It's a great charity event. My wife was working with the Protection 4 Paws people up there. I was at home with our dogs. Even for a messed up year they had an outstanding turn out for sponsors this year.

Absolutely. All of the control arms will carry over, including the pro x cradle on the rear axle, the spring seats will carry over, front track bar.
