Converting From Drum to Disc Brakes On a 2020 Grand Design Momentum with 7K Axles  

The exact replacement foot plate for the Level Up system you have is not available as a replacement. But you could use #LC314667. The issue is that it uses a smaller bolt than the Level Up foot. So you would have to use a 1/2 inch bolt that will…

The install of the Lippert Components High-Speed Power Stabilizer Jack #LC298707 that you referenced is not overly difficult. If you have basic mechanical skills and tools this wouldn't be a problem for you at all. I attached an install…

The part #HSE7K-T1SO comes with rotors that slip over idler hubs and the #HSE7K-T1 instead comes with rotors that are integrated into hubs. So it's totally different applications based on the style of hub that the trailer has.

Thanks for the picture of your axle sticker. From that I can tell that your 2017 Grand Design Momentum 376TH has 7k axles which is exactly what the HydraStar Disc brake kit part #HSE7K-TR1 was designed to fit so it would work great on your trailer…

The HydraStar Disc Brake Kit w/ Actuator for Triple Axle Trailers - 13" Rotor - 8 on 6-1/2 - 7K #HSE7K-TR1SO will work great on your 2020 Grand Design Momentum 376THS with 7k triple axles but this is a slip on kit so you will need idler hubs…

The Kodiak #K2R79 disc brake kit is designed to slip over an idler hub, not a hub drum. A 7K Dexter axle uses the 25580 inner bearing and a 14125A outer bearing with a 10-36 grease seal. To make that particular kit work, you'd need to remove…

I reached out to my contact at Kodiak and they advised me that the Kodiak Disc Brake Kit 7,000 lbs #K2HR712D takes ½” studs only. When you go to 9/16” studs, the 7k axle kit #K2HR79DS comes with an 8K hub that takes that only takes the…

The majority of 7000lb axles like the Dexter 7000lb axles you have on your 2020 Grand Design Momentum 351M use inner bearing #25580 and outer bearing #14125A but I recommend double checking this as there are still some odd bearing combination…

The TruRyde Electric Trailer Brake Kit #TRU96FR that you referenced is a pair of assemblies that include a left and right assembly. So if you need just a left and a right assembly ordering this part number would get you just that.

I was unable to identify your exact axle but I found Trailer Hub and Drum Assembly #AKHD-865-7-2-EZ-K to work if you have EZ Lube axles. If you do not have EZ Lube axles use Trailer Hub and Drum Assembly #AKHD-865-7-2-K. Both of these kits will come…

According to HydraStar, their #HSE7K-T1SO Disk Brake Kit with Actuator will take approximately 4-6 hours to install. This can vary according to how the trailer is equipped and how mechanically inclined the person completing the installation is. If…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.
