Clevite Standard OEM Replacement Rod Bearings Set - (All SOHC+DOHC 4.6L)

Clevite 77 engine bearings are built above industry standards for strength and durability ?even exceeding the highest standards set by Heavy Duty engine manufacturers. The majority of Clevite 77 engine bearings utilize a superior TriMetal design first developed by Clevite 50 years ago and perfected over time. This design incorporates the strength of a copper-lead alloy layer on a precision steel back and finally, a precision electroplated white metal "babbitt" surface layer. TriMetal is an ideal design, producing a degree of conformability, embedability, slipperiness and fatigue resistance, not found in many original equipment and competitive bi-metal bearings.

All Clevite 77 Engine Bearings manufactured by us are color coded for quick and positive identification of undersizes. The possibility of confusion or errors in installation is virtually eliminated by checking the color code on the side of each bearing.

Clevite 77 has an extensive, long-standing history with racing. Our Clevite 77 product has been winning NASCAR-sanctioned races since 1948, and is the exclusive bearing of NASCAR Performance.Learn More
