The "Pro-Just" is designed exclusively for Harley Davidson motorcycles. To be specific, the PJ-2 is engineered for the models of Harley Davidson motorcycles known as the "Evolution".
After the development of the PJ-1 for the "Shovelheads", we turned our attention to the newest model, the "Evolution". The "Evo", while still using the same style of oil pump as the "Shovelhead", did have some differences. The main
difference was that the pressure relief cap was counter bored to fit into the body of the oil pump, instead of sitting on top. The new cap also sealed with an o-ring instead of the teflon gasket. So, back to the drawing board we went! We incorporated the new PJ-2 with a smaller outer diameter so it would fit inside of the oil pump's
counter bore along with an o-ring to ensure that it sealed properly. With that, we would like to introduce the PJ-2 "Pro-Just"
The "Pro-Just" is an adjustable pressure relief cap that allows the precise adjustment of oil pressure. Each body is made from "BILLET" 6061 aluminum and is
counter bored to accept an o-ring which seals around a knurled stainless steel thumbscrew that provides the adjustment. Each kit includes the "blue" spring from the "Superpump-Kit" and an o-ring that seals to the oil pump.
E.R.T. Products, Inc. is proud to offer our Harley Davidson parts for your Harley Davidson motorcycle! As with all of our Harley Davidson parts, the PJ-2 comes with a one year warranty.
