Two parts to it ...
1. hardware = new torque converter, new harmonic balancer, ring and pinon in the rear axle ...
2. software = new tune ...
Everything else still the same .... no changes to the frame that I can find so far. With that alone, Ram was able to do a new rating door tag .....
Hope that helps.
