These VW VR6 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 VR6 billet main caps.
Requires machine work including align bore & hone for fitment.
Main journal housing bore size: 2.3228"-2.3236".
