Will 7,000lb HydraStar Disc Brake Conversion Kit Fit a 2021 Jayco Eagle 321RSTS W/ 6,000lb Axles?  

Updated 10/11/2021 | Published 10/10/2021



Question:

I have a 2021 Jayco Eagle 321RSTS want to upgrade to disk brakes. But this has 6000lb axels. Will this HSE7K-T1 kit work? I dont see that you carry the HSE6K-T1. Axle tag attached.

I would be happy to help!

First things first 5,200 - 7,000lb axles are all compatible with the same hubs so you can use the HydraStar Disc Brake Kit w/ Actuator for Tandem Axle Trailers - 13" Hub/Rotor - 8 on 6-1/2 - 7K # HSE7K-T1 on your 2021 Jayco Eagle 321RSTS. I see you mentioned an HSE6K-T1 kit but HydraStar does not offer such a kit.

The brake pads used are a bit different as they are designed for heavier trailers but they will still be OK. The biggest thing you need to check is that this kit is designed for wheels with the 8 on 6-1/2" bolt pattern.

If your wheels use the 6 on 5-1/2" bolt pattern you will need to go with a different disc brake kit. You will need two of the Kodiak Disc Brake Kit # K2HR526DKG, two bearing kits # DBRKHW6EZ, brake line kit # HS496-252, and EOH actuator # HS381-8067 instead.

With either kit you will need to have a trailer brake controller that is compatible with electric over hydraulic brakes. If your controller is not then I recommend replacing it with the Tekonsha Prodigy P3 # 90195 as it is the most reliable controller that is compatible with EOH brakes.

I included a few videos of the products mentioned for you to take a look at.
