RALZAOTO Electric Trailer Brake Magnet Kit 12-1/4" for 9,000–10,000 lb Axles — Includes Springs & Retainers

RALZAOTO 12-1/4" Electric Trailer Brake Magnet Kit provides direct-fit replacement magnets, springs, and retainers engineered for 9,000–10,000 lb axles to restore reliable electric braking response.

If your trailer brakes are slow to engage or failing inspection, replacing worn brake magnets is one of the most effective repairs. This kit is sized for 12-1/4" x 3-3/8" or 12-1/4" x 4" electric brake assemblies and is compatible with many common axle brands including Dexter, Rockwell, Al-Ko, and Lippert. Each kit steps you through a quick swap with all the essential hardware included so you can get back on the road without searching for separate components.

How will this magnet kit improve my trailer's braking performance?

Worn or glazed brake magnets can delay magnetic field buildup and reduce braking torque. Replacing the magnets restores consistent electromagnetic force, improving how quickly and evenly brakes apply under electrical command. The included coil springs and retainer clips also ensure proper alignment and return action for reliable operation.

• Restores correct magnetic pull for prompt brake engagement
• Includes springs and clips to secure magnets and ensure correct clearance
• Precision fit reduces wobble and uneven wear on brake shoes

Will this kit fit my axle and brake assembly?

This kit is designed specifically for 12-1/4" electric brake assemblies with shoe dimensions for 3-3/8" or 4" widths and is suitable for axle ratings from 9,000 to 10,000 lbs. It matches common OEM magnet sizes used by major manufacturers, so it’s a direct replacement in most late-model trailers. Always compare your existing magnet dimensions and mounting style before purchase to confirm fitment.

• Fits 12-1/4" x 3-3/8" and 12-1/4" x 4" brake assemblies
• Compatible with 9,000–10,000 lb axle ratings
• Designed to replace magnets from Dexter, Rockwell, Al-Ko, Lippert and similar brands

What comes in the package and how hard is installation?

The kit includes two brake magnets with attached wiring, two coil return springs, and two retainer clips — everything needed to replace both magnets on a single axle. Installation is straightforward for anyone comfortable with basic trailer brake disassembly: remove the drum, unbolt the old magnets, transfer wiring, and secure the new pieces. Torque and clearance checks are recommended during reassembly.

• 2x magnets with wire for direct wiring swap
• 2x coil return springs and 2x retainer clips for secure mounting
• Simple steps: remove drum, replace magnets, verify clearance and wiring
