Probe Industries Billet Steel Main Caps are made from precision-machined high strength 1045 billet steel, which has the proper balance of strength and flexibility to allow transfer of increased shock loads to the crank and bearings. These main bearing caps will improve your engine performance and reliability by eliminating main cap walk and reducing main bearing bore distortion. Probe Billet Steel Main Caps offer excellent strength at a reasonable cost.
