Cam Bolts

Cam Bolts: the small fastener holding your cam timing together

A cam gear bolt is the fastener that clamps the cam gear or sprocket to the end of the camshaft, holding your valve timing where it was set. It sees load every time the cam is driven, so on a built or high-revving engine the factory bolt is a common upgrade point. When you swap cams, degree a gear, or open up an engine for a rebuild, replacing these cam bolts with a stronger fastener is cheap insurance against the gear slipping or the bolt backing off. Anyone who has had a cam gear move on them fits better hardware next time.

What ThreePiece stocks

This category currently lists 4 products from 2 brands: Brian Crower and ARP. Three of the four are Brian Crower parts, one is ARP. Current in-stock prices run from $27 to $68 - that is the live range for what is on the shelf now, not a fixed promise.

Fitment data is attached to 3 of the products, covering Subaru and Toyota across model years roughly 1990 to 2021. Named vehicles in that data include the Toyota Supra, Subaru WRX, Subaru WRX STI and various Subaru EJ models. The Subaru EJ AVCS long cam gear bolt is the option to check if you are running AVCS.

How to choose

Match the part to your engine first, then to the job. The Brian Crower cam gear bolts here are engine-specific - the 2JZ/1JZ bolt with washer is built for those Toyota inline sixes, and the EJ options are cut for Subaru applications, with a note on AVCS versus long variants. Buy the one listed for your exact engine and cam setup rather than by price alone. The ARP kit sits at the low end of the range near $27, the Brian Crower single bolts sit higher, into the $60s. Confirm the part matches your camshaft and gear before ordering, since these are not interchangeable across platforms.

What else you need with it

Cam bolts rarely come out alone. If the front of the engine is open, plan for head gaskets and a gasket kit to seal it back up, and check your bearings while you are in there. A rebuild that touches the cams often reaches the pistons too. Browse the full Engine Components section for the rest of the hardware.
