I bought oem 163 rails on the swap meet section from Polaris Pride at a good price and used all my stock wheels . I all so went with a stock track and did the F-bomb trick it works great and I saved tons of cash . When you go longer you need to tighten up your rear spring or go to the Z-bros spring kit . Instead of tunnel extension I tied up my rear flap so it does not get sucked up with the track and everything seems to be working . I have $ 575 in everything with springs from Z-bros . I even painted my rails black and they seem to be holding up, for kicks I painted the hyfax red and they are still holding up except for the bottom edge . With the $$$ I saved I purchased a fuel controller and a used slp pipe .
