Description
These VW 4 cylinder main caps are carefully crafted, in-house at Integrated Engineering, 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 the "Tall Boy" VW 4 Cylinder billet main caps ES2794526.

***Main journal housing bore size: 2.3228"-2.3236".
