Multiquip EE46667 Axle Spring MQ Electric Brake 4" DR

The Multiquip EE46667 Axle Spring MQ TRLR45US1 Electric Brake 4" DR is a genuine OEM replacement component designed for the TRLR45US1 trailer. As a direct OEM part, EE46667 is manufactured to the same specifications as the original, ensuring a correct fit without modification. This part is confirmed to fit the TRLR45US1 trailer platform, making it the dependable choice when restoring your trailer's axle and braking system to proper working order.

Key Features

• Genuine OEM Construction — Engineered to the same load-bearing and spring-rate specifications as the original axle assembly, ensuring structural integrity under towing stress.
• Direct-Fit Replacement — Designed to bolt directly into the TRLR45US1 trailer frame using the original mounting points, streamlining the replacement process.
• Confirmed TRLR45US1 Fitment — Verified compatibility with the Multiquip TRLR45US1 trailer, eliminating guesswork when sourcing a replacement axle.
• Integrated Electric Brake Compatibility — Built to work in conjunction with the trailer's electric brake system, maintaining proper brake engagement and stopping performance.
• Restored Load Stability — A worn or damaged trailer axle can cause uneven load distribution and handling issues; replacing it with this part restores balanced, stable towing.
• Electrical Brake Safety — Correct axle geometry is critical for electric brake alignment; using the proper OEM component helps ensure the brake actuators engage as intended during towing operations.

The spring axle on a trailer is the structural shaft that supports the trailer's weight and load while allowing the suspension to flex and absorb road shock. On the TRLR45US1, this axle is paired with an electric brake system, meaning the axle must maintain precise alignment so the brake drums and electric actuators can engage correctly. When an axle is bent, worn, or structurally compromised, it can lead to uneven tire wear, poor handling, and degraded braking performance — all of which create safety risks during transport. Replacing a damaged axle with the correct OEM component restores the trailer's designed load capacity and keeps the braking system operating as intended.
