Are there any adapters or anything that can make the Ranceher into an indepent rear suspension machine?? Any input welcome

 

Interesting post. Polaris only puts this on their sportsman line of quads, but this also adds additional weight. Arctic cat & some Kawasaki's have a semi-IRS arrangement.

You might be able to fabricate a semi-IRS arrangement. To take the Rancher to a full IRS would take refitting the rear end completely.
