Polaris XP Pinion Seal Front Gearcase November 25, 2015 Here is the number for the seal I used a year or so ago to fix mine. It has been working like a charm on my 550XP. This way you won’t have to buy the whole kit from POPO. SKF 9696 25X32X7 Ronnie Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
