The Kodiak Disc Brake Kit # K2HR8D11E58 is designed to fit 8,000 lb axles with a 4-bolt brake flange. Although the bearings will fit, your 2020 Grand Design Momentum 397TH has 7k axles with a 5-bolt brake flange so you will want a different disc brake kit. I recommend verifying this information to be sure.

Since you have a triple axle trailer, I recommend the Hydrastar Disc Brake Kit w/ Actuator for Triple Axle Trailers # HYD54FR. This comes with the disc brakes, the brake lines, and the Hydrastar electric over hydraulic brake actuator. Grease caps are sold separately. The only other thing you might need if you don't already have one is a breakaway like the # 50-85-313.

Since you currently have electric brakes you should already have a brake controller. If it is a factory brake controller it is possible you will need the # HBA-CAM for it to work properly. This depends entirely on the vehicle. If you have an aftermarket brake controller you want to make sure it is compatible with electric over hydraulic.
