These main caps are specially designed to work with a crankshaft girdle plate. Typically, the installation of girdle products requires machining small spacers, which go between the main cap and the girdle, bringing it up to the same level as the pan rails. We have found that using spacers is very difficult to machine to the correct height, even when done with extreme care. Often times this process compromises the installation and results in a warped girdle.IE Tall Boy Main Caps offer the ultimate solution, standing slightly proud of the pan rail as they come out of the box. They are then machined level with the pan rail, resulting in a perfectly flat surface for the installation of your girdle plate, and the most rigid foundation for your crankshaft possible.
WHEN TO UPGRADE YOUR MAIN CAPS. The stock main caps are cast and lack the rigidity required for a reliable high powered build. We recommend upgrading to a set of IE Billet Main Caps when building a performance engine exceeding 500HP, or when installing a girdle kit to help reduce crankshaft and main bearing wear.
These for VW/Audi 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 for stiffer than the factory main caps.
