Now part of the Clevite/Mahle family, Perfect Circle bearings deliver the precision and durability demanded by high-performance and competition engines.

H-Series Performance Features:

• Developed primarily for NASCAR-type racing but suitable for all competition engines
• Hardened steel back construction with thin overlay for maximum strength
• Medium level of eccentricity with high crush factor for secure fit
• Enlarged chamfers provide greater crankshaft fillet clearance
• Manufactured without flash plating for better seating and break-in
• 0.010 inch undersize for use with reground crankshafts

Application:

• Ford 351 Cleveland (351C) engines
• Ford 351 Modified (351M) engines
• 1970-1982 model years

H-Series bearings are specifically recommended for engines running in the medium-to-high RPM range and with crankshafts that have oversized fillets. The TriMetal construction provides superior load-carrying capacity while reducing friction for increased horsepower. Complete connecting rod bearing set included.
