In high horsepower engines the block can flex resulting in abnormal bearing wear damaging your crankshaft and other high dollar parts in your block. By installing billet main caps, you reduce the flex of the block resulting in a stronger bottom end. These BMW M5x/S5x main caps are carefully crafted, in-house, from 1050 steel. They are finished with a black oxide coating for corrosion resistance. They provide extreme rigidity to the main bearings and crankshaft, which is a necessity for high horsepower engines. In addition, the large profile and high strength material is much stronger and stiffer than the factory main caps. Help protect your expensive investment with these simple factory replacement billet main caps.
Features:
Crafted from 1050 steel
Coated with black oxide for resistance against corrosion
A must for high horsepower applications
