I have an Orange EPI Primary spring for sale. This is the spring that comes in the EPI clutch kit for the 550 Sportsman. It can be used in any Polaris Primary. I had it in my 550 Sportsman and it worked very well. I have returned that 550 to stock and sold it. I no longer have a use for this spring.
This spring will give you a harder launch and stronger bottom end power. I was able to wheelie very easy with this spring and the clutching felt much sportier. If you are an easy trail rider who could care less for performance then this is not for you. If you like to play in the mud, spin your tires and pull wheelies then this is for you.
Asking 20 shipped anywhere. Your welcome to pick up if you like. Item located in Ramey PA
