ACL Race Big End Bearings (S50B32)
ACL Race Series big end bearings for the S50B32 engine, as found in the E36 M3 Evo and early Z3 M. ACL bearings are a vital upgrade that increase the life and strength of your S50.
Choose from OE size, or HX series for an extra .001″ oil clearance. Oversizes available by request. Combine with ARP connecting rod bolts for the perfect upgrade.
Why not add a bottle of Hack Engineering Engine Assembly Lubricant to protect your new bearings on first start up?
