Description

The Moroso 22121 is an extra-volume oil pump for GM LS engines. It delivers 33% more volume over stock Gen III LS pumps and offers standard volume for Gen IV engines equipped with DOD, AFM, and VVT. The pump includes a pre-installed 10 PSI higher pressure bypass spring, beneficial for vehicles with accumulators, oil coolers, or remote oil filters. It is compatible with stock timing covers and features a hard-coat anodized aluminum housing with a phosphate-coated cast-iron cover.
