Splayed Center Main Caps - SBC

The Splayed Center Main Caps - SBC by PRO-GRAM ENGINEERING are designed for Small Block Chevy engines, catering to serious engine builders and high-performance mechanics. These caps are essential for those looking to enhance crankshaft support and rigidity, whether for street performance or high-RPM applications.

Engineered with a splayed design, these main caps effectively distribute load across the block's webbing, reducing deflection and improving engine stability. This innovative geometry increases bearing surface contact area, addressing a known weakness in stock SBC architecture. The precision manufacturing ensures consistent bore sizing and cap alignment, which are critical for preventing bearing wear and crankshaft failure.

Ideal for high-performance applications, these caps are particularly beneficial for engines subjected to boost, nitrous, or high-cubic-inch naturally aspirated scenarios. Their robust construction signals durability, making them a vital upgrade for any Small Block Chevy engine builder aiming for peak performance.
