Maximize Bottom-End Stability

The Mopar 318 and 340 small block engines are known for their power potential, but they require a robust bottom end to handle high-performance upgrades. Milodon Splayed 4-Bolt Main Caps are the ultimate solution for preventing main cap walk and ensuring crankshaft stability under extreme load. By converting your block to a splayed 4-bolt configuration, you significantly increase the structural rigidity of the main bearing saddles.

Engineered for Durability

  • Ductile Iron Construction: Offers superior strength and vibration dampening over standard cast iron.
  • Splayed Bolt Design: Anchors the caps into the strongest part of the block webbing.
  • Precision Fit: Designed specifically for Mopar 318/340 blocks for a secure, professional installation.
  • 4-Bolt Conversion: Provides the necessary support for high-RPM and high-torque racing applications.

Proper main cap support is critical for engine longevity. These Milodon caps are designed to be line-bored to your specific block, ensuring a perfect fit and ideal bearing clearance. Whether you are building a high-compression street engine or a dedicated drag racing powerplant, these main caps are an essential upgrade for any serious Mopar enthusiast. Invest in the foundation of your engine with high-quality components from GGCRACING.
