Don’t build a Subaru FA or FB engine without these. Rev with peace of mind!

Fits both the old and current model BRZ and 86.

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.

Included:

16x Denstoj Bespoke Drop-in Pivots
16x Denstoj Bespoke Pivot Spring Retainers.

Fitment:

Engine: All third generation Subaru FA and FB (eg. FA20, FA24, FB20, FB25)
- Note: The Subaru FA20 is also known as Toyota 4U-GSE in the Toyota 86
