What is the main advantage of Clevite H-Series bearings?

Clevite H-Series bearings are designed for performance applications. They feature medium eccentricity and high crush, which helps them seat well on crankshafts with oversize fillets and perform reliably in medium to high RPM engines.

Why are these bearings made without flash plating?

The absence of flash plating allows these bearings to seat better against the crankshaft. This improved seating is important for maintaining consistent oil clearance and ensuring proper load transfer during engine operation.

What kind of crankshafts are these bearings best suited for?

These bearings are recommended for use with crankshafts that have oversize fillets. The H-Series design, with its medium eccentricity and high crush, is specifically beneficial in these applications.

Product Details

If you're rebuilding the bottom end of a performance V8 engine, especially one that sees medium to high RPMs, a solid set of connecting rod bearings is crucial. These Clevite H-Series bearings are built for that kind of work, offering a well-built hardened steel back with a thin overlay. They're made without flash plating, which helps them seat better against the crankshaft. This is important for ensuring consistent oil clearance and proper load distribution.

The H-Series design includes a medium level of eccentricity and high crush, features that are beneficial when you're working with crankshafts that have oversize fillets. This design helps the bearings conform to the crankshaft journal, providing a stable platform even under demanding conditions. They are a popular choice for engine builds where reliability at higher RPMs is a priority.
