Timing Cover Bolts

Timing Cover Bolts: the fasteners that keep your cover sealed and true

Timing cover bolts hold the front cover flat against the block so the gasket seals and the crank seal stays concentric. When the factory bolts stretch, gall, or back off, you get oil weeping at the cover, uneven clamp load, and a cover that can shift enough to chew a front seal. Fitting a fresh, matched bolt kit gets you consistent thread engagement and even clamp across the whole cover, which is exactly what you want when you have the front of the engine apart anyway.

What ThreePiece stocks

This category holds 4 products from 2 brands, ARP and Kuryakyn. Current in-stock pricing runs from $42 to $149 - that is the live range for what is on the shelf right now, not a locked-in price. ARP makes up most of the range with dedicated bolt kits, including the ARP 12pt Timing Cover Bolt Kit LS1 - LS2 at the low end and the ARP Buick 350 Timing Cover and Water Pump Hex Bolt Kit. Kuryakyn covers the top of the range with the Kuryakyn Timing Chain Cover Set for 01-17 GL1800 in chrome.

How to choose

The real decision here is bolt-kit versus cover set. If your cover is good and you just need proper fasteners, an ARP hex or 12-point kit is the straightforward buy - the 12-point head clears tight front-of-engine packaging, while the hex kit is easier to reach with a standard socket. Note that the Buick 350 kit bundles the water pump bolts too, so it covers more of the front assembly in one purchase. If you are dressing up a Honda GL1800 rather than replacing hardware alone, the Kuryakyn set is a full chrome cover kit and sits at the higher price for that reason. Match the kit to your engine by the make and part number in the listing.

Fitment

One product in this category lists specific fitment: the Kuryakyn set fits Honda GL1800 across a 2001-2017 year range. The ARP kits are called out by engine family in their product names. Confirm your engine and cover style against the exact listing before ordering, and call the number below if you are unsure which head style or thread you need.

What else you need with it

Fresh bolts belong with fresh seals, so pair them with items from Gasket Kits or the relevant Head Gaskets while the front is open. If you are further into the engine, browse Bearings, Pistons, and cooling parts like Radiators. You will find the full lineup in the Engine Components section, plus Oil Filters for the reassembly.
