They ate working well for me.

I give it 4 stars and not 5 because their description of the product is absolutely worthless so let me tell you what you're going to get. I ordered it blindly not knowing what sizes I would get but that I needed only 4 runners at 39" for my Otter Pro Small. I wasn't sure of the length but cross my fingers hoping it would work, and I needed them on 2 days. It did meet my needs. The box it came in says "201090 Hideout Hyfax". There are 5 runners, sizes 39", 36", 36", 36", 36". You do get a bag of harware to attach them to sled. You must have #3 size allen wrench fot the bolts, and 3/8 inch wrench for the nuts. Each connector set has 1" screw, smal washer, large washer and nylon lock nuts. I attached the 4 36" runners on my sled, they were 3 inches short on the back end which did not matter, it took about 30 minutes. I used a heat gun to warm up the part of the runner that curved up the front of the sled. I had 2 large trees at the bottom of a steep hill that were on the side of a frozen lake. After dropping them on the ice and cutting them up we made about 50 trips on the snowmobile with the sled attached behind. About 25 total miles. We would load the sled, run it a half mile down the frozen lake to a level place that we could get out. And then cross a paved street to our truck and load the wood into a truck, then when it got full we would drive the truck back the half mile up the street and unload it in the the backyard. On each trip the Otter sled was loaded with at least 100 lbs to 250 lbs of wood . The sled and the runners performed excellent on the fozen lake on the snow and ice. The runners saved my sled. On the snow and ice the runners showed no wear. The only wear came when we had to cross the paved road the runners got worn down....so dont drive them over paved or gravel roads. But for snow and ice...we beat the crap out of the sled and runners and they performed excellent. Had I not had them, my sled would have been destroyed in one trip. I will purchase these again when needed. Also the fact that they were 3 inches short on the back end made absolutely no difference, it was not enough to hurt anything.

I did not receive what I expected! I have a older Otter sled with worn out runners that need to be replaced.They sell these by the name of sled,and yes my sleds name is outdated. How hard would it be to give the length in description!!!!!!
