Tough Dog rear coil springs for the Toyota LandCruiser Prado 150 Series (2010-on), sold per pair. The same spring sits differently on SWB and LWB bodies - the labels show both. Height-matched coil insert airbag kits are available below. Kakadu models need the airbag-to-coil conversion springs.
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.

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.
| Part number | Lift | Load rating | Suits / notes |
|---|---|---|---|
| TDC975S | 40 mm | 0-300 kg | SWB: OE |
| TDC975 | 40 mm | 300 kg | SWB |
| TDC975H | 40 mm | Constant 300 kg | LWB |
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. Raised springs need shock absorbers with the correct extended length for the new ride height. 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.
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.
Pick the rating for the weight the vehicle carries most of the time, counting only permanent fitments. Options on this listing: 0-300 kg, 300 kg, Constant 300 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 electronically controlled dampers on the 150 Series can be replaced with Tough Dog shocks without error indicators appearing, but all FOUR shock absorbers must be replaced at the same time. If operating correctly, the electronically-adjustable height control of factory rear airbags is not affected.
Yes - use the TDC1095 / TDC1096 conversion springs. The electronic workaround in the supplied instructions prevents error indicators, but it disables the electronic dampening system, so all four electronic dampers must be replaced with Tough Dog shocks at the same time. You also need the genuine Toyota bump-stop coil retainer, part 48302-60110 or 48302-60080. New strut tops (2x TOY-1083) and an 83mm sway bar spacer (TDSP-012, $75) are also available - contact us.
The options on this listing are: 40 mm. Lift is measured at ride height with the vehicle's normal load. Raised springs need matching shock absorbers with the correct extended length.
Yes. The price covers both Tough Dog springs, one for each side.
