For engine builders performing a major overhaul on an FA20 engine, these .25mm oversized rod bearings from ACL are an essential component. Designed to accommodate a crankshaft that has been ground down by .25mm, these bearings restore factory-spec clearances while offering the enhanced durability of the ACL Race Series.
ACL Race Series bearings are engineered to withstand the rigors of high-RPM operation and increased cylinder pressures. By utilizing a high-strength tri-metal design, these bearings offer superior fatigue resistance compared to standard replacements. They are the ideal choice for anyone looking to build a reliable, high-performance engine for their BRZ, 86, or FR-S.
Precision machining requires precision parts. These bearings ensure that your engine build maintains the structural integrity required for both street and track performance. Upgrade your engine internals with confidence using high-quality components from GGCRACING.
