Made this out of aluminum for lightness. The A-arms are from a 96 Arctic Cat ZRT. I had to make my own blukhead. It was tuff to get the geometry down for the travel of the A-arms. I use it going to my cabin. I was tired of breaking stuff while using my flat bottom sleds (otter and a home made UHMW freight sled). I to designed it to haul two coolers and three 5 gallon gas jugs. The front box can hold small 1 to 1 and a half gallon gas jugs or just extra gear. Im going to put wider ski's on next year.
I haven't broke one bottle or can of beer. Can go up to 40 to 35 MPH over stutter bumps.
