are viper products any good.. looking to purchase a rack extender and winch.. what size winch should i get for a 900 lb quad?

 

I don't know if Viper is good or bad. I here both about their winches. You should get <u>at least</u> a 2,500 pound winch, but 3,000 pound would be even better. If you get one that's rated 3 times higher than the the weight of the quad, it will pull it out of deep mud and other crap without having to use a ****** block to double the pull.
