When they are gone that is it. Get them while you can. This is not a sales pitch.

It will now be up to one of you to invest your over one hundred thousand dollars to have them made and get it back one hundred dollars at a time.... Stock is now down to critical level! These MADE IN USA oil pump drive gear sets double the oil pump speed on 1973-89 model Big Twins and more than double the speed on 1954-72 They can be used in Panhead, Shovelhead and Evolution engines 1954-89 They can also be used in S&S Jims Ultima TP Delkron Merch and custom build engines using pre 1990 style pinion shafts.

OEM Harley Big Twin engines up to and including 1972 used a 25T gear on the oil pump shaft and a 6T gear on the pinion shaft giving a 5:1 ratio. (5 engine revolutions for every 1 oil pump revolution) In 1973 Harley changed the oil pump shaft gear to from 25T to 24T and the pinion shaft gear from 6T to 5T giving a 4:1 ratio.

(this changed increased the oil volume approximately 25%) These gears have 22T on the oil pump shaft gear and 11T on the pinion shaft gear giving a 2:1 ratio. This further increases volume for improved cooling and lubrication and is ESPECIALLY BENEFICIAL WHEN USING HYDRAULIC LIFTERS!

They also increase oil scavenging for less internal drag and higher horsepower output. Oil pressure can be controlled by simply installing an oil pressure bleed-off system. Please check my other auctions.
