Tough Dog rear coil springs for the Toyota LandCruiser Prado 250 Series (2024-on), sold per pair with 50mm of lift, rated to the load you carry. Height-matched coil insert airbag kits and the required TDSP-028 rear sway bar bracket can be added below. Constant-500kg springs need the FC43064 shock valving.
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 |
|---|---|---|---|
| TDC1138 | 50 mm | 0-300 kg | - |
| TDC1139 | 50 mm | Constant 300 kg | - |
| TDC1140 | 50 mm | Constant 500 kg | - |
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.
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.
On Kakadu and VX models, yes - the OEM Adaptive Variable Suspension function is lost when the front and rear shocks are replaced with Tough Dog suspension.
The TDSP-028 rear sway bar bracket must be fitted with every lift kit - add it on the rear coil springs. New strut tops (2x TOY-4942, $120 ea) are available - contact us. Replacement bush kits (TDUK-057 front, TDUK-058 rear, TDUK-032 panhard) and UCA service kits (TDSK-015/016) are also available.
If you are changing ride height, yes. Shocks are built for a specific travel range, and a lift moves the axle outside the factory shock's range. If you are replacing springs at standard height, existing shocks in good condition can stay.
These Tough Dog springs are listed for the Toyota Prado 250 Series. Check the fitment table above against your build date and body style, or send us your rego and we will confirm the right part.
