The Dobinsons IMS Monotube Lift Kit suits the Toyota LandCruiser 300 Series (2021-ON) and delivers an adjustable 2"-3" lift using the Independent Monotube Suspension (IMS) front strut design paired with monotube rear shock absorbers. Billet upper control arms correct camber and caster angles at ride height, while raised coil springs front and rear carry bar work, camping gear and touring accessories without sagging. This is a premium, adjustable lift kit for the 300 Series platform, backed by Dobinsons' manufacturer warranty and dispatched from Australian stock with fitment support from our team.

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 front and rear spring rate based on the constant weight you carry, not just peak load. Front loads to account for include bull bars, winches and driving lights, while rear loads include drawer systems, fridges, water tanks, dual batteries and canopy or tray weight. Tell our team your typical accessory list and we can confirm the right spring combination for your 300 Series before you order.
This kit involves strut and shock replacement, spring changes and control arm swaps, so we recommend an experienced 4WD suspension workshop rather than a driveway DIY install. A wheel alignment is mandatory after fitting to reset camber, caster and toe to spec at the new ride height. Allow a 500km bedding-in period for the monotube shocks and springs to settle before final alignment checks. Pairing this kit with the included upgraded control arms is what allows the geometry correction, so we don't recommend fitting the struts and springs without them.
Dobinsons has built 4WD suspension in Australia for decades, and the IMS system for the 300 Series was developed specifically around the factory IFS front end rather than adapted from another platform. Kits are backed by a manufacturer warranty and are used by tourers and tradespeople running accessory-heavy setups. You can view the full Dobinsons range to compare this kit against other Dobinsons options for the 300 Series.
This kit suits 300 Series owners who tow, tour or carry a genuine accessory load and want the geometry corrected properly rather than just fitting taller springs. It's built for long-distance travellers and tradespeople who need consistent damping under sustained rough-road use. If your load varies significantly trip to trip, also look at airbag suspension to fine-tune rear ride height on the fly.
This kit is in stock in Australia and dispatched fast from our warehouse, with our team on hand to confirm fitment for your specific 300 Series build. Browse our full lift kit range or get in touch before you order.

This Dobinsons IMS Monotube Lift Kit is built for the Toyota LandCruiser 300 Series from 2021-ON, covering GXL, VX, Sahara, Sahara ZX and GR Sport variants fitted with the 3.3L V6 twin turbo diesel. The IMS front strut design is matched to the factory IFS front end used across this range. If you're unsure about a specific variant or accessory setup, our team can confirm fitment before you order.
This kit provides a 2" to 3" lift front and rear on the 300 Series, adjustable within that range through the IMS strut and spring seat setup. The exact height within the 2"-3" window depends on the spring rate chosen to suit your accessory load. Our team can help you land closer to 2" or closer to 3" based on what you're carrying.
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 x Dobinsons IMS monotube front strut assemblies, 2 x monotube rear shocks, raised front and rear coil springs, and 2 x billet aluminium upper control arms with associated mounting hardware. Full fitting instructions are included. Lower control arms and diff drop kits are not included and are sold separately if your alignment specialist recommends them.
Yes, the raised rear coil springs and monotube rear shocks are suited to towing setups where a tow ball load adds constant weight over the rear axle. The monotube shock design resists fade better than a twin-tube shock when running loaded over long distances. Tell us your typical tow ball weight and we'll confirm the right rear spring rate.
Billet aluminium upper control arms are included as part of this kit, so no separate control arm purchase is needed for the front end. These arms are what allow the camber and caster correction at the 2"-3" lift height. Running the struts and springs without them is not something we recommend, as factory arms can't correct the geometry shift at this height.
Yes, a wheel alignment is mandatory after installing this kit. Lifting the vehicle changes camber, caster and toe angles, and the billet control arms need to be set correctly at ride height to avoid uneven tyre wear. We recommend the alignment be done after a 500km bedding-in period once the springs and shocks have settled.
Dobinsons offers front and rear spring options to suit different constant accessory loads on the 300 Series, from bull bars and winches up front to drawers, fridges and canopy weight out back. Tell our team your typical loaded weight and we'll match the spring rate to it rather than guessing. Getting this right keeps the vehicle sitting at the intended 2"-3" height rather than sagging.
A 2"-3" lift on the 300 Series generally clears larger tyre diameters than standard, but exact tyre size clearance depends on wheel offset and width as well as lift height. We recommend confirming your intended tyre and wheel combination with our team before ordering so we can advise on clearance at your chosen ride height.
This kit is backed by Dobinsons' manufacturer warranty, covering the IMS struts, rear shocks, springs and control arms against manufacturing defects. Warranty terms are honoured through 4WD Suspension in Australia, so you're not dealing with an overseas claims process. Contact our team directly if you ever need to make a claim.
Yes, the IMS monotube design is set up to retain a compliant on-road ride at the correct spring rate for your load, not just an off-road-only setup. Many 300 Series owners run this kit as a daily driver that also tows and tours. Matching the spring rate to your actual daily load, rather than an unladen setup, is what keeps the ride comfortable on-road.
