Selecting the correct spring rate is critical for achieving optimal ride height, comfort, and component longevity - always base your selection on constant accessory load only, not occasional loads. Common front accessories include steel bull bars (30-60kg), winches (30-40kg), long-range fuel tanks, and upgraded batteries. Rear constant loads include drawer systems (50-100kg), dual battery setups, water tanks, canopies or hardtops, and permanently mounted recovery gear. Important: Occasional loads such as camping gear, passengers for weekend trips, or periodic towing should NOT be factored into spring rate selection - choosing overly stiff springs for occasional use results in harsh ride quality, accelerated wear on bushings and shock mounts, and potential damage to other suspension components. When ordering, accurately assess only the accessories and equipment permanently fitted to your LandCruiser.
Professional installation by an experienced 4WD workshop is strongly recommended for this lift kit, as it requires specialized spring compressors, safety equipment, and knowledge of LandCruiser-specific installation procedures. A full 4-wheel alignment is mandatory after installation to ensure correct camber, caster, and toe settings - preventing premature tyre wear and maintaining safe handling characteristics. Allow a 500-kilometer break-in period for springs to settle and shocks to bed in before making final ride height assessments or spring rate adjustments. For vehicles with significant lift, we recommend upgrading to heavy-duty adjustable control arms to correct front-end geometry, restore proper ball joint angles, and maximize the performance and lifespan of your new suspension system.
Dobinsons has earned its reputation as one of Australia's most trusted suspension manufacturers through decades of engineering excellence, rigorous outback testing, and unwavering commitment to quality.

Backed by comprehensive warranty coverage and supported by a nationwide network of specialist dealers and installers, the Dobinsons suspension range is the choice of professional tour operators, mining fleets, emergency services, and serious adventurers who demand proven performance.
This 4-inch lift kit is ideal for LandCruiser owners who demand serious capability: remote area tourers tackling the Canning Stock Route or Cape York, tradespeople carrying heavy equipment to remote job sites, caravan towers needing enhanced stability and load capacity, and off-road enthusiasts running 35-inch tyres and comprehensive touring setups. If you regularly carry heavy constant loads or tow large caravans, consider pairing this kit with airbag suspension for additional load support and on-the-fly ride height adjustment. Whether you're building the ultimate tourer or need reliable performance for daily trade use, this Dobinsons kit delivers the ground clearance, load capacity, and durability your LandCruiser demands.

Yes, this kit is specifically engineered for all Toyota LandCruiser 80 Series (1990-1998) and 105 Series (1998-2007) models with solid front axle configuration. It fits both petrol and diesel variants across all trim levels. The kit includes model-specific shock absorbers and coil springs designed to work perfectly with the LandCruiser's suspension geometry. If you have modified suspension components or are unsure about your vehicle's exact specifications, contact our team to confirm fitment before ordering.
This Dobinsons kit delivers approximately 100mm (4 inches) of lift over standard ride height when installed with appropriate spring rates for your vehicle's accessory load. Actual lift height can vary by 10-20mm depending on the spring rate selected, your vehicle's constant accessory load, and initial condition of your existing suspension. The kit provides clearance for significantly larger tyres (up to 35 inches with minor trimming) and dramatically improves ground clearance for serious off-road use. Remember that springs will settle 10-15mm during the first 500 kilometers of use.
This complete kit includes 2 front Dobinsons nitro gas shock absorbers, 2 heavy-duty front raised coil springs, 2 rear nitro gas shock absorbers, and 2 rear raised coil springs - everything needed for front and rear suspension lift. You can select custom spring rates at checkout to match your specific constant accessory load. The kit does NOT include upper control arms, extended brake lines, steering dampers, or installation hardware, which may be required depending on your vehicle's configuration. We recommend consulting with a professional installer to identify any additional components needed for your specific build.
Yes, this Dobinsons kit is excellent for towing applications, with heavy-duty rear springs designed to handle increased payload and towing loads without excessive squat. The nitro gas shocks provide superior damping control under load, improving stability and braking performance when towing caravans or boat trailers. However, you must select rear spring rates appropriate for your towing setup if it constitutes a constant load (e.g., if you tow regularly). For occasional heavy towing or variable loads, consider adding airbag suspension to the rear for adjustable load support without compromising unladen ride quality.
