Hydrastar Disc Brake Kit For a 2018 Grand Design Momentum Triple Axle Toy Hauler With 7,000LB Axles

Question:

Possible interest in a 7000lb triple axle disc brake conversion. I noticed you offer hub and disc kits and slip on my hub disc kits. With th later, are longer wheel studs required. Thx

I reached out to Hydrastar and they are very familiar with disc brakes on your 2018 Grand Design Momentum toy hauler. They said Grand Design typically gets their axles with 9/16" studs of which we only have the Hydrastar Disc Brake Kit w/ Actuator for Triple Axle Trailers # HYD54FR you found. These have the integral hub/rotor selection and we do not have any slip on options for the 9/16" studs. The studs which come on these hubs are going to be long enough for your factory wheels.
