Nakonic Valve Cover Bolts for Chevy & GM LS Engines — 8-Pack with Washers, Heat-Resistant Finish

Nakonic 8 PCS Valve Cover Bolts are a direct-fit hardware kit engineered to replace worn or missing valve cover bolts on Chevrolet and GM LS-series engines from 1997–2014.

These bolts are intended for use on a broad range of LS-family engines—covering common V8s such as LS1, LS2, LS3, LS6, LS7 and many truck Vortec variants—so you can restore proper clamping force and help prevent oil leaks from the valve cover. The kit contains eight bolts and matching washers designed to withstand heat, oil exposure, and vibration typical of high-mileage engines. Before ordering, verify the cover bolt pattern on your vehicle: this kit will not fit early LS engines that use a perimeter-style valve cover (notably some 1997–1998 Corvettes, Camaros, and Trans Ams).

What engines and model years do these bolts fit?

These Nakonic valve cover bolts are compatible with most Chevrolet and GM LS-series engines produced between 1997 and 2014. They suit many Vortec truck engines and popular LS variants found in passenger cars and trucks.

• Compatible with LS1, LS2, LS3, LS6, LS7, LS9 and common truck blocks.
• Works with GM 4.8L, 5.3L, 5.7L, 6.0L, 6.2L engine families.
• Fits LSX, LM7, LR4, LQ4, LQ9, L33, LH6 and many L-series codes.
• Not for early perimeter-bolt valve covers (1997–1998 LS1 Corvette/Camaro/Trans Am).

How do these bolts protect my valve cover and gasket?

The kit includes washers that help spread clamping force evenly across the valve cover surface, reducing the risk of warped covers or crushed gaskets. Bolts are finished to resist oil and heat degradation, maintaining a consistent clamp over time to limit seepage and keep engine bays cleaner.

• Washers distribute pressure to prevent cover distortion and gasket damage.
• Heat- and oil-resistant finish extends service life under engine conditions.
• Correct thread engagement restores factory-style clamping force.
• Eight-bolt kit replaces only the fasteners you need for standard covers.

What’s included and how easy is installation?

This purchase contains eight Nakonic valve cover bolts with matching washers—sufficient for a standard valve cover on most LS engines. Installation is straightforward for anyone comfortable with basic hand tools: remove old bolts, clean the seating surface, and torqueback to the manufacturer’s spec for a reliable seal.

• Package contains 8 bolts plus washers—ready for a single valve cover service.
• Requires basic hand tools and adherence to factory torque specs.
• Ideal for replacing damaged, corroded, or missing fasteners quickly.
• Contact Nakonic support if you’re unsure about fitment or installation steps.

Will these bolts improve reliability on a high-mileage LS engine?

Replacing old or compromised valve cover bolts with new hardware helps maintain a secure seal and can reduce oil seepage around the valve cover area. While bolts alone don’t repair gasket deterioration, they are a low-cost maintenance item that supports longer service life when used alongside a fresh gasket.

• Helpful maintenance step when replacing an aging valve cover gasket.
• New washers and bolts restore even clamping and reduce slow leaks.
• Durable finish reduces corrosion that leads to seized fasteners later.
• Not a substitute for a damaged valve cover or severely worn gasket.

Who is this for: Nakonic’s 8 PCS Valve Cover Bolts are aimed at do-it-yourselfers, mechanics, and restoration shops working on Chevrolet and GM LS-series engines from 1997–2014 who need reliable replacement fasteners. If you’re performing a gasket replacement, fixing oil seepage, or reinstalling a valve cover after maintenance, this kit offers a direct-fit, affordable hardware solution—just confirm your engine’s valve cover bolt pattern before purchase.
