ALPHA PROJECT IMPORTS Denstoj Rocker Retainers for FA/FB Subaru Engine [BUSINESS]

You should not build a Subaru FA/FB engine without these parts. Rev your engine with confidence!

Subaru FA/FB engines (e.g., the FA20 engine in the Toyota 86) have a fatal flaw. When valve spring pressure drops, the rocker arm assembly can detach. If it gets caught in the camshaft, it can fly out of the tappet cover, causing oil to leak into the exhaust manifold and creating a fire hazard.

Without the rocker arm, the valve can drop into the cylinder, potentially damaging the piston. While over-revving can be a cause, this can also happen across the entire rev range in daily driven cars.

If you own a Toyota 86 or a Subaru with an FA/FB engine, replacing this part is the most crucial upgrade to avoid an expensive engine overhaul. Drive with peace of mind.

The 2022 GR86 also has a similar issue, and even with recalled springs, this problem has not been resolved.

Why choose our rocker retainer kit?

An engine overhaul can cost thousands of dollars, and depending on the extent of the damage, it can be anywhere from $5,000 to $10,000. Parts like pistons, valves, and gaskets alone can quickly add up. Our rocker retainer kit costs a fraction of that and provides peace of mind by preventing a critical failure that could lead to an expensive overhaul.

Protect your valuable investment and drive with the confidence that your engine is safely protected.

Prices are set in Australian dollars and will automatically convert to your local currency, so there may be slight daily fluctuations.

If you are not satisfied with your purchase, we offer refunds within 30 days of receiving your rocker retainers.
