Tough Dog raised rear coil springs for the Mitsubishi Pajero Sport QE/QF (2015 onwards), approximately 20mm of lift, sold per pair. Select 0-300kg for mixed use (TDC638L) or Constant 300kg for permanent loads (TDC638HL).
Carrying weight often? Add the Tough Dog coil-insert Air Assist airbag kit from the options below.
These are Australian-designed and manufactured springs in micro-alloyed spring steel. Each coil is shot-peened, scragged and load-tested before it leaves the factory, and the hot-forming process is what lets them hold their free height under sustained load.
Pick the rate for the weight the vehicle actually carries, not the weight you'd like it to carry – and count only permanent accessories and loads (bar, winch, drawers, long-range tank) when choosing. A spring that's too firm for an unloaded vehicle rides worse than the factory item; one that's too soft sags the moment you load up.
Fit springs in pairs per axle, and book a wheel alignment after any change in ride height. It's also worth checking brake-line slack and bump-stop condition while the suspension is apart.
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 |

| TDC638HL | 20 mm | Constant 300 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.
0-300kg (TDC638L) suits daily driving with variable loads. CONSTANT 300kg (TDC638HL) is for weight that never leaves the vehicle. Tough Dog warns that using a Constant Load spring without the load fitted will result in tailshaft vibration.
These suit the following applications: Mitsubishi Pajero Sport QE, QF 2015 - 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.
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.
