Tough Dog assembled front struts for the Isuzu D-MAX RT (MY12, May 2012 - August 2020), delivering approximately 40mm of front lift. Each strut arrives complete - strut, coil spring and strut top - so it bolts straight in with no spring compressor. Sold as a pair. Choose Foam Cell or 9-position 40mm Adjustable struts, with coil rates for alloy bar, steel bar, or steel bar and winch (petrol and diesel).
Assembled struts take the spring-compressor work out of a front-end upgrade on the Isuzu D-MAX RT 2012-2020: each unit arrives with the strut, coil and top already assembled and torqued, so it unbolts and bolts back in as a complete assembly.
Select the coil option that matches what the vehicle permanently carries up front – a bare bonnet, a steel bar, or bar plus winch – so the finished height lands where it should. Count only permanent accessories when choosing.
Fit them as a pair and book a wheel alignment straight after – any strut change on an independent front end moves camber and castor enough to matter for tyre wear.
Doing the whole vehicle at once? We also stock the matching front Coil Springs and rear Shocks for the Isuzu D-MAX RT 2012-2020.
Prefer to re-use your coils? See the bare Tough Dog struts.
Select for permanently fitted front-end weight: no bar or alloy bar → Alloy Bar option; steel bull bar → Steel Bar; steel bar plus winch → Steel Bar and Winch. Contact us if unsure.

Genuine Tough Dog suspension from an authorised Australian dealer.
New to D-MAX and MU-X suspension? Read our D-MAX and MU-X suspension problems guide.
The D-MAX RT shares its front end with the Isuzu MU-X (2014 - 2021), and the same Tough Dog front parts apply to many MU-X models. Send us your rego and we will confirm the exact fit before dispatch.
The listed price covers both sides – always replace left and right together so the axle is evenly damped and sprung. Book a wheel alignment straight after fitting: any change to the front end moves camber and castor enough to affect steering and tyre wear.
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?
