SBF 351C Main Bolt Kit w/4-Bolt Main

The SBF 351C Main Bolt Kit w/4-Bolt Main from ARP is designed for serious engine builders and high-performance enthusiasts focused on enhancing crankshaft reliability in small-block Ford 351C applications. This kit is essential for those building stroker engines, increasing boost pressure, or pushing naturally-aspirated horsepower beyond factory limits.

Engineered to address the critical weak points in 351C four-bolt main architecture, this kit replaces factory hardware with premium ARP fasteners. These fasteners are manufactured from ultra-high-strength alloy steel and are designed to handle extreme cylinder pressures and rotational forces, ensuring consistent preload and clamping force across all main cap fasteners.

Ideal for high-performance and stroker builds, this kit is perfect for those assembling vintage 351C engines for classic vehicles. By utilizing superior fasteners, builders can achieve optimal main cap torque specifications, reducing the risk of fastener yielding or stretch failure during operation.
