Product Description

The ACL 5M2964H-STD Race Main Bearing Set is engineered for high-performance applications, offering superior durability and reliability under extreme conditions. These bearings are designed to withstand high RPM and high-stress environments, making them ideal for performance builds and racing applications.

Constructed with a trimetal design, the bearings feature a hardened steel backing to maintain crush under high loads and temperatures. The increased crush and tighter wall tolerances ensure better seating, while the improved overlay and reduced thickness enhance fatigue strength. Additionally, the large chamfer accommodates larger crankshaft fillets, and the 3/4 groove main bearings optimize bearing load carrying capacity and oil flow to rod bearings.

Compatible with Nissan SR20DE and SR20DET engines found in various models including the 1991-2001 Nissan 240SX (S13/S14/S15), Sentra, 200SX, NX, and Infiniti G20, this bearing set is a reliable choice for engine builders seeking per:contentReference[oaicite:5]{index=5}
