You looking for transmission here it is! I just wanted let my customers know we are Dealer for Randys Transmission. I wanted share this info from Randy himself an his staff.
We have been seeing a lot of people asking recently if we do the Aisin (AS69RC) transmission.
Of course we do! What do you think holds that 1000hp behind the 15? Duct tape and the Lord’s Prayer? 😂
We have two solutions for those of you with the high output Cummins for the 13-18 Ram 3500 4500 & 5500’s Stage 1: rated at 600HP and 1000HP for stage 2

19+ are still in R&D at the moment - but will be finalized soon enough.
