This complete Tough Dog suspension kit for the Toyota LandCruiser 100 Series IFS (1998 - 2007) lifts the vehicle approximately 25mm front and rear. Heavy duty torsion bars lift and firm up the independent front end, with raised rear coils and matched shocks to level the vehicle. Every part in the kit is a Tough Dog component selected for this vehicle, and the dropdowns let you set the shock type and spring rates to suit how the vehicle is used.

The base kit is supplied with Foam Cell Front & Rear shocks; you can step up to Foam Cell Front/40mm Bore Adjustable Rear (+ $60.00), Big Bore Ralph Front & Rear (+ $400.00), Big Bore Ralph Front/45mm Bore Adjustable Rear (+ $420.00) from the dropdown. Choose rear springs in 0-300kg Load / Constant 300kg Load to match the gear your vehicle carries permanently.
| Option | Choices |
|---|---|
| Engine Type | Petrol / Diesel |
| Shock Configuration | Foam Cell Front & Rear / Foam Cell Front/40mm Bore Adjustable Rear (+ $60.00) / Big Bore Ralph Front & Rear (+ $400.00) / Big Bore Ralph Front/45mm Bore Adjustable Rear (+ $420.00) |
| Rear Spring Rate | 0-300kg Load / Constant 300kg Load (+ $94.00) |
Rate the springs to the weight the vehicle carries all the time: a steel bull bar, winch, canopy, drawers, long-range tank or service body. Camping gear, a trailer or an occasional load do not count. Going too heavy on the springs gives a harsh unladen ride and less wheel travel, so if the vehicle is between ratings, pick the lighter one and talk to us if you are unsure.
Bolt-in fitment with no cutting or welding. A wheel alignment is required after fitting. A lift of this size is within the limits most states allow without engineering, but check your local rules.

Suits the independent front suspension Toyota LandCruiser 100 Series (1998 - 2007). Select petrol or diesel when ordering as torsion bar rates differ. The solid-axle 105 Series uses our 105 kits.
The complete kit is $1,696 with the standard options; shock upgrades and heavier spring rates add the amounts shown in the dropdowns, and we ship Australia-wide. Tough Dog parts carry the manufacturer's Australian warranty, and a 25mm lift within your state's limits does not void your new-vehicle warranty on its own.

The kit for the Toyota LandCruiser 100 Series IFS (1998 - 2007) contains 2 x Front shock absorbers, 2 x Heavy duty front torsion bars, 2 x Rear coil springs, 2 x Rear shock absorbers, 1 x Front HD torsion bars, 1 x Front control arm reinforcement bracket. Everything is a Tough Dog part selected for this vehicle, so there is nothing else to buy for a standard 25mm lift. Optional upgrades (shock type, spring rates) are chosen from the dropdowns above.
Approximately 25mm front and rear on the Toyota LandCruiser 100 Series IFS with the standard spring rates. Heavier spring rates sit a little higher unladen and settle under a bull bar, canopy or constant load; the final height also varies with tyre size and the condition of the vehicle, and settles after the first few hundred kilometres.
The complete 25mm kit for the Toyota LandCruiser 100 Series IFS is $1,696 with the standard options; a shock upgrade and heavier spring rates add the amounts shown in the dropdowns. That price covers every part listed above, so there is nothing else to buy for a standard lift, and we ship Australia-wide.
A 25mm suspension lift is within the limit most Australian states allow on a Toyota LandCruiser 100 Series IFS without engineering approval. Some states count a tyre size increase toward the total lift, so if you are also going up a tyre size check your state's light vehicle modification rules. Keep the lift to this kit's rating and have the wheel alignment done and it stays a road-legal, insurable modification.
Choose rear springs in 0-300kg Load / Constant 300kg Load to match what the LandCruiser carries permanently: a steel bull bar and winch on the front, a canopy, drawers, tray or long-range tank on the rear. Only count gear that stays on the vehicle; camping loads and a trailer do not. Towing a caravan or heavy trailer regularly justifies the next rear rate up. If you are between ratings, take the lighter one for a better unladen ride, or call us with your setup.
Foam Cell Front & Rear shocks are the base kit and suit most daily-driven and touring vehicles. Step up to Foam Cell Front/40mm Bore Adjustable Rear (+$60), Big Bore Ralph Front & Rear (+$400), Big Bore Ralph Front/45mm Bore Adjustable Rear (+$420) if the vehicle does long corrugated roads, tows or carries a constant load: Foam Cell shocks resist fade on corrugations and the adjustable options let you dial the damping up for a load and back down for empty running. Ralph is Tough Dog's 45mm big-bore shock range, built for heavy vehicles and long remote trips.
A workshop takes around 5 to 6 hours, including winding the torsion bars up to height to fit this kit to a Toyota LandCruiser 100 Series IFS, plus the wheel alignment. It is a bolt-in job with no cutting or welding, so a competent home mechanic with a hoist or solid stands, a torque wrench and basic hand tools and a torsion bar unwinding tool can do it. Follow the torque settings in the Tough Dog fitting instructions and book the alignment straight after, or have your local 4WD suspension workshop fit it.
Fitting aftermarket suspension does not void a new-vehicle warranty on its own: under Australian Consumer Law the manufacturer must show that the part caused a specific fault before refusing a claim on that item, and the rest of the warranty is unaffected. Keep the lift within the legal limit for your state, have it fitted and aligned properly, and tell your insurer about the modification so the kit is covered. Tough Dog components are backed by the manufacturer's Australian warranty; ask us for the current terms.
