Dobinsons IMS 2 Inch Lift Kit for Toyota Landcruiser 100 Series IFS (1998-2007)

This Dobinsons IMS kit delivers approximately 2 inches (50mm) of total lift height measured from standard ride height. Actual lift achieved may vary by 5-15mm depending on your constant accessory load, selected spring rates, and whether you're running front coil replacements (not included in base kit). The kit focuses on raising the rear with Dobinsons raised coil springs, while front lift is typically achieved through coil replacement or torsion bar adjustment depending on your 100 Series variant. After the recommended 500km break-in period, springs will settle approximately 5-10mm lower than initial installation height. This 50mm lift is ideal for fitting up to 33-inch tyres with minimal trimming and provides noticeable improvements in ground clearance and off-road capability.

This kit includes four Dobinsons IMS monotube shock absorbers (two front and two rear) plus two Dobinsons raised rear coil springs with load-specific spring rates selected at checkout based on your constant accessory weight. The shocks feature 46mm bore monotube construction with high-pressure nitrogen gas charging for superior heat dissipation and fade-free performance. Please note that front coil springs, upper control arms, diff drop kits, extended brake lines, and fitting hardware are not included in this base kit and may be required depending on your vehicle's configuration and desired lift outcome. We recommend contacting our team to discuss a complete package tailored to your specific Landcruiser 100 Series build and intended use.

Yes, this IMS lift kit significantly improves towing performance by reducing rear squat and maintaining stable ride height when towing caravans or camper trailers up to 3500kg (within your vehicle's rated towing capacity). The load-rated rear coil springs provide firmer support under tongue weight, while the monotube shocks deliver consistent damping to control trailer sway and improve highway stability. However, if you frequently tow heavy loads or experience varying tow weights, we strongly recommend complementing this kit with airbag suspension for adjustable load support — airbags allow you to fine-tune rear ride height and spring rate on-demand for optimal performance whether unladen, loaded, or towing. This combination delivers the best of both worlds: excellent unladen ride quality with the capability to handle maximum loads safely.

While not strictly mandatory for a 2-inch lift on the Landcruiser 100 Series, upgraded control arms are highly recommended for optimal suspension geometry, improved CV axle angles, and enhanced off-road articulation. At 50mm of lift, your front suspension geometry changes slightly, which can affect camber and caster angles — this is easily corrected with a professional wheel alignment. However, if you plan to tackle serious off-road terrain with maximum articulation, or if you intend to fit larger tyres (33 inches and above), aftermarket upper control arms with increased offset will restore factory CV angles, reduce wear on driveline components, and provide additional wheel travel. Many Landcruiser 100 Series owners choose to install control arms at the time of lift kit fitment to maximize the investment and achieve the best possible handling both on and off-road.

Yes, a full four-wheel alignment is absolutely mandatory after installing any suspension lift kit including this Dobinsons IMS system. Raising your Landcruiser 100 Series by 50mm alters the suspension geometry and affects camber, caster, and toe angles — all of which directly impact tyre wear, steering feel, and vehicle stability. Without proper alignment, you may experience uneven or accelerated tyre wear (particularly on the inside or outside edges), steering pull to one side, and compromised handling characteristics. We recommend having the alignment performed by a specialist 4WD suspension shop familiar with lifted Landcruisers, as they can set camber and caster to optimized specifications for your intended use (touring, off-road, daily driving). Most vehicles will require adjustment to toe and camber at minimum, with caster adjustments potentially needed via aftermarket control arms.

Spring rate selection must be based solely on your constant accessory load — the weight of permanently fitted accessories your vehicle carries every day, not occasional loads or towing weight. For the front, calculate the combined weight of bull bars, winches, upgraded batteries, driving lights, and intercoolers or radiator upgrades. For the rear, include drawer systems, dual batteries, long-range fuel tanks (empty weight), canopies or hard lids, rear bars, and permanently mounted spare tyre carriers. Add up these weights separately for front and rear, then select the appropriate spring rate category at checkout (typically Light, Medium, or Heavy load ratings). Selecting a spring rate that's too heavy for your actual constant load will result in a harsh ride, excessive ride height, and potential damage to other suspension components, while choosing too light will cause sagging and reduced performance. If you're unsure, contact our team with a list of your accessories for personalized spring rate recommendations.

With the Dobinsons IMS 2-inch lift providing approximately 50mm of additional clearance, most Landcruiser 100 Series owners can comfortably fit 33-inch tyres (285/75R16 or 265/75R17) with minimal to no trimming of plastic inner guards and mudflaps. Some rubbing may occur at full lock or during extreme articulation depending on wheel offset, tyre width, and suspension compression — minor trimming of the front mudflaps typically resolves this. If you're planning to run 35-inch tyres, you'll likely need additional modifications including body lifts, significant guard trimming, aftermarket control arms, and possibly diff gearing changes to maintain drivability. We recommend test-fitting tyres at full steering lock and full suspension compression before committing to wheel and tyre purchases. The ideal setup for most touring applications is 285/75R16 tyres on 16x8 wheels with -20 to 0 offset, which provides excellent clearance without compromising CV angles or requiring extensive modifications.

This Dobinsons IMS lift kit is backed by Dobinsons' comprehensive manufacturer warranty covering defects in materials and workmanship under normal use conditions. Dobinsons shock absorbers typically carry a warranty period of 2-3 years or 60,000-100,000 kilometres (whichever occurs first), while coil springs are covered for the same period against sagging or breakage when correctly selected for your vehicle's load rating. Warranty terms require professional installation, correct spring rate selection based on actual constant load, and adherence to recommended service intervals including regular shock and spring inspections. Warranty claims are processed through Dobinsons' authorized dealer network across Australia. It's important to retain your proof of purchase and installation records, and to register your product with Dobinsons if required to activate full warranty coverage — contact us for specific warranty documentation and registration details.

Absolutely — the Dobinsons IMS monotube shock technology is specifically engineered to deliver premium on-road ride quality while providing exceptional off-road capability when needed. The large 46mm bore and increased oil capacity ensure consistent, fade-free damping during long highway journeys, absorbing expansion joints, potholes, and road imperfections with plush control. The load-matched coil springs maintain comfortable compliance when unladen for daily commuting, while progressive spring rates provide firm control under load without harshness. Many Landcruiser 100 Series owners report that the Dobinsons IMS kit actually improves highway ride quality compared to worn factory suspension, with better body control, reduced pitch and roll, and noticeably improved towing stability. This makes the kit ideal for Australian touring applications where you might cover thousands of highway kilometres to reach remote destinations, then tackle challenging off-road tracks — all with a single, well-balanced suspension setup.
