When rebuilding your FA20 engine, precision is everything. These ACL Race Series .025mm oversized rod bearings are designed to provide the perfect fit for machined or undersized crankshafts. Built for the high-performance demands of the Subaru BRZ, Scion FR-S, and Toyota 86/GR86, these bearings ensure long-lasting reliability under stress.
ACL Race Series bearings are renowned for their high-strength tri-metal construction, which provides excellent resistance to surface fatigue and wear. The .025mm oversized specification allows for precise clearance adjustments when your crankshaft has been polished or machined, maintaining optimal oil pressure and film thickness.
Don't settle for OEM tolerances when building a performance engine. These bearings are designed to handle the heat and pressure of modern high-output engines, ensuring your build stays together under load. Find all your essential engine components at GGCRACING.
