This ACL Race Series main bearing set is an oversized 0.50 kit for VW/Audi 1781cc/1984cc engine rebuilds where increased bore size is required. The set includes six bearings with oil grooves and four without; the #4 journal receives oil grooves on both sides while the remaining grooved bearings are on the block side only. These bearings help restore correct clearances and oiling when machining to an oversize specification.
