Dobinsons IMS Monotube 2-3 Inch Lift Kit - Toyota Landcruiser 300 Series

This Dobinsons kit provides a 2 to 3 inch (approximately 50-75mm) lift for your Landcruiser 300 Series, with the exact height adjustable via the front strut spring seats. The final installed height will vary based on your chosen spring rates and constant accessory load—heavier front-end builds may sit slightly lower while lighter builds achieve closer to 3 inches. Rear lift is determined by spring rate selection and constant rear load. During installation, your fitter can fine-tune the front height to match your desired stance and ensure level front-to-rear geometry. Most 300 Series builds with typical touring accessories achieve approximately 60-70mm of lift with this kit.

This complete Dobinsons kit includes everything needed for a comprehensive suspension upgrade: 2 x IMS adjustable monotube front struts, 2 x front coil springs, 2 x IMS monotube rear shock absorbers, 2 x raised rear coil springs, 2 x adjustable billet aluminium upper control arms, 1 x adjustable rear panhard rod, 1 x rear swaybar link extension kit, plus all necessary mounting hardware and bushings. The kit addresses both suspension performance and geometry correction required when lifting the 300 Series. You'll need to select appropriate front and rear spring rates during ordering based on your constant accessory load—refer to the spring rate selection guide or contact our team for assistance choosing the correct rates for your build.

Absolutely—this Dobinsons IMS kit is engineered specifically for heavy towing applications when paired with correctly selected spring rates. The monotube shock technology provides fade-resistant damping control even when towing at maximum capacity in hot Australian conditions, while the load-rated coil springs maintain ride height and control under constant weight. However, it's critical to select spring rates based only on your constant accessory weight, NOT towing loads. For heavy or regular towing, we strongly recommend supplementing this kit with airbag suspension in the rear, which provides on-demand load support when towing while maintaining excellent unladen ride quality when the caravan is unhitched. This combination delivers the best of both worlds for serious tourers.

Yes, and this kit has you covered—it includes adjustable billet aluminium upper control arms specifically because they're essential for proper suspension geometry after lifting the Landcruiser 300 Series. When you lift the front of the 300, the standard control arms create incorrect caster angles that lead to wandering steering, reduced stability, and uneven tyre wear. The included adjustable upper control arms allow your installer to dial in correct caster and camber angles during wheel alignment, restoring proper geometry and actually improving steering feel over the standard setup. These billet arms are also significantly stronger than factory, making them ideal for off-road abuse and heavy-duty applications. No additional control arm purchase is necessary unless you're doing other modifications.

Yes, a full four-wheel alignment is absolutely mandatory after installing any lift kit on your Landcruiser 300 Series. Lifting the vehicle changes suspension geometry including caster, camber and toe angles, which will cause poor handling, tyre wear and potential safety issues if not corrected. The adjustable upper control arms included in this kit provide extended adjustment range to achieve correct alignment specifications after the lift. Your installer should perform the alignment immediately after fitting and allow components to settle for 500km, then recheck alignment as springs settle into their final height. Never skip this critical step—proper alignment ensures your 300 drives safely and handles properly both on-road and off-road.

Yes, this kit offers multiple front and rear spring rate options to match your specific constant accessory load, and selecting the correct rates is critical for ride quality and component longevity. During checkout you'll choose spring rates for both front and rear based on the permanent weight your 300 Series carries—items like bullbars, winches, drawer systems, dual batteries, replacement bumpers, and long-range tanks. It's essential to be honest about constant loads and avoid over-springing your vehicle by factoring in occasional camping gear or towing weights. If you overestimate and select springs that are too heavy, you'll experience harsh ride quality and potential damage to other suspension components. Our team can help you calculate your accessory weight and recommend appropriate spring rates—contact us if you're unsure before ordering.

Yes, this 2-3 inch lift significantly improves tyre clearance on the Landcruiser 300 Series, typically allowing fitment of 33 to 35 inch tyres depending on wheel offset, tyre width, and driving conditions. The adjustable panhard rod included in the kit centers the rear axle after lifting, ensuring equal clearance on both sides for larger tyres. However, final tyre fitment depends on multiple factors including wheel backspacing, tyre profile, whether you trim or remove inner guards, and your intended use (aggressive off-road articulation may still cause contact on extreme sizes). Most 300 Series owners find that 285/70R18 or 285/65R20 tyres fit well with this lift and no modifications, while 305mm width tyres may require minor trimming. We recommend test-fitting and articulating the suspension fully before committing to a specific tyre size for your build.

This Dobinsons IMS Monotube lift kit is backed by Dobinsons' comprehensive manufacturer warranty, covering materials and workmanship defects under normal use conditions. Dobinsons stands behind their Australian-engineered products with some of the industry's best warranty coverage, reflecting their confidence in build quality and durability. Warranty specifics vary by component type (shocks, springs, control arms) and are detailed in the documentation included with your kit. To maintain warranty coverage, the kit must be professionally installed or fitted by an experienced mechanic following proper procedures, and a wheel alignment must be performed after installation. For complete warranty terms and conditions, or if you experience any issues with your Dobinsons kit, contact our team and we'll assist you through the warranty process directly with Dobinsons.

Yes, this Dobinsons IMS kit excels as a daily driver suspension when paired with correctly selected spring rates for your build. The monotube IMS technology provides a balanced tune that maintains near-factory ride comfort on sealed roads while dramatically improving capability off-road and when loaded. Unlike budget lift kits that compromise on-road comfort for off-road performance, Dobinsons engineers their valve tuning to deliver compliant damping over small bumps and corrugations typical of daily driving, while still providing control during aggressive off-road use. Many Landcruiser 300 owners report that this kit actually rides better than the factory suspension, especially when the vehicle is loaded with touring gear or towing. The key is honest spring rate selection based on your actual constant load—over-spring the vehicle and you'll sacrifice ride quality unnecessarily.
