The M54 engine has well documented issues caused by harmonics. The extreme vibrations cause the weak OEM oil pump shaft to shear off or cause the oil pump nut to come loose and fall off, all of which result in instant loss of oil pressure. We decided to develop a solution to fix all of these known issues.

We take our oil pump shafts to the extreme using only the toughest materials and heat treatment processes to ensure optimum strength. The core of our kit is a hardened chromoly shaft that is centerless ground to ensure absolute trueness. The shaft is engineered with an exclusive square key lock system that not only prevents the gear from ever spinning on the shaft but also adds strength to the area to which the gear mounts. We then replace the pesky oil pump nut with an extended length bolt that is EDM drilled for safety wire to properly secure it for all conditions. Don't wait for your oil pump to fail and leave you stuck with costly engine repairs!

Now included at no additional charge is our EDM Drilled Grade 8 Bolt and piece of safety wire to lay your worries to rest for good!
