Electric Trailer Brake Assemblies for 3,500 lb Axles

This pair of 10 inch by 2-1/4 inch electric trailer brake assemblies delivers left and right side stopping power for 3,500 lb axle setups.

Overview

These electric trailer brake assemblies are a matched left and right pair sized for 3,500 lb axles, giving you complete drum brake replacement in one box. Each electric trailer brake assembly engages when the tow vehicle sends current through the magnet, pressing the shoes against the drum to slow the trailer. They suit boat, utility, cargo, and equipment trailer owners who maintain their own brake systems.

Specs At A Glance

Good To Know

Q: Do I need a brake controller to run these? A: Yes, electric trailer brakes require a brake controller in the tow vehicle to send current to the magnets. The controller lets you adjust braking effort to match the load.

Q: Can I install these on my own? A: They bolt to the brake flange on the axle and connect to the trailer wiring, which most DIY owners can handle with basic hand tools. Check that your spindle and hub match the 10 inch by 2-1/4 inch size before starting.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
