SOUTHWEST WHEEL 3,500 lb Trailer Axle Electric Brake Kit - Reliable

In this review of the SOUTHWEST WHEEL 3,500 lbs Trailer Axle Self-Adjusting Electric Brake Kit the bottom line is clear: it is a practical, well-built replacement brake kit for owners of utility and small travel trailers who want a complete, ready-to-install package. The kit stands out because it pairs self-adjusting backing plates with TruRyde hubs and drums that come with Genuine Timken bearings and seals, so the biggest reason to buy is the combination of factory-quality components and included hardware that reduces the chance of missing parts during installation.

Key Features

• Complete kit: Includes a pair of 10in x 2 1/4in TruRyde hubs and drums plus backing plates so installers get both the hub/drum and brake assembly in one purchase.
• Self-adjusting brakes: Self-adjusting TruRyde backing plates maintain proper shoe-to-drum clearance for more consistent braking without frequent manual adjustment.
• Quality bearings and seals: Comes with Genuine Timken bearings and seals to improve longevity and reduce the risk of premature bearing failure.
• Hardware included: Lug nuts, open and closed grease caps, cotter pins, spindle washers, spindle nuts and brake mounting washers and nuts are supplied to simplify installation.
• Wide axle compatibility: Designed to work with common trailer axle brands such as Al-Ko, Dexter, Lippert, and Quality Trailer Axles for easier fitment decisions.
• Manufacturing standard: TruRyde components are produced in an ISO/TS-16949 registered factory and hubs are chemically cleaned and painted black for corrosion resistance.

Who It's For

This brake kit is aimed at owners of utility trailers, travel trailers, horse trailers, motorcycle trailers, and similar 3,500 lb-class trailers who want a full replacement set with reliable components and minimal sourcing hassle. DIY mechanics who prefer a kit that includes bearings, seals and most of the required mounting hardware will find this especially convenient.

It is less suitable for users who need unusual spindle sizes or nonstandard bolt patterns; some customers reported axle size and castle nut compatibility issues, so those with uncommon spindles or who require exact castle nut fitment should verify spindle specs before purchase.
