Keep the crankshaft turning true with the Sealed Power engine crankshaft main bearing set 7144MA — an application-specific set of crankshaft main bearings that support the crankshaft in the block and provide the bearing surface for its rotating main journals. It installs as a direct-fit replacement across a wide range of GM engines, including the V6-3.0L, V6-3.2L, V6-3.3L, V6-3.7L, V6-3.8L, V6-4.1L and the V8-5.0L, spanning Buick, Chevrolet, Cadillac, GMC, Jeep, Oldsmobile and Pontiac models — see the Buyer's Guide tab for the full list.

  • A-Series bi-metal aluminum alloy: made with silicon to provide greater surface hardness.
  • Greater seizure resistance than tri-metal material.
  • Reduces dramatically or eliminates bearing wear.
  • Exacting tolerances that meet or exceed OEM specifications.

Worn main bearings can show up as a deep knocking noise, low oil pressure or metal traces in the oil; if the original bearings are the cause, this set replaces them during a rebuild or overhaul. Country of origin: Mexico.
