Built Tough. Runs Cooler. Looks Better.

Every 1KD owner knows the story. The day you spot oil pooling around the injectors or running down the back of the head. The factory plastic cover cracks or warps, and suddenly your clean, reliable diesel looks tired. It's frustrating, it's messy, and it happens to almost everyone running a 1KD long enough.

That's why over 715 Aussie Hilux and Prado owners have already made the switch to the Common Rail Cowboys cast aluminium rocker cover. No more leaks. No more warping. Just a solid, engineered piece of gear that looks as good as it performs.

This is the real fix, not a patch job. Machined from heavy-duty cast aluminium, built for Australian heat and hard driving, and finished in a clean silver coat that transforms your engine bay. You'll open the bonnet and smile every time.

Frequently Asked Questions

Why is the factory plastic rocker cover such a problem on 1KDs?
The 1KD runs hot, and the factory plastic cover wasn't built to last. After years of heat cycling it becomes brittle, warps around the bolt holes, and starts weeping oil down the back of the head where it pools around the injectors. The plastic doesn't recover once it's warped, so no amount of retorquing or gasket replacement fixes it for long. Cast aluminium doesn't warp. Full stop.

Can I just replace the gasket and reuse my plastic cover?
You can, but if your cover has been leaking for a while, the plastic around the bolt holes is likely already deformed. A new gasket might buy you a few months, but it'll leak again. If you're pulling the cover off anyway, it's the perfect time to upgrade and never deal with it again.

How hard is it to fit?
Straightforward job for anyone with basic mechanical ability. It mounts to the same bolt pattern as the factory cover, no modifications, no drilling. The main thing to remember is don't torque the bolts, tighten by feel only.

Does it come with all the seals I need?
Yes, the kit includes the rocker cover gasket and injector seals to get it fitted straight away. If you want genuine Toyota seals rather than aftermarket, add the genuine fitting kit using the buttons above.

Will it suit my setup if I'm running a tune or towing heavy?
Absolutely. Aluminium handles heat better than plastic, so it's actually more at home on a worked 1KD than the factory cover ever was. Plenty of our customers run tunes, lift kits and big tow setups without issue.

Will it fit both Hilux and Prado?
Yes, it fits any non-DPF 1KD-FTV. That covers Hilux N70 (2005 to 2015) and Prado (2003 to 2015). Pre-2015 1KDs are almost always non-DPF. If you're unsure, send us a message with your VIN.
