ARP Chromoly Pressure Plate Bolt Kit for GM LS-Series 12" Clutch — Black Oxide Hex Head, High-Strength

This bolt kit bundles high-strength chromoly fasteners with a durable black-oxide coating and a hex-head drive pattern designed for professional installers and enthusiasts working on GM LS-series 12" clutch systems. ARP bolts are made to withstand repeated torque cycles and the rigors of high-performance drivetrains, offering a reliable aftermarket replacement or upgrade for worn or missing pressure-plate hardware.

How does this bolt kit improve clutch assembly reliability?

Using chromoly bolts designed specifically for pressure plates reduces the risk of fastener stretch, breakage, or fatigue under high clamp loads. The black oxide finish adds mild corrosion resistance and reduces glare during installation, while the precise hex-head geometry ensures consistent torque application.

• Chromoly construction for higher tensile strength compared to standard steel
• Black oxide finish resists surface rust and eases handling
• Hex-head drive for secure socket or wrench engagement
• Engineered for repeated torque cycles common in clutch service

Will these bolts fit my GM LS-series 12-inch pressure plate?

The kit is specified for 12" clutch pressure plates used on GM LS-series applications; fitment aligns with OEM-style bolt patterns and torque requirements for those systems. Always verify your pressure plate's bolt-hole spacing and thread engagement depth before installation to confirm compatibility.

• Designed for 12-inch diameter pressure plates
• Matches GM LS-series bolt patterns and OEM-style fasteners
• Sold as a complete kit to replace all pressure-plate attachment points

What installation and maintenance practices should I follow?

Torque bolts to the pressure plate manufacturer's specified value using a calibrated torque wrench and follow a crisscross tightening sequence to center the plate and prevent distortion. Inspect bolt threads and mating holes for damage, and replace any damaged hardware rather than reusing worn fasteners.

• Use manufacturer-specified torque settings and sequence
• Apply anti-seize or threadlocker only if the pressure plate manufacturer recommends it
• Replace bolts if any signs of thread wear, corrosion, or stretching appear

What are the kit's packaging and physical details?

The bolts arrive as a new sealed kit sized for easy storage and shipping. The compact package contains all required fasteners and is lightweight for transport and staging in a workshop environment.

• Item package dimensions: 5.7087 L x 3.8976 W x 0.5906 H inches
• Package weight: approximately 0.366 pounds
• Sold as a single kit intended for one 12" pressure plate installation

Who is this for? This ARP pressure plate bolt kit is aimed at professional mechanics, race teams, and DIY automotive enthusiasts rebuilding or upgrading 12-inch clutches on GM LS-series engines. If you need bolts designed to meet the higher stresses of performance drivetrains and want a direct-fit aftermarket option with improved tensile strength and corrosion protection, this kit provides a practical, workshop-friendly solution.
