Question:
I’m considering upgrading the electric drum brakes on my 2022 Prime Time Crusader 335RLP to disc but am unsure what parts are needed. Do you sell a kit that includes everything I need or is it more of a part by part deal?

Hello Clair,
Looking to make the swap to disc, always a great idea!
I see that you were able to place an order already. Since you have a tandem set-up with each axle rated for 6K, going with the Hydrastar Disc Brake Kit w/ Actuator for Tandem Axle Trailers - 12" Rotor - 6 on 5-1/2 - 6K # HYD74VR is a fantastic choice.
Adding the Kodiak Hydraulic Brake Hose - 1/8" ID - DOT Approved - 3/16" Male Fittings - 4' # KD47FR, T-fitting # DE54SR, and 90 degree fitting # DE94SR will ensure you have what you need to make the swap.
The only question I have, is what kind of brake controller are you using? I just want to make sure that you have the EOH (electric over hydraulic) setting that is needed to control these brakes.

I have a 2013 F250 with the factory installed brake controller, I didn’t realize that there was a difference in controllers between electric and EOH. Is that going to be a problem or will it be OK to use?
