Compatibility: Listed for compatible 5,200 lb, 6,000 lb, and 7,000 lb trailer axles using 12" x 2" brakes, 8-bolt wheels, and #42 spindle dimensions.
Vehicle / System Fit: Trailer electric brake axles, including compatible torsion and leaf spring axle setups where all measurements and mounting points match.
Installation Notes: Verify brake size, wheel bolt pattern, spindle type, inner and outer bearing numbers, seal size, brake flange mounting, and axle rating before ordering or installing.
Performance Insight: Refreshing the drum, bearings, seals, brake shoes, magnets, springs, and backing plate assembly together helps correct multiple wear points in one service job.
Includes the major drum, hub, bearing, seal, brake shoe, magnet, spring, hardware, and backing plate components listed for one compatible trailer axle.
Designed around 12" x 2" electric trailer brake assemblies for compatible 5,200 lb, 6,000 lb, and 7,000 lb axle applications.
Kit includes two brake drum and hub assemblies for 8-bolt wheel applications where the spindle, bearings, seals, and brake size match.
Useful when worn bearings, grooved drums, weak magnets, or tired brake hardware make a full assembly refresh more practical than replacing one small part at a time.