While not absolutely mandatory, upgrading to adjustable upper control arms is strongly recommended with a 4-inch lift to correct front-end geometry and restore proper castor and camber angles. Without control arm correction, you may experience increased tyre wear, wandering steering, and reduced ball joint lifespan due to altered suspension geometry. Adjustable control arms allow your installer to dial in optimal alignment settings, improving on-road handling, steering returnability, and component longevity. Most experienced installers will recommend this upgrade for lifts over 2 inches to maximize performance and safety.
Yes, a full 4-wheel alignment is absolutely mandatory after installing any lift kit, including this Dobinsons system. Lifting your LandCruiser alters suspension geometry, affecting camber, castor, and toe settings across all four wheels. Without proper alignment, you'll experience rapid and uneven tyre wear, poor handling characteristics, and potentially dangerous steering behavior. The alignment should be performed after installation and the initial 500km settling period, and should be done by a workshop experienced with lifted 4WD vehicles who can adjust for the modified ride height.
Select spring rates based solely on your constant accessory load - the weight permanently installed on your vehicle. For the front, measure bull bar weight, winch, long-range fuel tank, upgraded batteries, and any permanent armor or protection. For the rear, include drawer systems, dual batteries, water tanks, canopy or hardtop weight, and fixed recovery gear. Do NOT include occasional loads like camping gear, passengers, or periodic towing when selecting spring rates. Choosing springs too stiff for your actual constant load results in harsh ride quality and accelerated wear on bushings and mounts. Our team can help you calculate your accessory weight if you're unsure.
With a 4-inch lift, you can typically fit tyres up to 35 inches in diameter on standard LandCruiser 80/105 Series wheels (16-inch), though minor trimming of plastic inner guards may be required for full articulation. Some owners successfully run 315/75R16 or 35x12.50R16 tyres with appropriate wheel offset and minimal modifications. Tyre fitment also depends on wheel offset, backspacing, and whether you've installed aftermarket control arms or other suspension modifications. Always test-fit and cycle suspension through full articulation before committing to extreme tyre sizes, and consult with your installer about specific tyre and wheel combinations.
Dobinsons provides comprehensive manufacturer warranty coverage on all components in this kit, protecting against defects in materials and workmanship under normal use conditions. Specific warranty terms vary by component type - shock absorbers and springs each have designated coverage periods. Warranty coverage requires professional installation with proof of purchase, and excludes damage from accidents, racing, or installation errors. As an authorized Dobinsons dealer, we fully support all warranty claims and can facilitate the process directly. Keep your invoice and installation records to ensure seamless warranty service if ever required.
Yes, despite the significant lift height, this Dobinsons kit is engineered to maintain acceptable daily driving comfort and highway manners when fitted with correctly-rated springs for your load. The nitro gas shocks provide excellent damping control for on-road stability, while the progressive spring rates balance off-road capability with civilized road behavior. However, any 4-inch lift will result in a firmer ride than stock, increased body roll compared to factory suspension, and slightly reduced highway refinement - this is the trade-off for extreme off-road capability and ground clearance. If you prioritize highway comfort over maximum lift, consider a 2-inch kit instead.
Proper Kit for Serious Remote Touring
Been running this Dobinsons 4-inch lift on my 105 for about 18 months now, covering everything from the Canning Stock Route to Cape York's roughest sections. The nitro gas shocks handle corrugations brilliantly and haven't faded even when loaded up with long-range tanks and roof gear. Fitment was spot-on and the ride quality is leagues ahead of the old setup – actually comfortable on highway runs but still controlled when things get nasty.(5)
Perfect Upgrade for Our Family Adventures
Been running this Dobinsons 4-inch lift kit for six months now and it's completely transformed our 105 for weekend trips up the coast and into the high country. The ride quality is noticeably better than the old worn setup, even with the camper trailer loaded up with all the kids' gear. Fitment was spot-on and the extra clearance has given me so much more confidence on rougher tracks.(5)
