Description
These VW 4 cylinder main caps are carefully crafted, in-house, from USA 4140 alloy steel. They provide extreme rigidity to the main bearing 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. If you are using a girdle, please purchase our Tall Boy VW 4 Cylinder billet main caps. Requires machine work including line bore & hone for fitment.
