Main Bearing Set
(0.25mm / .010")
Clevite 77 engine bearings have set the pace for engineering quality. 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 Tri-Metal 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. Tri-Metal is an ideal design, producing a degree of conformability, embeddability, slipperiness and fatigue resistance, not found in much original equipment and competitive bi-metal bearings. LC Engineering uses only Clevite Bearings in all 20R/22R/RE applications.
NOTE: This bearing set will have Offset/Center locating tabs.
