Complete 3,500 lb electric brake axle build kit designed for use with standard 2" Schedule 40 steel pipe (2.375" OD, 2.04" ID). Kit includes pre-welded EZ Lube spindles with brake flanges aligned and square, 10" electric brake assemblies, hub drums, bearings, seals, hardware, and spring perches. Axle tube or pipe is not included.
3,500 lb trailer axles commonly use 10" x 2" electric brake assemblies paired with L68149 inner and L44649 outer bearings. EZ Lube spindles incorporate an internal grease passage to simplify maintenance.
Proper brake flange alignment and spindle squareness are essential for even braking and hub rotation. Spring perch placement must match the trailer’s leaf spring spacing. Confirm bolt pattern, bearing sizes, hub face dimension, and spring centers prior to welding.
