Clevite H-Series rod bearings were developed primarily for use in NASCAR type racing but are suitable for all types of competition engines. These H-Series bearings have a medium level of eccentricity, high crush factor, and have hardened steel backs and thin overlays. They also have enlarged chamfers for greater crankshaft fillet clearance and are made without flash plating for better seating.

Bearings with .001 in. extra clearance are available for standard size shafts and with or without dowel holes. H-Series bearings are recommended for use with crankshafts that have oversize fillets and where engines run in the medium to high rpm range. They should also be used if contact patterns obtained with Clevite P-Series bearings are too narrow. Contact patterns should ideally cover 2/3 to 3/4 of the bearing surface.

How many of these would I need?

A:

Quantity 8 for V8. Each box has 2 half shell bearings, so one box is enough to do one rod.

Would this be a good bearing for daily driving

Asked by STEVEN on August 11, 2019

A:

I think it would. I use them in my race motor. I have used the same set of bearings thru 3 ring changes because they always looked like new.
