Tough Dog raised rear leaf springs for the leaf-rear Nissan Patrol GQ and GU cab chassis (1988 - 2016), approximately 50mm of lift, sold per pair. Select 0-300kg for mixed use, or Constant 300kg / 500kg / GVM mine-spec for permanently loaded utes.
Add U-bolts, greasable shackles and pins, urethane bushes or Air Assist bellows airbags from the options 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.

Pair 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 |
|---|---|---|---|
| BPN-010 | 50 mm | 0-300 kg | - |
| BPN-010H | 50 mm | Constant 300 kg | - |
| FS39M-LH/RH | 50 mm | Constant 500 kg | - |
| FS38M-LH/RH | 50 mm | - | Constant GVM Mine Spec |
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.
0-300kg (BPN-010) suits daily driving with variable loads. CONSTANT 300kg (BPN-010H), CONSTANT 500kg (FS39M) and the CONSTANT GVM mine-spec pack (FS38M) are for weight that never leaves the ute - they ride firm when empty.
These suit the following applications: Nissan Patrol GQ/GU Cab Chassis - Leaf Rear 02/1988 - 1997; Nissan Patrol GU Cab Chassis - Coil Front, Leaf Rear 1997 - 2016. 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.
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.
