945475 3.5K 5 on 4.75 Brake Drum Family

Trailer Hub & Brake Drum Kit — 10" x 2-1/4" — 5 on 4-3/4"

Complete one-location trailer hub and brake drum service kit for common 3,500 lb #84 spindle applications using 10" x 2-1/4" electric brakes and the 5 on 4-3/4" small GM-style bolt pattern.

Part Number: 945475-1-KIT 10" x 2-1/4" Brake Size 5 on 4-3/4" Bolt Pattern

Overview

This R&P Carriages hub and brake drum kit is built for service replacement on compatible 3,500 lb trailer axle applications where the brake size, bearing numbers, seal size, spindle style, and wheel bolt pattern match. It includes the hub/drum assembly with bearing races installed, plus common bearing, seal, dust cap, and lug nut service parts for one hub/drum location.

R&P Service Insight

Brake drum fitment depends on more than axle weight alone. Match the brake size, spindle, bearings, seal, and wheel bolt pattern before ordering.

Brake Size: Use only where a 10" x 2-1/4" hub/drum is the correct match.
Spindle Match: Intended for common #84 spindle-style 3,500 lb axle service applications where bearing and seal dimensions match.
Bolt Pattern: 5 on 4-3/4" is not the same as 5 on 4-1/2". Confirm before installation.

R&P Knowledge Hub

Compatibility: Fits common Dexter/AL-KO-style 3.5K #84 spindle applications where the listed brake size, bearings, seal, and bolt pattern match. Verify before ordering.

Vehicle / System Fit: Common trailer axle service application using 10" x 2-1/4" electric brakes and a 5 on 4-3/4" wheel bolt pattern.

Installation Notes: Confirm inner bearing L68149, outer bearing L44649, 10-19 style seal fit, wheel bolt pattern, brake size, and spindle dimensions before installation.

Performance Insight: Bearing races are already installed in the hub/drum assembly, helping reduce service setup time when the included bearing and seal set matches the trailer.

Brand & Fitment Note

Selling Brand: R&P Carriages

Application Reference: Dexter and AL-KO names are used only to describe common application style and fitment reference where dimensions and configuration match.

What This Means: This listing is for an R&P Carriages curated trailer hub and brake drum service kit, not a guaranteed OEM-branded item unless specifically stated and verified.

Before Ordering: Verify brake size, bolt pattern, bearing numbers, seal inside diameter, spindle type, axle rating, and included components before installation.

R&P Repair Insight

This hub/drum family is a strong service option when the trailer uses the 5 on 4-3/4" small GM-style pattern, but mismatching the bolt pattern or seal size can stop the repair quickly.

Seal Check: This kit uses a 10-19 style seal. Verify 1.719" / 1.72" seal ID before ordering.
Bearing Check: Confirm L68149 inner bearing and L44649 outer bearing numbers against the existing hub or spindle.
Wheel Check: Confirm the wheel is drilled for 5 on 4-3/4", not the more common 5 on 4-1/2" pattern.
