Product Description

Boundary Lubrication Systems oil pump gerotors are the best insurance against catastrophic failure of the OEM oil pump.

The dramatically higher than stock power levels achievable with turbocharging subject the gerotor within the oil pump to vibration and harmonics that it was never intended to survive.

Boundary worked with metallurgists to find the best combination of steel grade and heat treatment to produce the best oil pump gerotor on the market.

Compare the billet steel used by Boundary and the compressed sintered (powdered) steel used in OEM oil pumps.

OEM gerotors are rated at only about 6000 PSI of yield strength.

The billet steel that Boundary uses is over 100,000 PSI in yield strength — around 18 times stronger than sintered steel.

For quality control, every billet steel gerotor can be traced back to its original material specification sheet.

NOTE: if you purchase the gerotor alone, you will need to have your existing (or new) oil pump housing machined in order to properly fit the gerotor into it. Complete plug-and-play new pumps with billet gerotors are available also.
