Nakonic Valve Cover Bolt Kit for Chevy & GM LS Engines — 8-Piece Set with Washers (1997–2014)

Nakonic 8-piece valve cover bolt kit replaces worn or missing bolts on Chevy and GM LS-series engines from 1997–2014 to restore secure, leak-resistant valve cover clamping.

This Nakonic kit contains eight replacement valve cover bolts engineered specifically for many Chevrolet and GM LS-family engines—covering popular 4.8L through 6.2L variants and multiple LM/LQ/LR engine codes. Each bolt includes a washer to spread clamping load and resist vibration, heat, and oil exposure common in engine compartments. The set is a straightforward, affordable maintenance item for mechanics, DIY enthusiasts, and shops that service LS engines.

Which LS engines will these bolts fit?

These bolts are designed for a broad range of LS-series Chevrolet and GM engines produced between 1997 and 2014, including many Vortec truck engines. They fit LS1, LS2, LS3, LS6, LS7, LS9 and a wide selection of L-series variants used in trucks and performance cars.

• Compatible: GM 4.8L, 5.3L, 5.7L, 6.0L, 6.2L engines and many L-series codes (LQ4, LQ9, LM7, LR4, L33, etc.).
• Includes washers to reduce local stress on valve covers and help prevent leaks.
• Sold as an 8-piece kit—sufficient for one bank on many engines or for full-service replacements depending on factory bolt count.

How do these bolts hold up to engine heat, oil, and vibration?

Nakonic designed this kit with materials and washers intended to resist engine heat, oil, and the vibration typical of V8 and truck powerplants. The construction helps keep clamping force consistent over time to reduce the chances of gasket creep or oil seepage.

• Washers distribute torque to protect valve cover flanges from overtightening damage.
• Corrosion-resistant finish to withstand oil and moisture exposure.
• Engineered for repeated removal and reinstallation during maintenance.

Are there any fitment exceptions or vehicles to avoid?

Yes—these bolts are not compatible with early LS engines that use perimeter-bolt valve covers. Vehicles such as 1997–1998 Corvette, Camaro, and Trans Am models with LS1 perimeter bolt covers require different hardware.

• Not for 1997–1998 LS1 perimeter-bolt valve covers—verify your cover style before ordering.
• Check your engine code and production year against the listed compatible models to confirm fitment.
• If unsure, compare existing bolt footprint and washer diameter to confirm match.

What comes in the package and what should I expect during installation?

The package includes eight valve cover bolts with washers ready for direct replacement. Installation is a basic mechanical task: remove old bolts, clean the sealing surface, position the gasket and cover, then torque the new bolts to the vehicle manufacturer’s specifications.

• Package: 8 Nakonic bolts with washers—no additional hardware included.
• Installation tip: use a calibrated torque wrench and follow OEM torque sequence for even clamping.
• Contact Nakonic support if bolt fitment or installation questions arise.

Who is this for: This Nakonic 8-piece valve cover bolt kit is ideal for automotive technicians, restoration projects, and DIYers working on GM LS-series engines who need reliable replacement hardware. It suits owners of trucks, performance cars, and swap builds that use compatible LS blocks and want straightforward, durable valve cover fasteners without needing specialty parts. Avoid this kit only if your vehicle uses perimeter-style valve covers from early LS1 installations.
