Tough Dog raised rear leaf springs for the Nissan Navara D21 and D22 (01/1986 - 2015), approximately 40mm of lift, sold per pair. Select 0-300kg for mixed use (T63, supplied as a left-hand and right-hand pack) or Constant 300kg for permanent loads (T63H).
Add U-bolts, greasable shackles and pins, urethane bushes or Air Assist bellows airbags (D22 only) from the options below.
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.

Pair with Tough Dog rear shocks.

| Nissan | Navara | D22 | 1997 - 2015 |
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 |

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 (T63-LH + T63-RH) suits daily driving with variable loads. CONSTANT 300kg (T63H) is for weight that never leaves the ute. Constant-load springs ride firm when empty.
Tough Dog offers the bellows airbag kit for the D22 only - add the 40mm-lift kit (TDAA-107) from the options to match these raised springs. No kit is listed for the D21.
These suit the following applications: Nissan Navara D21 01/1986 - 1997; Nissan Navara D22 1997 - 2015. 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.
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.
