The Dobinsons Nitro Gas 4" Lift Kit is built specifically for the Toyota Land Cruiser 79 Series (1999-ON), using nitrogen gas-charged twin-tube shock absorbers matched to heavy-duty multi-leaf leaf springs front and rear. The nitro gas shock design limits fluid aeration on long corrugated runs, so damping stays consistent whether you're running a steel tray, canopy or camper trailer. This kit delivers a genuine 4" lift for bull bar, winch and larger tyre clearance while keeping the factory leaf-sprung front axle geometry intact. Every kit ships from Australian stock with a full Dobinsons manufacturer warranty and fitment support from our suspension team.

Single Cab Models: After 08/2016 Lower Front Crossmember Under Tailshaft needs to be modified to allow clearance.
Lift height compliance: A lift of this height may exceed your state's allowable limit without engineering certification. Check your state's light vehicle modification rules (VSB14/NCOP) before fitting.
Choosing the right leaf spring rate depends on the constant accessory weight sitting on the axle, not just the vehicle model. A 79 Series carrying a steel tray, bull bar, winch, long-range fuel tank, dual battery tray and drawer system needs a firmer rear leaf pack than a stock cab-chassis running light touring gear. Tell our team your bull bar brand, canopy or tray weight, water/fuel capacity and typical load, and we'll help you match a spring rate that sits level and rides properly both loaded and unloaded.
Fitment should be carried out by a qualified 4WD suspension installer or an experienced DIY mechanic with a hoist, given the leaf spring and shackle work involved. Wheel alignment is mandatory after fitting a 4" lift kit, as castor and toe angles shift with the added ride height. Allow a 500km bedding-in period for the new leaf packs and shock bushes to settle before a final alignment check. The 79 Series locates its solid front axle with radius arms and a panhard rod rather than IFS control arms, so pair this kit with caster correction (adjustable radius arms or high-angle caster bushes) and an adjustable front panhard rod to restore steering feel and re-centre the axle at the new ride height.
Dobinsons is an Australian-designed suspension brand tested locally on the conditions 79 Series owners actually drive — corrugations, sand, mud and long-haul touring routes. Every Nitro Gas shock and leaf spring in this kit is backed by a full Dobinsons manufacturer warranty. Tradespeople and tourers running heavy 79 Series setups have relied on the Dobinsons catalogue for years — view the full Dobinsons range for other applications.
Full manufacturer specifications are available on the official Dobinsons website.
This kit suits tradespeople running a steel tray, toolboxes and a canopy who need the ride height to hold up under constant load, and tourers fitting a camper trailer or roof-top tent who want stable clearance without a harsh unladen ride. If your accessory load still sags the rear beyond what the leaf spring rate handles, our airbag suspension range can add load-levelling support on top of this kit.

Yes - this kit fits the Toyota LandCruiser 79 Series from 1999 onward: Single Cab models with the 4.2L 1HZ diesel (1999-ON) or 4.5L 1VD-FTV V8 turbo diesel (2007-ON), and Dual Cab models (2012-ON, V8). Spring and damping rates are selected to suit your accessory load, so confirm your build date and setup with our team, or check compatibility through our parts finder before ordering.
This kit provides a genuine 4" lift front and rear on the 79 Series, achieved through heavy-duty leaf spring assemblies matched to Nitro Gas shocks of the correct length for that ride height. The lift is measured at the axle relative to factory ride height, not just at the guard line. Actual ride height will vary slightly depending on your accessory load, particularly rear tray or canopy weight. We can advise on expected ride height for your specific accessory combination.
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 Nitro Gas shock absorbers, 2 front and 2 rear heavy-duty leaf spring assemblies built for a 4" lift, greasable shackle pins and bushes, a front and rear U-bolt kit with mounting plates, brake line extension brackets, and full fitting hardware with instructions. Caster correction components (offset radius arm bushes or adjustable radius arms), an adjustable front panhard rod, extended brake lines and a steering damper are not included and are sold separately. Everything needed to mount the springs and shocks to the factory 79 Series axle points is in the box.
Yes, this kit is built for 79 Series vehicles carrying constant accessory load and towing, which is the primary reason Dobinsons offers heavy-duty leaf spring options for this platform. The leaf spring rate needs to be matched to your typical towing and payload combination to sit correctly under load. Tell our team your caravan or trailer ball weight along with your tray and bull bar weight so we can confirm the right leaf pack. Getting the spring rate right prevents rear sag and keeps headlights aimed correctly while towing.
The 79 Series has a solid front axle on coil springs, located by radius arms and a panhard rod, so there are no upper or lower control arms to upgrade like an IFS vehicle. At a 4" lift caster correction is essential, using adjustable radius arms or high-angle caster bushes, along with an adjustable front panhard rod, extended brake lines and a driveline angle check. On single cab models after 08/2016 the lower front crossmember under the tailshaft also needs modification for clearance.
Yes, wheel alignment is mandatory after fitting this 4" lift kit. Raising the vehicle by 4" changes castor and toe angles enough to affect tyre wear and steering feel if left unchecked. We recommend an alignment straight after fitment, then a follow-up check after the 500km bedding-in period once the new leaf springs and shock bushes have settled. Skipping alignment is the most common cause of premature tyre wear on lifted 79 Series vehicles.
Yes, Dobinsons offers different leaf spring rate options for the 79 Series depending on your constant accessory load, and our team can recommend the right pack based on your tray, canopy, bull bar, winch, fuel and water tank weight. A lighter tourer running minimal gear needs a different rate to a tradesperson running a loaded steel tray and toolboxes every day. Contact us with your accessory list before ordering so we can confirm the spring rate matches this kit or point you to an alternative Dobinsons rate. Getting this right avoids a sagging rear end or an overly harsh unladen ride.
A 4" lift on the 79 Series typically opens up clearance for larger tyre sizes than stock, but the exact size that clears depends on your wheel offset, tyre width and whether you're running flares. We recommend confirming your intended tyre and wheel combination with our team before fitting, particularly if you're also running a wider track or aftermarket wheels. Rubbing points to check include the inner guard liner and any factory mudflaps at full steering lock. We can talk through tyre clearance based on similar 79 Series builds we've supported.
This kit comes with a full Dobinsons manufacturer warranty covering the Nitro Gas shock absorbers and leaf spring assemblies against manufacturing defects. Warranty terms are handled directly through 4WD Suspension as your Australian supplier, so you're not dealing with an overseas distributor if a claim comes up. Keep your invoice and fitment date on file, as most warranty claims require proof of purchase. Contact our team if you have any warranty questions before or after fitting.
Yes, the Dobinsons Nitro Gas shock and leaf spring combination is designed to keep the 79 Series comfortable on-road as well as capable off-road, provided the spring rate matches your typical daily load. A 79 Series running an unladen daily commute with a lighter leaf rate will ride more comfortably than one fitted with a heavy-duty pack sized for constant towing. This is exactly why spring rate selection matters — get it matched to how you actually drive the vehicle day to day. Our team can advise on the best-riding combination for your use case.
