I have some mattracks for sale
They are the M3-UR....which are the wider version and are rated for gross vehicle weight of 3500 pounds. "Gross weight is vehicle weight minus wheels and tires" My sammy has a full exo cage and is a hard top and is 2950 pounds. So sammys are good on weight....not sure about sidekicks and trackers.

Good condition....about 25 hours of use on them. Cost between 7500, plus the suzuki adapter kit which is 1500, so 9000. I have the adapter kit for the suzuki and the ones for a kobota 1100 utv.

PM me if interested with you number if you are interested. Item located in washington, but they are easy to ship with a freight company for around 400-500.

Asking 6500 or best resonable offer.
