Tough Dog 50mm raised front leaf springs for the Toyota LandCruiser 45 Series (30mm eyes) and 47 Series (35mm eyes), sold per pair. Pick your series and the rating for your accessories, then add U-bolts, greasable shackle & pins and the shackle bush kit below.
Tough Dog leaf springs are a genuinely progressive design: each leaf is set slightly proud of the one above it, so the leaves stay in contact along their whole length instead of slapping together under load.
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 rear Shock Absorbers and rear Leaf Springs for the Toyota LandCruiser 45/47 Series.
Match them with Tough Dog front shocks.

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. 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.
Choose the spring that matches what is permanently fitted to the vehicle, such as a steel bull bar or a bar and winch. The heavier option carries that extra weight at the intended ride height; fitted to a vehicle without the accessories it will sit high and ride firm.

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 45, 47 Series 01/1965 - 1984. 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.
45 Series springs use 30mm eyes, 47 Series springs use 35mm eyes - pick the option for your series. The fitment add-ons below match the spring you choose.
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.
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?
Yes. The price covers both Tough Dog springs, one for each side.
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.
