ARP Head Bolt Kits | Multiple Chrysler Fitments (145-3607)

The ARP High Performance Series Head Bolt Kit is a set of high-strength fasteners designed for demanding engine applications. Constructed from chromoly steel with a black oxide finish, these head bolts are rated at 180,000 psi, making them 15 percent stronger than standard Grade 8 fasteners. The kit features either a reduced wrenching hex head or 12-point head, facilitating easier re-torque procedures without the need to remove valvetrain components. These bolts provide enhanced durability and reliability under high-stress conditions, ensuring secure cylinder head retention during aggressive driving or high-performance use. Their robust construction and precision engineering make them a preferred choice for engine builders seeking strength and ease of installation.

Designed for a variety of Chrysler applications, these ARP head bolts are suitable for engines requiring high-torque head fasteners. They are compatible with multiple Chrysler models and fitments, serving as direct replacements or upgrades for stock fasteners. The kit includes washers and is intended for use in performance, street, or track environments where engine integrity is critical. Installation involves standard bolt replacement procedures, and the bolts are ideal for rebuilding or upgrading engines that demand superior clamping force. These head bolts are engineered to withstand extreme conditions, providing long-lasting performance and peace of mind in high-performance automotive builds.
