Overview
This R&P Carriages one-axle service kit is built for trailer owners repairing or refreshing a compatible 8-lug electric brake axle.

R&P Knowledge Hub
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.
Verify all measurements, axle rating, spindle style, bearing numbers, seal size, brake flange mounting, wheel bolt pattern, and included components before installation. This kit does not include the axle tube, springs, suspension components, or unrelated axle structure. Axle and fitment references describe application compatibility only.
Complete One-Axle Brake Refresh
Includes the major drum, hub, bearing, seal, brake shoe, magnet, spring, hardware, and backing plate components listed for one compatible trailer axle.
12" x 2" Electric Brake Setup
Designed around 12" x 2" electric trailer brake assemblies for compatible 5,200 lb, 6,000 lb, and 7,000 lb axle applications.
8-Lug Drum & Hub Assemblies
Kit includes two brake drum and hub assemblies for 8-bolt wheel applications where the spindle, bearings, seals, and brake size match.
Shop-Friendly Service Solution
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.
