Tough Dog raised front coil springs for the Isuzu D-MAX RG (August 2020 on), approximately 40mm of lift, sold per pair. Choose No Accessories (TDC974) for a stock front end or Bar / Winch (TDC974H) when running a steel bull bar or bar and winch.
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.
Doing the whole vehicle at once? We also stock the matching assembled Front Struts and front Struts for the Isuzu D-MAX RG & Mazda BT-50 TF 2020-On.

Genuine Tough Dog suspension from an authorised Australian dealer.
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 2020-on Mazda BT-50 TF is built on the Isuzu D-MAX RG platform and Tough Dog specifies identical part numbers for both. This listing covers the D-MAX RG (excluding Blade) and the BT-50 TF 08/2020 onwards.
