We now stock brand new oil pumps that have been upgraded with our Oil Pump Upgrade Kits.
Just install and drive!
 

Unlike other "solutions" that only address one failure of the oil pump, our "Oil Pump Upgrade Kit" solves both issues the M50 family of oil pumps face: The gear retaining nut backing off the shaft, AND- sheering of the drive shaft mechanism.
Things that we have seen in an attempt to modify the OE pump mechanism are very susceptible to human error (welding the nut on, using wire to affix to the shaft, etc). Not only can these "fixes" fail, but they only truly solve half the problem!
The shaft sheering is not addressed in any other fix, still leaving this most important component vulnerable to an all too common damage.

Please do not underestimate the extremely common failure these engines experience! Pump failure is just the start as the result is very costly engine damage!
We feel that all modified street cars and of-course all vehicles that see track use MUST have this upgrade.
