Main bearing shells (repair rib: 0.001") Standard ACL for Renault (F4R)
ACL Race Series crankshaft bearings are renowned for their reliability in extreme conditions. Designed for Renault F4R R3 engines, these tri-metal alloy bearings (hardened steel, copper, lead, tin) offer micrometric tolerance suitable for competition and engine tuning.
Thanks to their reduced thickness of 0.001’ (0.025 mm), they guarantee superior running clearance, improving oiling, reducing internal friction and lowering engine operating temperatures. All this without compromising reliability, even at high engine revs.
