Cam Bolt Kits

Cam Bolt Kits: the fasteners that keep your cam gears locked down

A cam bolt is what clamps the camshaft sprocket or gear to the end of the cam, and on variable valve timing engines it also secures the phaser or AVCS unit. When you swap cams, degree a timing setup, or rebuild a top end, replacing these bolts with a proper kit matters because the original fasteners are torque-to-yield in a lot of applications and are not meant to be reused. A cam bolt kit gives you fresh, correctly specced hardware so the cam timing stays where you set it. Get this wrong and you can lose timing under load or spin a gear, so these are cheap insurance on an expensive engine.

What ThreePiece stocks

We currently carry 8 cam bolt kits from 3 brands: Torque Solution, ARP and Ford Racing. Prices run from $23 to $99, which is the current range for what is in stock, not a fixed price. Torque Solution makes up most of the sample with 5 kits, ARP has 2, and Ford Racing has 1.

Real examples: the ARP Cam Bolt Kit for the Ford Coyote 5.0L V8 sits at the top of the range near $99, while the ARP Ford Cam Bolt Kit 254-1001 is the budget end near $23. On the Subaru side we stock the Torque Solution HD Cam Bolt Kit for 08-20 STI EJ25 Dual AVCS and the Torque Solution HD Kit for Subaru EJ Single AVCS. There is also the Ford Racing 4.6L 3V Camshaft Bolt. Fitment data here points at Subaru, specifically the Subaru STI across 2008-2020, and the product names cover Subaru and Ford engines.

How to choose

The first question is your engine and VVT setup. Subaru EJ owners need to match single-AVCS versus dual-AVCS hardware, and the two Torque Solution kits above are split exactly on that line, so read the AVCS callout in the product name before you buy. Ford owners split by application: a full ARP kit like the Coyote 5.0L set is a heavier spend, while the single Ford Racing 4.6L 3V bolt and the entry ARP Ford kit cover different platforms at a much lower cost. In short: buy for the exact engine and timing arrangement, not just the make, and confirm whether you need a single bolt or a full kit.

What else you need with it

Cam bolts are one line on a top-end job. If you are in that deep, look at head gaskets and full gasket kits, plus bearings and pistons if the rebuild goes further. Browse the whole Engine Components section for the supporting hardware around your build.
