Our custom billet return spring bracket is included when purchasing our billet one-piece heads as part of the complete package.

A lot of our 3L guys have been asking for higher compression heads.
ATAT Performance Parts Australia can machine your existing heads to increase compression and re-machine the O-ring groove back into them.

To get this happening we need 5 more sets to commit before we start the run.
First in, first done. 🚤🔥

Calling all 3lt Merc guys and girls

The billet alternator bracket you’ve all been asking for is here.
Designed for high-performance race boat setups where strength and reliability matter.

To make this happen, the manufacturer requires a minimum run of 10 units, so we need at least 10 pre-sales before we can go ahead.

Pricing will be posted in the next few days. Keep watching this post.
