King Engine Bearings CR1057GPC.026 pMax Black Connecting Rod Bearing Set 0.026" Undersize

The King Engine Bearings CR1057GPC.026 is a precision-engineered connecting rod bearing set from King's pMax Black™ performance bearing line. Featuring an 0.026-inch undersize specification, these bearings are designed for use in applications requiring a slightly reduced journal diameter — typically following a crankshaft grind or when working with a worn crankshaft that has been machined to restore proper surface geometry.

pMax Black™ Technology:

• Tri-metal construction — steel backing, copper-lead or aluminum alloy intermediate layer, and a premium overlay for superior wear resistance
• Black PTFE-based polymer coating on the bearing surface reduces friction during initial start-up and break-in, protecting against metal-to-metal contact
• Enhanced fatigue strength suitable for high-performance, turbocharged, and high-output naturally aspirated engines
• Precision tolerances machined to King's exacting standards for consistent oil film and proper clearance
• 0.026" undersize — designed for crankshafts ground 0.026" under standard journal diameter
• Meets or exceeds OEM fit, form, and function requirements
