Hi there Kevin!
The Lippert Trailer Axle Beam with Super Lube Spindles, part # LC74FP, uses a #42 spindle. For electric brakes and hub and drum assemblies, I recommend the 12" etrailer Electric Trailer Brakes, part # AKEBRK-6, paired with the Easy Grease Trailer Hub and Drum Assembly, part # AKHD-865-7-2-EZ-K.
The hub and drum assembly includes the bearings, races, and grease seal. The inner bearing is a 25580 with a 1.75" inner diameter, and the outer bearing is a 14125A with a 1.25" inner diameter. The included grease seal, GS2250DL, measures 2.25" inner diameter and 3.376" outer diameter.
Just make sure your wheels have an 8 on 6-1/2" bolt pattern to match these hubs. Do your wheels have that bolt pattern?
