ACL Bearings 5M8632H-.025 Race Series Main Bearing Set

The ACL Bearings 5M8632H-.025 is a Race Series main bearing set engineered for Toyota 1UR-FE, 2UR-FE, and 3UR-FE V8 engines, specifically designed for high-performance and durability under extreme conditions. This 0.025mm oversized bearing set is .0005" thinner per half to give .001" extra clearance for standard sized crankshafts.

Key Features:

• High strength overlay plate with reduced thickness for enhanced performance and improved fatigue properties
• Hardened steel backs on all rod bearings to improve support of the bearing lining and assist with bearing retention in the housing
• Increased crush designed to eliminate flash plating and improve reliability
• 3/4 grooving on main bearings for optimal oil supply and load carrying surface area
• Consistent wall tolerances ensure tight and reliable fitment
• Increased eccentricity to compensate for bore distortion at high RPM and assist in hydrodynamic oil film formation

These tri-metal bearings are engineered for high RPM applications and are perfect for 4, 6, and 8 cylinder engines, ensuring smooth operation even at higher RPMs. Ideal for performance builds, forced induction applications, and racing environments where standard bearings may not provide adequate protection.
