I know a tether kill switch is a must in racing ,but which one is the best? PRO Design or the one Tusk
off-road has??

 

i use the pro design one, its works great for me and they got a bunch of colors.

 

Pro Design here also. Never had a problem.

 

pro design on both my race quads and no problems

 

I too have Pro Design, so far Im very happy with it............

 

id say about any of them will work, personal preference what style you want to use. i have the pure polaris one on my predator and like it, a friend has a pro design on his honda so far neither of us have had any troubles with them and the one time i used mine it was nice not to have to chase down my quad.

 

I currently own 3 pro-designs and have had 4 other PD's in the past. Never had a problem.
