INFO

This aftermarket standard-volume engine oil pump is configured for the documented GM Gen III and Gen IV LS V8 lubrication-system applications. The polished cast-aluminum housing contains precision steel gears, uses a four-hole mounting configuration, and is crankshaft driven for pressure lubrication. The recorded engine family includes selected 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L applications. The package contains one oil pump and two O-rings. Recorded interchange numbers identify the replacement family and do not represent the pump as a genuine General Motors component.

This is the standard-volume configuration, which distinguishes it from the separately listed high-volume pump. An oil pickup tube, pickup screen, oil pan, timing cover, timing components, gaskets, sealant, fluids, sensors, and installation hardware not shown with the package are not included. The pump mounts at the front of the engine within the lubrication system. Oil pressure after installation depends on the complete system, including pickup sealing, oil passages, bearing clearances, relief operation, oil viscosity, and remaining engine condition; the pump is not represented as correcting unrelated wear. The standard-volume pump style and included O-rings distinguish this SKU from the separately listed high-volume configuration.

Features

  • One standard-volume GM Gen III/IV LS V8 oil pump.
  • Two oil-pump O-rings are included.
  • Polished cast-aluminum housing with precision steel gears.
  • Four-hole, crankshaft-driven front-engine configuration.
  • Recorded for documented 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L applications.
  • Pickup tube, pan, timing parts, gaskets, fluids, and unlisted hardware are not included.
