Gear ratio means everything gear it to the same as a prowler mtn. Cat I just put a track and rear suspension off of a 2000 Powder Special 136"x2" on a '91 Prowler mtn. And it runs good and feels strong! I don't remember what the primary weights are but it has a yellow /green spring the other Prowler I have has a red spring primary both are cat springs. Secondary is 48/44° helix yellow spring. A 52/44° helix maybe an option but it works best on the 600s.
Gear ratio is 18/40T
