Clevite CB1663H10 High Performance Connecting Rod Bearing Set

The Clevite CB1663H10 is a high-performance connecting rod bearing set featuring H-Series construction designed for demanding racing and competition applications. Engineered with TriMetal construction, these bearings deliver the strength and durability needed for medium to high RPM engines while providing superior protection against friction and wear.

H-Series Performance Features:

• Medium eccentricity level optimized for balanced contact patterns covering 2/3 to 3/4 of bearing surface
• Hardened steel backing for maximum strength and resistance to fretting
• High crush design ensures positive bearing retention in the rod bore
• Thin overlay construction prevents overlay fatigue and hen tracking
• Enlarged chamfers provide greater crankshaft fillet clearance for performance cranks
• Non-flash plated for improved seating characteristics

Application Notes:

H-Series bearings are ideal for NASCAR-type racing and all forms of competition engines, particularly those with oversized crankshaft fillets running in medium to high RPM ranges. These bearings offer the best starting point when selecting performance bearings for racing applications. Each set includes two bearing halves for one connecting rod—order quantity to match your engine's cylinder count.

Clevite rod bearings are manufactured to meet or exceed OEM standards while incorporating performance enhancements that extend engine life under severe operating conditions. The precision-engineered TriMetal construction protects vital engine components from the destructive effects of friction and heat.
