As the cap collapses, the dimension across the parting line becomes smaller, eventually causing the edge of the bearing to begin scraping oil off the crankshaft, leading to bearing and crank failure. SoCal Diesel main caps solve the collpase issue by using high strength aircraft quality steel. Blanchard ground, precision machined. Recommended for engines above 800 RWHP.
