R&P Service Insight
A pre-greased hub drum helps reduce installation time during trailer service, but fitment still depends on matching the spindle, bearings, seal, brake size, and wheel bolt pattern before installation.
- Bearing Match: Uses the common L68149 inner bearing and L44649 outer bearing set found on many 3,500 lb trailer axle applications.
- Brake Match: Built for 10" x 2-1/4" electric brake compatibility.
- Wheel Match: Uses a 5 on 4.5" bolt pattern with five 1/2"-20 wheel studs.
R&P Knowledge Hub
Compatibility: This hub drum uses the industry-standard L68149 inner bearing and L44649 outer bearing combination commonly found on 3,500 lb trailer axles.
Vehicle / System Fit: Intended for utility, cargo, equipment, landscape, and boat trailer applications using compatible 3.5K axle, spindle, brake, and wheel specifications.
Installation Notes: Verify axle capacity, brake size, bearing numbers, seal dimensions, wheel bolt pattern, and spindle compatibility before ordering or installing.

Brand & Fitment Note
Selling Brand: R&P Carriages
Application Reference: Any axle or trailer application references in this listing describe compatibility, fitment target, or application style only where supported by verified dimensions, bearing numbers, seal style, brake size, and bolt pattern.
What This Means: This listing is for an R&P Carriages trailer hub drum kit, not a guaranteed OEM-branded item unless specifically stated and verified.
Before Ordering: Verify axle capacity, brake size, bearing numbers, seal dimensions, wheel bolt pattern, stud size, and included components before installation.
R&P Repair Insight
Hub drum fitment is commonly mistaken when only the axle capacity or wheel bolt pattern is checked. A correct match should confirm the bearing set, seal, brake drum size, stud size, and wheel pattern together.
- Bearing Check: Confirm your existing inner bearing is L68149 and outer bearing is L44649.
- Seal Check: Confirm the application uses a compatible 10-19 grease seal before installation.
- Brake & Pattern Check: Confirm 10" x 2-1/4" electric brake compatibility and 5 on 4.5" wheel bolt pattern.
