Determining Correct Axle Upgrade For 2018 Grand Design Imagine Travel Trailer
Question:
I would be happy to make a recommendation for upgraded axles and suspension components for your 2018 Grand Design Imagine 2670MK, but first I will need a few measurements from your current components. Starting with the axle you will need to measure your current axles from hub face to hub face and from spring center to spring center to determine the correct length the replacement axle would need to be. For example the Dexter Trailer Axle Beam with E-Z Lube Spindles - 89" Long - 5,200 lbs # 8327820 measures 89" from hub face to hub face, and 74" from spring center to spring center as shown in the included diagram. This axle has a 5200lb weight capacity, but keep in mind that replacing your axles will not increase the GVWR of your trailer, as you are limited to the lowest rated component which would then be the trailer's frame. The correct disc brake kit will be dependent on the axle you choose. The # 8327820 would use Dexter Trailer Idler Hub Assembly for 5,200-lb E-Z Lube Axles - 6 on 5-1/2 # 8-213-5UC1-EZ and Kodiak Disc Brake Kit - 12" Rotor - 6 on 5-1/2 - Dacromet and KodaGuard - 5,200 to 6,000 lbs # K2R526DKG. You would also need Brake Lines # HydraStar Hydraulic Brake Line Kit # HS496-252, Electric Over Hydraulic Actuator # HBA16, Breakaway Kit # 20400, and a trailer brake controller that is compatible with electric over hydraulic brakes like the # 90195. If you can provide the measurements of your current axle, I would be happy to recommend the correct replacement and confirm the suspension components compatible with that axle. I included videos for each of the products mentioned, and a link to a helpful article that goes over adding electric over hydraulic disc brakes for you to take a look at.
