FAS PREDATOR LOWER PULLEY (No tune Required) Ram TRX, Hellcat Durango, Trackhawk & Hellcat

Definitely see a jump in performance! Highly recommend

Delivers as promised.

Straight forward install. I was a little offput by the flywheel plate removal at first, not realizing that was part of the install procedure, but the directions worked. Seat-of-my-pants dyno definitely says there is more get-up-and-go. I'm having to restrain my right foot more, as I'm chirping the tires in turns far easier than I was before. They are not kidding when they say this is the best bang-for-your-buck, easy modification.
