Clevite GMC Pass & Trk 348 366 6.0L 396 402 409 427 7.0L 454 7.4L 502 Con Rod Bearing Set

This product includes a set of Clevite H-Series connecting rod bearings. These bearings are built with a hardened steel back and a thin overlay, and they are made without flash plating to help them seat better. They are designed for engines that operate in the medium to high RPM range, especially when paired with crankshafts that have oversize fillets. This set is suitable for a wide range of GMC and Chevrolet V8 engines, including popular applications like the 348, 396, 454, and 502 cubic inch displacements.

The H-Series bearings feature a medium level of eccentricity and high crush, which are important characteristics for proper engine function at higher RPMs. The hardened steel back provides a solid foundation, while the thin overlay helps to manage friction and wear. By omitting the flash plating, Clevite ensures a more direct and secure fit against the crankshaft journal, which is crucial for oil film control and bearing longevity in performance applications.
