Question:
Trying to find the correct electric brake assemblies for my 2025 Keystone Hideout 220BH. Not seeing one on the web side? Am I missing something? Here are the Axle Details from the tag: Terran axle ST52B-C-S-85-68.5-US-6107-7112-E CUSTOMER REFRER. CODE: A021 CUST. PART 5.1K 85/68.5 BRAKE 655 MFG DATE 2/21/2024 Capacity 5100 LBS SERIAL B2451A003913,5100

Hey Matt! That axle has a 5-bolt brake flange and uses 12" brake assemblies. For a replacement you can use the Terran Axle Electric Trailer Brakes # TX77ZJ you were looking at. They are listed for a higher rated axle but will work with your 5,100 lb axle as well.
Any big trips coming up with your Keystone Hideout this fall?
