Aeagle 5-on-4.5 in Bolt Circle Trailer Drum Kit — Twin 10x2-1/4in Self-Adjusting Electric Brakes for 3,500 lb Axles

This kit supplies the core hardware needed to convert or replace brake drums on standard-lube 3,500 lb trailer axles that accept L68149 inner and L44649 outer cone bearings and a 4" brake flange PCD. Built from gray cast iron with a corrosion-resistant finish, the drums are designed to work with Dexter, Al-Ko, Lippert, Quality and other compatible axle brands. The package includes hubs, bearings, seals, and both left and right electromagnetic self-adjusting brakes so you get a matched set ready for installation on appropriate spindles.

Will these drums fit my trailer axle and spindle?

These drums are engineered for 3,500 lb axles that use L68149 inner cones and L44649 outer cones and fit spindles sized between 1-1/16" and 1-3/8". They mount to a 5 on 4.5" bolt pattern with a 4" brake flange PCD. They do not fit 4,400 lb axles, Nev-R-Lube axles, or certain Airstream Classic trailers built after July 2005.

• Compatible bearings: inner L68149, outer L44649
• Spindle diameter range: 1-1/16" to 1-3/8"
• Bolt circle: 5 on 4.5" with 4" brake flange PCD
• Not compatible: 4,400 lb axles, Nev-R-Lube, Airstream Classic (post-7/2005)

What comes in the Aeagle 5-on-4.5" drum kit?

The kit is sold as a twin set and includes the hardware required to replace both sides of an axle: two drums, bearing cones, seals, dust covers, fasteners, and one left plus one right self-adjusting electric brake assembly. That makes it a comprehensive swap for standard-lube axles when you're replacing worn drums and brakes together.

• 2x brake drums (5 on 4.5" bolt circle)
• 2x inner cone bearings (L68149), 2x outer cone bearings (L44649)
• 2x oil seals, 2x dust covers, 2x rubber plug dust covers
• 10x wheel hub nuts, assorted washers, spring washers, nuts, hex slotted nuts, split pins
• 2x electromagnetic self-adjusting brakes (left and right)

How durable and reliable are these brakes and drums?

Aeagle manufactures the drums from gray cast iron and applies a rust-resistant coating to extend service life. The electric brakes are self-adjusting and designed to keep consistent shoe-to-drum contact under normal trailer use. Each kit is tested before shipping and covered by a 12-month warranty for manufacturing defects.

• Cast iron drum with protective finish for corrosion resistance
• Electromagnetic self-adjusting brakes for maintained performance
• Pre-shipment testing and 12-month limited warranty

What should I check before ordering and installing?

Confirm your axle is a standard-lube 3,500 lb type and verify the inner and outer bearing part numbers and spindle size. Check the brake flange bolt circle and ensure your hub hardware matches the 5 on 4.5" pattern. If your axle uses factory hub lube systems like Nev-R-Lube or is rated 4,400 lb, this kit will not be compatible.

• Verify axle rating: 3,500 lb standard-lube only
• Confirm bearing numbers: L68149 inner, L44649 outer
• Measure spindle diameter and bolt-circle pattern
• Have correct tools and torque specs for hub installation
