ACL Trimetal Reinforced Rod Bearings – BMW V8 S63B44 (4.4L biturbo, M5, M6, M8, X5M, X6M) & N63B44

Designed to withstand high RPM, temperatures and load, these high strength bearings are manufactured by ACL from 3 layers of hardened steel, copper and nickel. This “trimetal” composition substantially lowers friction, and thus reduces the operating temperatures while providing superior lubrication.

These bearings are sold in complete sets (for a complete engine).

If you require non-standard grade bearings or HX references, or are performing an engine rebuild, feel free to contact us for a detailed quote – we stock many internal parts, and can provide most required for complete engine repair.
