Do you want peace of mind and reliability for your FA or FB engine? 

Every FA20 needs these!

Are you sick of your 86, BRZ or FR-S engine blowing up? 

We are!

It took three blown engines before realising it wasn’t a coincidence.

We have discovered that the FA & FB engines have a flaw in the valve rocker design. The rocker arm can separate from the valve assembly after a valve sticks or bounces. Once this occurs the separated rocker arm becomes a projectile inside the engine. 

As soon as the rocker finds a camshaft lobe there is a seriously high chance (note, almost certain) that it will be blown through the engine. So we created a fix by retaining the rocker arms with a clip.

This is a MUST for any Toyota 86 or any Subaru with a third-gen FA or FB engine.

We have worked with an engine performance machine shop with 25 years+ of experience manufacturing valvetrain gear to develop bespoke drop-in pivots that will outperform the OEM ones.

Q1. What is the estimated shipping time from Australia to USA?

Q2: If I modify my camshafts will your rocker retainers still work?

A2: Yes. As there would be no change to the rockers, our clip and pivot will still work.
