Valve Cover Bolts

Valve Cover Bolts: the small hardware that keeps your top end sealed

Valve cover bolts are the fasteners that clamp the valve cover down onto the cylinder head and squeeze the gasket so oil stays inside the engine. When they back off, corrode, or get over-torqued and stretched, you get seeping oil around the head, oil pooling in spark plug wells, and a mess down the side of the block. Fresh, evenly torqued valve cover bolts restore a clean, consistent clamp load across the sealing surface, and many owners upgrade the hardware at the same time they fit a new cover for looks and a proper reseal.

What ThreePiece stocks

This category currently holds 13 products spanning covers and related hardware, from 8 brands: Skunk2 Racing, Edelbrock, Ford Racing, Granatelli Motor Sports, ARP, Kuryakyn, Victor Reinz and HKS. Prices run from $45 to $490, which is the current range for what is in stock rather than a fixed promise. At the top end sits the Skunk2 K Series magnesium valve cover, and the range includes the Ford Racing Black Satin EFI valve covers, the HKS RB26 transistor cover in black and a chrome Kuryakyn Lightning cover for the GL1800.

How to choose

Start with what you actually need. If you only need to reseal, hardware and gasket-focused items are the low end of the price spread. If you want a dress-up or performance cover, expect to pay more, and check the mounting style. The Granatelli LS tall cover with integral angled coil mounts is sold as a pair and moves the coils, while the standard height Granatelli LS cover keeps a lower profile for tight engine bays. Lightweight magnesium and race-oriented covers cost more; a straightforward hardware refresh does not.

What else you need with it

Reusing an old gasket on a fresh clamp is false economy. Pair the job with a gasket from Gasket Kits or the matching part in Head Gaskets. While the top end is open, it is a sensible time to look at Oil Filters, and if you are chasing an oil leak elsewhere, Fittings and Adapters live in the same section. Browse the full Engine Components section for related hardware.

Fitment and ordering

Fitment data is available on some products here, with coverage samples touching makes including Ford, Hyundai, Honda and Chevrolet and years spanning 1959 to 2017. Because covers and bolts are engine-specific, confirm the part matches your head before buying. For help, call fitment support at 813-535-5801 or reach us through Contact Us. All orders ship with free shipping, and Affirm and Katapult financing is available through Financing if you want to spread the cost.
