Mopar V8 Main Bolt Kit - 273-440 Wedge 2-Bolts

The Mopar V8 Main Bolt Kit - 273-440 Wedge 2-Bolts from ARP is an essential upgrade for serious Mopar builders and restoration shops working with classic Chrysler wedge-head engines. This kit is specifically designed for engines with a two-bolt main cap configuration, ensuring compatibility with the original casting design of wedge-head main caps.

Engineered from proprietary high-strength alloy steel, these fasteners provide reliable clamping force in the engine's main bearing caps. The bolts are shot-peened and stress-relieved to eliminate fatigue failure points, ensuring superior tensile strength that prevents bolt stretch and crankshaft movement, which can lead to bearing wear and upper-end noise.

Technicians and engine builders rely on this kit for complete rebuilds, performance upgrades, or when upgrading older cores to modern reliability standards. Ideal for hot rod applications and restoration projects, this kit helps maintain the integrity of your engine's performance.
