Main Bearing Girdle for all four cylinder chain driven oil pump applications like the 1.8T engines.
VW and Audi blocks are notorious for a lack of lateral support at the crankshaft center line. This lack of support can lead to the block and crankshaft bending under high loads. This can lead to excessive bearing wear and block failure. The main bearing girdle prevents distortion and misalignment of the main bearings under extreme performance applications. A must for all high boost turbo applications. The main bearing girdle also acts as an oil scraper due to its unique design. Installation requires machining of individual bearing cap spacers.
On some engines the oil sump needs modifications. Please see the attached instruction.
