Dobinsons Monotube IMS 2" Lift Kit — Toyota Landcruiser 300 Series

This Dobinsons kit provides approximately 50mm (2 inches) of lift at both the front and rear, measured from factory ride height with standard load. Actual lift height may vary slightly depending on your chosen spring rate and constant accessory load — heavier front-end accessories like steel bull bars may reduce front lift by 10-15mm. Regarding warranty, reputable lift kit installation should not void your Toyota factory warranty under Australian Consumer Law, provided the suspension modification is not proven to be the direct cause of any mechanical failure. We recommend keeping all receipts and having installation performed by a qualified workshop to maintain documentation, and always inform your insurer of any suspension modifications.

This complete Dobinsons kit includes 2 x IMS adjustable front struts with preload adjustment, 2 x front coil springs (load-rated to your selection), 2 x IMS monotube rear shock absorbers, and 2 x raised rear coil springs (load-rated to your selection). All components are engineered specifically for the LC300 platform and include necessary hardware for installation. Please note that this kit does NOT include upper control arms, extended brake lines, diff drop brackets, or wheel spacers — these may be required depending on your intended tyre size and should be purchased separately. Contact us if you need a complete package recommendation for your specific build requirements.

Absolutely — this Dobinsons Monotube IMS kit is specifically engineered to handle the LC300's 3,500kg towing capacity and substantial payload demands. The load-rated coil spring options allow you to select appropriate spring rates for your constant accessory load, while the monotube shock design delivers superior damping control under heavy loads and during extended towing sessions. For maximum towing performance and rear-end support when towing at or near maximum capacity, many customers pair this lift kit with airbag suspension for on-demand load levelling. The IMS shocks maintain consistent damping performance even with caravan sway and corrugated tracks, making this an excellent choice for serious tourers and grey nomads.

While not strictly mandatory for a 2" lift, upgrading to aftermarket upper control arms is highly recommended for the LC300 when installing any lift kit. Aftermarket control arms correct the castor angle and restore factory geometry, which improves steering feel, reduces tyre scrub, and maintains proper suspension travel and wheel alignment. Without corrected castor, you may experience wandering steering, increased tyre wear, and reduced self-centering at highway speeds. Many experienced LC300 owners install upgraded control arms at the same time as their lift kit to maximise the benefits and avoid needing to return to the workshop later — contact us for specific control arm recommendations compatible with this Dobinsons kit.

Yes, a full four-wheel alignment is absolutely mandatory after installing any lift kit, including this Dobinsons system. Lifting your LC300 alters suspension geometry, camber, castor and toe angles, which can cause premature and uneven tyre wear, poor handling, and steering issues if not corrected. Your alignment technician should set your vehicle to the adjusted specifications appropriate for a lifted LC300, not factory specifications. We recommend finding a suspension specialist or 4WD alignment shop experienced with lifted Landcruisers rather than a standard tyre shop. Also allow for a 500km settling period, then recheck alignment as springs and bushings bed in — some minor ride height drop is normal during this break-in phase.

Yes — one of the key advantages of this Dobinsons kit is the ability to select custom spring rates for both front and rear based on your specific constant accessory load. When ordering, you'll be asked to select front and rear spring rates separately. Choose based only on permanently fitted accessories such as bull bars, winches, drawer systems, long-range tanks, and roof racks — NOT occasional loads like camping gear or towing weight. Selecting the correct spring rate is critical for ride quality, handling and component longevity. If you over-spring your vehicle by choosing rates that are too heavy, you'll experience harsh ride quality, reduced articulation, and potential damage to other suspension components. Contact our team if you need help calculating your constant load and selecting appropriate spring rates.

With this Dobinsons 2" lift kit installed, most LC300 owners can comfortably fit 285/70R18 tyres (approximately 33 inches) with minimal to no rubbing, depending on wheel offset and driving conditions. Some light trimming of plastic inner guards may be required for full articulation off-road. For 285/75R18 or larger tyres, you'll likely need additional modifications such as guard trimming, body mount chop, diff drop, or aftermarket upper control arms to achieve full clearance at lock and under compression. Your final tyre clearance also depends on wheel offset — more negative offset pushes tyres outward and increases scrub radius. We recommend test-fitting your intended tyre and wheel combination and checking clearance through full steering lock and suspension compression before committing to cutting factory components.

Dobinsons backs this Monotube IMS Lift Kit with a comprehensive manufacturer's warranty covering defects in materials and workmanship. Specific warranty terms vary by component — shock absorbers and struts typically carry a 2-year warranty, while coil springs are covered for the life of the product against sagging or breakage under normal use. Warranty coverage requires proof of purchase and is subject to proper installation by a qualified technician, regular maintenance, and use within the product's designed parameters. Warranty does not cover damage from accidents, misuse, modification, or installation errors. For full warranty terms and conditions or to register your product, visit the Dobinsons website or contact us directly — all warranty claims are handled promptly through our Australian distributor network.

Yes — unlike budget lift kits that compromise on-road comfort for off-road capability, the Dobinsons Monotube IMS system is engineered to deliver excellent ride quality for daily commuting and highway touring while still providing controlled performance on challenging 4WD tracks. The monotube shock design offers superior damping consistency and heat dissipation compared to twin-tube alternatives, maintaining comfortable highway manners even after extended corrugated road driving. The adjustable front struts allow fine-tuning to suit your load and driving style, while the load-rated coil springs prevent the harsh, over-sprung ride common with incorrectly specced lift kits. Many LC300 owners report that this Dobinsons kit actually improves ride quality over worn factory suspension, particularly when carrying typical touring loads and accessories.
