without rubbing, choose wheels with approximately -12 to +12mm offset. If you want to run 37-inch tyres, additional modifications including fender trimming, aftermarket fenders, or body lift may be required. Remember that larger, heavier tyres will affect your Gladiator's acceleration, braking distance, and fuel economy, and may require speedo recalibration and potentially regearing for optimal performance.
Dobinsons backs this MRA adjustable lift kit with a comprehensive manufacturer warranty covering defects in materials and workmanship. Shock absorbers typically carry a 2-year warranty, while coil springs and hardware components are covered for defects. Warranty coverage requires professional installation by a qualified technician and proper maintenance including the 500km break-in period and adherence to recommended service intervals. Warranty does NOT cover damage resulting from improper installation, use contrary to manufacturer specifications, accident damage, competition use, or normal wear and tear from usage. Always retain your proof of purchase and installation receipts. For specific warranty terms and conditions or to make a warranty claim, contact us directly and we'll guide you through the process.
While this Dobinsons MRA kit delivers exceptional on-road ride quality for a 3-inch lift system thanks to its advanced adjustable damping, there are important considerations for daily driving. Vehicle handling characteristics do change with any lift exceeding 50mm — expect increased body roll in corners, slightly longer braking distances due to higher centre of gravity, and different steering feel compared to factory height. The 3-way adjustable shocks allow you to dial in a comfortable highway setting for daily commuting, then firm up for off-road adventures. Some Australian states require engineering certification for lifts over 50mm on registered road vehicles, which may involve inspections and documentation. If your Gladiator is primarily a daily driver with occasional off-road use, consider whether a 2-inch lift might better balance on-road comfort with off-road capability while avoiding engineering requirements.
Perfect Setup for Serious Remote Touring
Been running this Dobinsons 3-inch lift on my Gladiator through the Simpson Desert and Cape York, and it's absolutely transformed the truck. The adjustable remote reservoir shocks are brilliant for fine-tuning between corrugations and rock work, something you really need when you're days from civilisation. Fitment was spot-on with quality components throughout, and the ride quality loaded up with touring gear is better than stock ever was.(5)
Perfect Upgrade for Our Family Camping Adventures
Just got back from a two-week trip through the High Country and this Dobinsons 3-inch lift kit absolutely transformed how our Gladiator handles both on the highway and off-road. The adjustable shocks are brilliant – we ran them softer for the corrugated tracks and firmed them up when loaded with the camper trailer and all the kids' gear. Ride quality is leagues better than the old setup, and the missus actually commented on how much more comfortable the long drives are now. Well worth every dollar for anyone who actually uses their truck properly.(5)
Perfect Upgrade for My Outback Adventures
Just finished installing the Dobinsons 3" MRA kit on my Gladiator and couldn't be happier with the transformation. The adjustable damping is a game-changer when switching between daily driving around Melbourne and weekend trips out to the High Country. Ride quality is surprisingly plush on-road while still handling corrugations like a dream, and the team at 4WD Suspension Australia had it delivered within days with all the hardware needed.(5)
