The ARP Main Bolt Kits are high-performance cam drive bolt sets designed to ensure optimal timing gear registration and reliability. Manufactured by ARP, these bolts feature increased preload clamping force to maintain precise cam timing under demanding conditions. Constructed from high-strength materials, available in 170,000 psi and 190,000 psi variants, they provide superior resistance to valvetrain harmonics and stress. The reduced head size facilitates easier installation and removal, making them suitable for both professional and enthusiast applications. These kits are engineered to deliver consistent performance and durability, ensuring the integrity of the timing system during high-performance driving or engine rebuilds.

Designed for multiple Ford applications, including the Ford 6.2L V8, these bolt kits serve as direct replacements for stock components. They are ideal for street, track, or off-road use where reliable timing gear engagement is critical. The bolt kits are suitable for engines requiring increased clamping force to prevent gear slippage and maintain proper valve timing. Installation is straightforward, with all necessary bolts included in the kit. These ARP cam drive bolt kits provide a robust upgrade to enhance engine reliability and performance in various Ford models.
