R&P Service Insight
This kit is intended to make a four-wheel brake and hub/drum service more straightforward by bundling the major wheel-end components for the matching D80N narrow axle setup.
- Before Ordering: Verify the existing hub/drum reference, bearing numbers, seal size, brake size, bolt pattern, and stud size.
- Side Matching: The kit includes two side 1 and two side 2 brake assemblies to service four wheel ends.
- Wheel-End Service: Inspect spindles, wiring, magnets, mounting hardware, and related components during installation.
R&P Knowledge Hub
Compatibility: Designed for 7.2K-8K narrow brake axle applications using the listed hub/drum, bearing, seal, bolt pattern, stud size, and brake size combination.
Vehicle / System Fit: Trailer axle brake and hub/drum service package for D80N narrow-style applications where measurements and part references match.
Installation Notes: Confirm bearing numbers, seal dimensions, bolt pattern, wheel stud size, brake assembly size, and brake flange/mounting compatibility before installation.
Performance Insight: Narrow D80N brake setups should not be treated as the same as standard-width 8K brake setups. Match the complete hub/drum and brake configuration before ordering.
Brand & Fitment Note
Selling Brand: Unbranded
Application Reference: Dexter D80N, 8-393, 7.2K-8K, 8 on 6.5", 5/8" studs, 12-1/4" x 2-1/2" brakes, 25580 inner bearing, 2475 outer bearing, and 2.25" x 3.38" oil seal references are used for fitment identification.
What This Means: This listing is for an unbranded brake and hub drum kit, not a guaranteed OEM-branded item.
Before Ordering: Verify your axle, hub/drum number, brake size, bearing numbers, seal size, bolt pattern, stud size, and narrow D80N application before installation.
R&P Repair Insight
The most important fitment check on this package is confirming that the trailer uses the narrow D80N configuration. Standard-width 12-1/4" brake applications may look similar but should not be assumed interchangeable.
- Check the Hub/Drum: Confirm 8-393 style reference and 8 on 6.5" bolt pattern.
- Check the Studs: Confirm 5/8" wheel studs and matching 5/8"-18 lug nut requirement.
- Check the Brakes: Confirm 12-1/4" x 2-1/2" self-adjusting electric brake compatibility for your axle setup.
