Review on Extreme Max 5800.2009 - Gray Economy Snowmobile Dolly System: Efficient and Reliable by Ryan Turner

Owned for 5 years. After the first year of use on my sled, going in and out of the garage once or twice a week during the winter, they have completely fallen apart and are now only used as coasters. The wheel bearings are completely depressurized and water flows down the bolts that attach them to the racks and directly onto the balls in the bearings. The only way to keep them from rusting is to repackage the bearings periodically (for the price you could buy a whole new set) or store them in a low humidity location. (Good luck with this latest product which is intended for sleds that get hit with frozen water and when they get hot it melts on these coasters. There are MANY other sleds at Revain in the $50-60 range that last longer (I have another set for 3 years no problem) Do yourself a favor and spend money to get nice dolls.
