Give your crankshaft a fresh, precisely-fitted set of bearing surfaces with the Sealed Power Engine Crankshaft Main Bearing Set 7211M. Main bearings support the crankshaft in the engine block and provide the load-carrying surfaces it rides on over a film of oil. This set drops in as a direct-fit replacement for the 1991-2001 Jeep Cherokee, 1991-1992 Jeep Comanche, 1993-2004 Jeep Grand Cherokee, 1997-2004 Jeep TJ, and the Jeep Wrangler (1991-1995 and 1997-2004) — all with the L6-4.0L engine.
If worn main bearings are the cause of a deep engine knock or low oil pressure, this Premium-grade set replaces them during an overhaul or reseal — diagnose the source of the noise or pressure loss before replacing. The listed applications use one set per engine. Country of origin: Mexico. Manufacturer part number 7211M.
