Question:
I am currently in the process of purchasing a Grand Design Momentum 398MR triple axle trailer. It currently has 7,000lb axles. I would like to add independent suspension to it and upgrade the axles to 9,000lbs with oil bathed bearings, plus I want to add disc brakes. Do you have anything the will work? The frame is 12 I beam.

Expert Reply:
I have some great options for you to upgrade the Grand Design Momentum 398M such as the Roadmaster Comfort Ride Leaf Spring Suspension Kit part # RM-2460-2570-3 which will help drastically increase ride quality/performance and the HydraStar Disc Brake Kit w/ Actuator for Triple Axle Trailers part # HSE7K-TR1 which will increase stopping power. They can be converted to oil bath with the Kodiak XL ProLube Oil Bath Hub Body and Cap part # XLPROLUBE2440 and Oil Seal part # 9103309.
Unfortunately, the axle-less system you're referring to doesn't go up as higher as you would need.
