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 VR6 (R32) 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.
Supplied with all bolts (12.9) and washers necessary for installation.
