Southwest Wheel 3,500 lb Trailer Axle Self Adjusting Electric Brake

In this review the Southwest Wheel 3,500 lb self-adjusting electric brake kit is evaluated for utility trailers, travel trailers and similar tow rigs. The bottom line: this kit is for owners who need a complete, ready-to-install 10' self-adjusting brake assembly with matching TruRyde hubs and drums and all necessary hardware, and the single biggest reason to buy is the comprehensive parts package that replaces a full axle end with bearings, seals, nuts and caps included. It saves time and reduces parts hunting when swapping or upgrading brake ends.

Key Features

• Complete kit: Includes a pair of 10' x 2 1/4' self-adjusting brakes, backing plates, and 5-4.5' bolt circle TruRyde hubs and drums so installers receive everything needed for a full axle-end replacement.
• TruRyde manufacturing: Parts are produced in an ISO/TS-16949 registered factory, offering automotive-standard build quality for long-term reliability on the road.
• Full hardware set: Bearings, seals, lug nuts, open and closed grease caps, cotter pins, spindle washers and nuts, and brake mounting washers and nuts are included to simplify installation and ensure compatibility.
• Wide axle compatibility: Designed to work with Al-Ko, Dexter, Lippert, and Quality Trailer axles, making it a versatile option for many common 3,500 lb trailer setups.
• Durable finishes: All studs are 1/2'-20 with yellow zinc plating and hubs are chemically cleaned and painted black in an electrostatic booth for corrosion resistance.
• Tested components: SAE rated friction material, magnets tested for pull force, and QAI certification provide confidence in braking performance.

Who It's For

The kit suits trailer owners who need a direct, full replacement for 3,500 lb axle ends and want a mostly plug-and-play solution with bearings and hardware included. It is especially useful for DIY mechanics and small shops replacing both brakes and hub/drum assemblies at once, and for those fitting to Dexter 3500 lb style axles where customers reported a precise fit.

Those who should look elsewhere include owners of axles with nonstandard spindle lengths or bolt patterns other than 5-4.5' bolt circle, and users needing a different flange configuration than the 4-hole brake flange for 84 spindles specified in this kit.
