Tough Dog rear coil springs for the Toyota LandCruiser 80 Series (05/1990-1998) and 105 Series (03/1998-2007), sold per pair. Pick your lift height first, then the spring for your build era and constant load. Coil insert airbag kits are available on the 25mm and 50mm springs below.
These are Australian-designed and manufactured springs in micro-alloyed spring steel. Each coil is shot-peened, scragged and load-tested before it leaves the factory, and the hot-forming process is what lets them hold their free height under sustained load.
Pick the rate for the weight the vehicle actually carries, not the weight you'd like it to carry – and count only permanent accessories and loads (bar, winch, drawers, long-range tank) when choosing. A spring that's too firm for an unloaded vehicle rides worse than the factory item; one that's too soft sags the moment you load up.
Fit springs in pairs per axle, and book a wheel alignment after any change in ride height. It's also worth checking brake-line slack and bump-stop condition while the suspension is apart.
Doing the whole vehicle at once? We also stock the matching adjustable Rear Panhard Rod and front Shock Absorbers for the Toyota LandCruiser 80 & 105.
Match them with Tough Dog rear shocks.

Choose the load rating for the weight the vehicle carries most of the time, counting only permanent fitments such as a bar, winch, canopy or drawers. A heavier rating than you need rides firm when unloaded; a lighter one sags once the gear goes in.

Rear coil springs are changed with the axle supported and the lower shock mount unbolted so the axle can drop far enough to slip the old spring out. Check brake hoses, ABS leads and the breather have enough slack at full droop, especially with raised springs, and fit both sides together. In most states a suspension lift of up to 50 mm is allowed without certification under VSB14; larger lifts can require engineering approval, so check the rules for your state.

Load ratings refer to permanent extra weight over the axle. Springs do not change the vehicle's GVM or towing capacity.
These suit the following applications: Toyota LandCruiser 80 Series 05/1990 - 1998; Toyota LandCruiser 105 Series 03/1998 - 2007. Check your build date and variant against the fitment table on this page – if you're not certain, contact us with your rego or VIN details and we'll confirm fitment before you order.
The listed price covers both sides – always replace left and right together so the axle is evenly damped and sprung. It's a bolt-in job for a competent home mechanic or any workshop; check bushes, mounts and brake-line slack while everything is apart.
Yes - 75mm and taller lifts need an extended rear brake hose kit: TDBH-003 rubber / TDBH-197 braided (80 & 105 non-ABS), TDBH-300 rubber / TDBH-200 braided (80 Series ABS), TDBH-398 rubber / TDBH-198 braided (105 Series ABS). Contact us to add the right kit to your order.
A moderate suspension lift is generally acceptable in most Australian states, but the allowed total lift and whether certification is needed differ between states and change over time – so always confirm with your state’s transport authority before modifying. Our guide explains how the rules work state by state: are lift kits legal in Australia?
Pick the rating for the weight the vehicle carries most of the time, counting only permanent fitments. Options on this listing: 0-300 kg, Constant 300 kg, Constant 500 kg. A '0-300 kg' or light rating suits a mostly unloaded vehicle; 'Constant' ratings suit a vehicle that always carries that weight, such as a canopy, drawers and a fridge.
Yes. The price covers both Tough Dog springs, one for each side.
