Mopar Flywheel Bolt Kit - 1/2

The ARP Mopar Flywheel Bolt Kit - 1/2 is engineered for serious engine builders and performance enthusiasts who demand reliability during high-stress clutch engagement cycles. As a mechanic who has rebuilt countless Mopar platforms, I can confirm that factory flywheel fasteners are often a weak point in the power transmission chain, especially on modified or turbocharged applications. This kit addresses that critical vulnerability by replacing OEM bolts with premium ARP fasteners, which are essential for maintaining clamping force under extreme loads and preventing catastrophic flywheel separation.

ARP's proprietary manufacturing process produces fasteners with superior tensile strength and consistent preload characteristics compared to stock hardware. The 1/2-inch sizing indicates these are full-diameter bolts designed to secure larger, heavier flywheels common to big-block Mopar engines and performance-upgraded applications. The kit's precision engineering ensures uniform clamping loads across all fastening points, which is critical for preventing harmonic imbalance, flywheel runout, and premature clutch wear. Whether you're running a street machine or a dedicated drag racer, the molecular-grade steel used in ARP fasteners resists fatigue cracking and galling that can plague standard hardware in high-cycle applications.

This flywheel bolt kit is ideal for anyone upgrading to a higher-stall converter, installing a performance clutch, or building a modified engine that exceeds factory power output. The 1/2-inch bolts fit Mopar-specific flywheel designs and are commonly specified for 340, 360, 383, 400, 426, and 440 cubic-inch engines with modern or period-correct flywheels. Installation is straightforward for experienced builders—simply remove the original bolts, clean the flywheel bolt holes thoroughly, and install the ARP fasteners using a torque wrench to the manufacturer's specification. For maximum longevity and clamping integrity, apply a light coat of ARP Ultra-Torque or similar assembly lubricant to each fastener before installation.
