Speedmaster PCE289.1018 Compatible with Chevy 350 Complete 4 Bolt Splayed Steel Main Caps (5 Caps)

Speedmaster main caps are precision machined from superior-quality steel. They come available as stock replacements (straight bolt) or with splayed outer bolt holes. These extreme main cap sets consist of all 5 caps including the rear and front cap. Speedmaster main caps improve reliability in highly stressed engines by reducing distortion of the main bearing bores, and increasing the cap's resistance to closing up under high loads.
