Your best bet is contact Top Kart USA for information on what nerf bars and bodywork works best for the Viper chassis. It looks like Huggler Racing is in your state, and may also be able to help you find what you are looking for.
There you have it partner, look no more. I found them for you.
These puppies will work for any 99 to 2002 chassis, but with a little bit of engineering you may be able to install new style plastics on them, if you don’t wanna run the old bread box style. It’s not that hard at all.
Thank you I appreciate the help! This is my first kart so I’m stumbling through a few things. Going to do a lot of reading – this is a great site with lots of info.
