Most of our Isuzu range is for the D-Max and MU-X: engine parts and injectors for the 3.0 litre 4JJ1 and 4JJ3, Manta exhausts, and suspension from Tough Dog, EFS and West Coast Suspensions. There are also parts for older Isuzu engines and leaf springs for N and F Series trucks. Start with the D-Max or MU-X page.

4JJ1 or 4JJ3
The 3.0 litre 4JJ1 runs in earlier D-Max and MU-X models and the 4JJ3 in later ones. Injectors, gaskets and timing parts are listed against the engine code, and within the 4JJ1 the DPF and non-DPF engines take different injectors. The engine code and build date decide it, so read both, then go to 4JJ1 parts or 4JJ3 parts.
Parts shared with Holden and Mazda
The D-Max shares a good deal with the Holden Colorado and Rodeo of the same era, and the D-Max from late 2020 shares many suspension parts with the BT-50 of the same years. Plenty of listings name all of them in the title. If yours is not named, search by engine code or send us the VIN. Holden-badged versions are on the Holden Colorado page.
Suspension and exhaust for working utes
For a ute that carries weight, the suspension here is rated to the load, from Tough Dog and EFS kits to West Coast Suspensions leaf packs. Manta exhausts are listed by engine and build date, with DPF-back systems for the DPF engines. We fit and align suspension and fit exhausts at Oxley and Warana.
Isuzu parts FAQs
Do D-Max parts fit the MU-X?
Many engine parts do, because both run the same 4JJ1 or 4JJ3. Suspension and exhaust parts usually do not, as the MU-X is a wagon with a different rear end and body. Check that the vehicle you drive is named in each listing.
How quickly do Isuzu parts ship?
It depends on the part. Where the product page says Order before 11am AEST for same-day dispatch, an in-stock part ordered by then on a business day goes out that day, and that covers the Manta exhausts. Suspension and most other parts are dispatched by the supplier, usually within 1 to 2 business days.
Do you list DPF and non-DPF injectors for the 4JJ1?
Yes, and they are not interchangeable. The Denso injector for the late DPF 4JJ1 D-Max from 2016 to 2020 is $765.00. Check whether your engine has a DPF before you order.
