We were checking out the same options only for a track upgrade for our 2014' PRO 163". Called a shop and they were saying in the range of $950 for a Camso Challenger Extreme. Polaris website has the 163" Series "6" track @ $$1585.99!! Even with discounts, it's a lot of dough! We have a 2016' 155" Axys with no track issues on the factory Series "6" so I am not concerned other than with price!
Just putting a question out there with which Challlenger Extreme 2.5 track were people running? The "Full cup Deep V" lug or the "Saw tooth" lug? We are thinking going with the full cup lug that looks similar to the factory 2.6 lug.
