No More Chasing Rusty Tin
You've spent the time and money getting your engine bay looking sharp, and then there it sits, a cheap, generic plastic reservoir killing the whole look. And the original tin unit isn't much better. Decades on, finding one that isn't pitted, split or leaking is next to impossible, and the ones that look good on the outside are often rotten within.
We got sick of it, so we fixed it for good. This reservoir was fully reverse-engineered from an original tin unit, redrawn from scratch in CAD to capture every original dimension and thread detail, then CNC machined from a solid 6061 aluminium billet and finished in Type II hard anodising. The result is a reservoir that screws straight on as a factory replacement, looks the part in a sleek engine bay and will never rust again.
Choose Your Base Thread
This reservoir is machined to the exact size and dimensions of the original EJ, EH and HD tin reservoir. Over time, Holden changed the reservoir's main base thread, Early cars used what we call the "tin thread", later cars moved to the "plastic thread" — and we have both versions.
Because we offer the plastic thread option, this reservoir isn't limited to EJ, EH and HD — the same size and dimensions make it a fit for FE, FC, FB, EK and HR Holdens as well, and later model clutch master cylinders too. Select the thread type that matches what's currently fitted to your car.
- Tin thread — matches the original early-style tin master cylinders
- Plastic thread — matches the later-style master cylinders
Choose Your Cap
Available with 2 cap options to suit your build:
- Original-style tin cap — for a factory-correct look
- Stainless steel cap — a modern, corrosion-proof upgrade
Note: either selection of cap will be fitted with a modern, sealing, cascading type rubber seal
