I am cleaning out my closet and getting rid of all the good parts Sterling sends back when they freshen up my motors. I can not gaurentee make or actual size of any of them as Sterlings invoices do not have make, part number or size of anything. Just a price.
I know he uses the best and i know they are expensive. These parts have less then 15 hours on them.

I have 2 sets of these I am accepting offers. I'll leave them up for a week and the high offer will get them.

Springs make PSI Part Number SPI

If i have something listed incorrectly please feel free to let me know so i can change it.
