Tough Dog 50mm raised rear leaf springs for the Toyota LandCruiser 76 Series (2007 onwards), sold per pair. Pick the spring rated for your constant load, then add the fitment hardware below - the shackle bush kit differs before and after 01/2017, and pre-01/2017 vehicles must fit the TDSP-014 brake bias bracket.
These are progressive-rate packs – every leaf sits in contact along its full length with the leaf above, which is what keeps the unladen ride tolerable on a working ute.
Two-stage packs carry a lighter primary stage for everyday ride quality, with heavier second-stage leaves that only come into play as the load goes on – that's what stops the rear sagging with a canopy, tools or a camper on the back. Choose the rating by the constant load the vehicle carries, counting only permanent weight.
The matching U-bolts, greasable shackles and pins, and bush kits are available from the option dropdowns on this page – if the originals have been on since new, replace them while the pack is out rather than reusing stretched U-bolts.
Doing the whole vehicle at once? We also stock the matching front Coil Springs and front Shock Absorbers for the Toyota LandCruiser 76 Series.
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 |
|---|---|---|---|
| FS761 | 50 mm | 0-300 kg | - |
| FS761M | 50 mm | Constant 300 kg | - |
| FS761HM | 50 mm | Constant 500 kg | - |
Leaf springs are replaced as a pair with the axle supported, the U-bolts removed and the spring unbolted from the front hanger and rear shackle. Fit new U-bolts, and replace worn shackle bushes and pins at the same time. Torque U-bolts to spec and re-check them after the first few hundred kilometres. 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.
These suit the following applications: Toyota LandCruiser 76 Series (4.5L V8, 4.2L 6cyl, 2.8L 4cyl) 2007 - On. 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.
Pre-01/2017 vehicles use TDUK-048 (with the TDGS-387/18 shackle and TDGP-388 pins). Post-01/2017 vehicles reusing their OEM pins and shackle use TDUK-048/14. Pick the matching add-on below.
Yes if you run the BMX 45mm Adjustable or Ralph TDR rear shocks - the TDSP-015 handbrake relocation bracket must be fitted with those shocks.
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, 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.
The options on this listing are: 50 mm. Lift is measured at ride height with the vehicle's normal load. Raised springs need matching shock absorbers with the correct extended length.
