  • Connecting Rod Bearings

  • M Series Bearings - Steel backed bearings with a Micro-Babbitt lining. Precision undersizes are not resizable

  • Clevite is a name engine builders trust, world wide. Clevite cast copper-lead engine bearings, developed and proven over decades, set the industry standard for engineering quality. In addition to Clevite engine bearings being the only engine bearings of NASCAR Performance, they succeed on straight tracks as well. Every top NHRA nitro-fueled team puts their trust in Clevite. The P-series rod bearings typically have the greatest amount of eccentricity. Most P-series main sets maximize oil flow to the rod bearings. Both rods and mains have high crush for maximum retention, and a reduced overlay thickness to prevent overlay fatigue. Rod bearings use a hardened steel back for added strength and resistance to fretting. Extra clearance rod bearings are available for .001'' additional clearance and select fitting. Use P-series mains where higher eccentricity is desired to narrow bearing contact patterns and to provide increased oiling to rod bearings.

  • High crush for better seating and retention
  • High eccentricity accommodates rod bore distortion
  • Strong, extra-thin overlay to withstand high loading and resist flaking
  • Hardened steel backing for greater strength

    Note: Clevite main and cam bearings are priced as sets and rod bearings are priced each (unless noted)

  • Some parts are not legal for use in California or other states with similar laws / regulations
