Choosing the correct spring rate is critical to achieving optimal ride quality and avoiding premature component wear. When placing your order, select spring rates based on your constant accessory load only — this means weight that is permanently fitted to your vehicle, not occasional loads like camping gear or towing. Common front constant loads include bull bars, winches, long-range fuel tanks, heavy-duty batteries, and upgraded steel bumpers. Rear constant loads typically include steel trays, canopies, toolboxes, dual spare wheel carriers, and permanently mounted water tanks. Occasional loads such as camping equipment, temporary cargo, and towing do not constitute constant load — selecting overly heavy spring rates will result in a harsh, uncomfortable ride and may cause stress to other suspension components. Our team can assist with spring rate selection if you provide details of your vehicle setup.
Professional installation by a qualified 4WD suspension specialist is strongly recommended to ensure correct fitment, torque specifications, and safety compliance. This kit requires removal and replacement of front coil springs and rear leaf springs, plus shock absorber installation — typical installation time is 4-6 hours. A full wheel alignment is mandatory after installation to restore correct castor, camber, and toe settings, preventing uneven tyre wear and maintaining steering stability. Allow a 500km break-in period for springs to settle and shocks to bed in before making final adjustments to the IMS damping settings. Depending on your lift height and accessory weight, you may also benefit from upgraded control arms to restore suspension geometry and improve wheel travel.

If you regularly carry near-maximum payload or tow close to your vehicle's towing capacity, consider pairing this kit with airbag suspension for on-demand load support and level towing without compromising unladen ride quality.

This kit is specifically engineered for 3rd generation Mazda BT-50 Dual Cab models manufactured from September 2020 onwards (TF series). It fits all engine variants including the 3.0L turbo diesel. If you have an earlier model BT-50 (2011-2020 or pre-2011), this kit will not fit — please contact us to find the correct kit for your year. You can verify your vehicle's build date on the compliance plate or by using our online parts finder tool.
This Dobinsons Monotube IMS kit delivers 40-50mm of lift height depending on your vehicle's current accessory load and the spring rates you select. Vehicles with heavier constant loads (bull bars, winches, steel trays, canopies) will sit toward the lower end of the range, while lightly accessorised vehicles will achieve closer to 50mm. The lift is sufficient to accommodate 32-33 inch tyres with minimal trimming on most BT-50 setups. Final ride height also depends on tyre size, wheel offset, and suspension settling over the first 500km.
The kit includes everything needed for a complete front and rear suspension upgrade: 2 x IMS adjustable front monotube shocks, 2 x load-rated front coil springs, 2 x IMS rear monotube shocks, 2 x raised multi-leaf rear springs, 4 x heavy-duty U-bolts, 1 x polyurethane leaf spring bush kit, plus all necessary hardware and fitting instructions. Note that upper control arms, extended brake lines, and castor correction components are not included but may be required depending on your lift height and intended use — our team can advise on complementary upgrades when you order.
Yes, this Dobinsons IMS kit is an excellent choice for towing applications thanks to the adjustable front shocks, uprated spring rates, and raised leaf springs that restore ride height under load. The monotube shock design provides superior heat dissipation and fade-free performance during extended highway towing, while the adjustable damping allows you to firm up the front end for better stability when loaded. For frequent heavy towing (3000kg+), we recommend pairing this kit with airbag suspension in the rear for on-demand load levelling and enhanced weight distribution. Select your spring rates based on constant tray/canopy weight, not towing weight.
Upper control arm upgrades are not mandatory for a 40-50mm lift on the Mazda BT-50, but they are highly recommended to restore optimal suspension geometry, improve wheel travel, and prevent premature ball joint wear. Upgraded control arms with increased castor correction will also improve highway stability and steering feel, particularly when carrying heavy front-end accessories like bull bars and winches. If you plan to run the full 50mm lift with 33" tyres and engage in serious off-road touring, upgraded control arms will maximise the performance and longevity of your suspension system. Contact our team for a package price on control arms with this kit.
Yes, a full four-wheel alignment is absolutely mandatory after installing any lift kit. Changing spring heights and shock absorbers alters your vehicle's castor, camber, and toe settings, which will cause rapid uneven tyre wear, poor handling, and wandering on the highway if not corrected. Take your BT-50 to a qualified 4WD alignment specialist who can adjust to Dobinsons' recommended specifications for lifted vehicles. Alignment should be performed after the initial 500km break-in period once springs have fully settled, then rechecked after the first 5000km. Keep your alignment records for warranty purposes.
Yes, this kit offers multiple spring rate options for both front coil springs and rear leaf springs to match your exact constant accessory load. When ordering, you'll be prompted to select spring rates based on the permanent weight you carry — this includes items like bull bars, winches, long-range tanks, steel trays, canopies, and toolboxes that are always on the vehicle. It's critical to select only your constant load, not occasional camping gear or towing weight, as oversized spring rates will result in a harsh ride and potential damage to bushes, shock mounts, and chassis. Our team can help calculate your load and recommend the correct spring combination for your setup.
With this Dobinsons 40-50mm lift kit, most Mazda BT-50 Dual Cabs can accommodate 32 inch tyres with little to no trimming, and 33 inch tyres with minor guard trimming and appropriate wheel offset. Actual tyre clearance depends on your wheel width, offset, and whether you've fitted a bull bar or other accessories that limit steering lock. We recommend staying with a +20 to +30 offset wheel and testing full steering lock and compression articulation before committing to your final tyre choice. For maximum clearance, combining this lift with upper control arms will improve wheel travel and reduce the chance of tyre contact with guards during extreme articulation.
Dobinsons provides a comprehensive manufacturer warranty on all components in this kit, subject to correct installation by a qualified technician and appropriate use. Shock absorbers and springs are covered against manufacturing defects, with warranty periods varying by component — typically 12-24 months for shock absorbers and longer for springs. Warranty requires proof of professional installation, wheel alignment records, and adherence to the 500km break-in and service schedule. Dobinsons has an Australia-wide warranty support network, and our team can assist with any warranty claims or technical support throughout the life of your suspension. Keep all receipts and service records for warranty validation.
Absolutely — this Dobinsons Monotube IMS kit is engineered to deliver exceptional daily driving comfort while also providing superior off-road capability when needed.

Unlike budget lift kits that compromise on-road comfort, Dobinsons suspension is proven by thousands of Australian tourers who cover 20,000+ highway kilometres annually between remote destinations. Whether you're commuting to work Monday to Friday or towing a van to Cape York, this kit delivers the versatility modern BT-50 owners demand.
Perfect Setup for Remote Outback Touring
Been running this Dobinsons IMS lift kit on my BT-50 for six months now, covering everything from the Simpson Desert to Cape York, and it's absolutely transformed the truck. The monotube shocks handle corrugations brilliantly while still being compliant enough over rocks, which is exactly what you need when you're 500km from the nearest town. Build quality is top-notch and the adjustability means I could dial it in perfectly for my dual battery setup and rooftop tent.(5)
Perfect Setup for Our Family Adventures
Been running this Dobinsons IMS lift kit on our BT-50 for six months now, doing regular trips down to Wilsons Prom and out through the High Country with the family. The ride quality is genuinely impressive – loaded up with camping gear, roof tent, and the kids in the back, it handles corrugated dirt roads so much better than the stock setup ever did. Really happy with how it's transformed the whole driving experience, especially on those long gravel stretches where you're covering serious distance.(5)
