How to Convert to Disc Brake Kit on 5th Wheel with 7K Tandem Axles


Hello. I have a 2021 5th wheel with tandem axles part number lc170-sbsa-92.5-74.5-NOSP-OS-L-8651-7227-18PT What parts would I need to convert it to hydraulic disc brakes?

Thank you for the info and the picture! I reached out to my contact at Lippert who confirmed that your axle uses a 25580 inner bearing, a 14125A outer bearing, and a 122088 grease seal - all of which can be found in the bearing kit # BK3-200.

This means for your 5th wheel trailer you will need the HydraStar Disc Brake Kit w/ Actuator for Tandem Axle Trailers # HSE7K-T1. The hub and rotors match up with your spindles and this comes with the actuator and hydraulic lines needed to get everything installed.
