Question:
Planning to do a disc brake conversion on our 2018 Montana 3791RD. TV is a 2017 Ram 3500 DRW and Cummins 6.7. Is the controller in the vehicle compatible with the hydraulic actuators in your kits?

Expert Reply:
On your 2018 Montana 3791 RD, with Dexter 7K axles, we do have the parts but not in a kit for axles that large.
I recommend the Kodiak Disc Brake Kit - 13" Hub/Rotor - 7,000 lbs # K2HR712D along with Bearing Kit # BK3-100. I recommend using grease # L11390 and cap # F001520 instead of doing the oil bath simply because if a seal fails you can melt your bearings and cause more issues than what grease would allow.
Then for the electrical aspects, I recommend the HydraStar Electric-Hydraulic Actuator w/ Line Kit for Disc Brakes - 1,600 psi # CAR-HBA16-2. The controller in your 2017 Ram 3500 DRW is not the best for these systems, so I recommend the Tekonsha Prodigy P3 # 90195 and wiring adapter # 3024-P.
Let me know if you have further questions. I've attached some articles to help further.
