This seal is a great idea. Shame Polaris didn’t think of it. Thanks saved me $2,500.00 fixing it myself vs dealership

PRODUCT REVIEW

Awesome product. Install was very easy and straight forward. Product arrived fast and of good quality. Installed on my 19 defender xmr and so far after a few rides at the mud park I see no leaks.

PRODUCT REVIEW

This was some of the best customer service I've ever received from a company. I bought this as a last minute upgrade for a trip i was taking in a week. I emailed them after ordering to see if my order could be overnighted to ensure id be able to install in time. I received a response almost immediately and let's just say my order was sitting at my door step the next day. Looking forward to seeing this thing in action on the Drummond Island mud and rocks!

PRODUCT REVIEW

Install was easy, several hundred miles on repair now. Everything still looks good. Original seal was damaged from a belt failure. I would recommend this seal and would use it again if needed.

PRODUCT REVIEW

Once i gathered all the tools necessary to remove the clutch, and the old seal, the process was straight forward. I have been on several long rides with no issues. I would recommend the WKP seal to anyone experiencing a crank seal leak
