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

Clevite H-Series bearings are built for performance, featuring medium eccentricity and high crush. This design helps them seat better and handle the stresses of medium to high RPM engine operation.

Why are these bearings made without flash plating?

The absence of flash plating on these bearings is intended to allow for better seating against the crankshaft. This ensures a more consistent and reliable connection for improved engine performance.

What kind of crankshafts are recommended for use with these bearings?

These H-Series bearings are recommended for use with crankshafts that have been machined with oversize fillets. This pairing helps to ensure proper fitment and performance in higher RPM applications.
