We have just announced and started shipping CVA driveshaft sets for the 22-4. The team has been testing these for quite a while, and the results have been VERY positive. Ryan Maifield, Dustin Evans, and Dakotah Phend have all been using these on their summer victory tour.
A CVA joint will create more natural lock up or "bind" than a universal joint. This helps to stiffen the suspension when under acceleration, which makes the car flatter and drive off harder. It also helps jump landings, when you apply some throttle (especially when you know you are casing/flat landing).
Along with going to the "shorty" setup on the 22-4, the CVA's were the other huge setup change the team has made that has resulted in many wins this summer. Try them out today!
