PART NO. APPLICATION DESCRIPTION

High volume performance upgrade for M-55HV. 25% increase in volume over stock oil pump. The 10550 housing and cover are
10550 GM S.B. Performance Oil Pump Line CNC machined and phosphate coated. The lower pressure spring is included to reduce pressure if desired. Includes intermediate shaft with steel guide.
Built with billet steel gears. Uses 5/8” press in screen.
10552 GM S.B. Performance Oil Pump Line High volume performance oil pump. 10% increase in volume over stock oil pump. The 10552 is manufactured with the drive and idler shafts extended
to allow for additional support in the cover eliminating dynamic shaft deflection at increased RPM levels. Uses both 3/4” bolt on or press in screen.
GM S.B. Performance Oil Pump Line High volume performance oil pump. 10% increase in volume over stock oil pump. Same as the 10552 with the addition of grooves machined in the
10552C body and cover. The grooves reduce cavitation effects in high RPM applications. Includes 12550 chrome moly intermediate shaft with steel guide. Built with billet
(Anti-Cavitation) steel gears. Uses both 3/4” bolt on or press in screen. The 10552C uses the high pressure spring only. Racing Applications Only.
High pressure performance upgrade for M-55 & M-55A. Standard volume oil pump. The 10553 housing and cover are CNC machined and phosphate
10553 GM S.B. Performance Oil Pump Line coated. Manufactured with pink spring installed for higher pressure (M-55A). To change pump to lower pressure (M-55) install the supplied yellow spring.
Includes intermediate shaft with steel guide. Built with billet steel gears. The 10553 uses a 5/8” press in screen.
High Volume performance upgrade for the 10550 oil pump. 25% increase in volume over stock oil pump. The 10555 is manufactured with the drive
10555 GM S.B. Performance Oil Pump Line and idler shafts extended to allow for additional support in the cover eliminating dynamic shaft deflection at increased RPM levels. Includes 12550 chrome moly
intermediate shaft with steel guide. Built with billet steel gears. Uses both 3/4” bolt on or press in screen.
GM S.B. Performance Oil Pump Line High volume performance upgrade for the 10550 oil pump. 25% increase in volume over stock oil pump. Same as the 10555 with the addition of
10555C grooves machined in the body and cover. The grooves reduce cavitation effects in high RPM applications. Includes 12550 chrome moly intermediate shaft with
(Anti-Cavitation) steel guide. Built with billet steel gears. Uses both 3/4” bolt on or press in screen. The 10555C uses the high pressure spring only. Racing Applications Only.
High volume performance upgrade for M-77HV. 25% increase in volume over stock pump. The housing and cover are CNC machined and phosphate
10770 GM B.B. Performance Oil Pump Line coated. The lower pressure spring is included to reduce pressure if desired. Built with billet steel gears. Includes intermediate shaft with steel guide.
