Multiquip EE46802 MQ Trailer Spring Axle

The Multiquip EE46802 MQ Trailer Spring Axle is a genuine OEM component designed for the TRLR45US1 water trailer with hydraulic brakes and a 4-inch drop configuration. As a direct OEM replacement, this axle is built to the original design specifications for the TRLR45US1, ensuring a correct, consistent installation without guesswork. DHS Equipment supplies this part straight from the Multiquip OEM supply chain, so you can be confident you are receiving an authentic component for your trailer.

Key Features

• OEM-Grade Structural Integrity — Engineered to the original load-bearing and torsional specifications required of a trailer axle, not a general-purpose substitute.
• Hydraulic Brake Compatible — Designed specifically for hydraulic surge brake systems, ensuring proper brake engagement geometry and consistent stopping performance.
• 4-Inch Drop Configuration — The correct 4-inch drop spec matches the TRLR45US1 frame height, keeping ride height, tongue angle, and load distribution within design parameters.
• Direct Fitment for TRLR45US1 — Verified for Multiquip TRLR45US1 water trailers; mounts to the existing frame without alteration to suspension mounting points.
• Critical Safety Component — A worn or failed axle on a loaded water trailer compromises towing stability and brake response; replacing with a genuine OEM unit restores safe, rated towing operation.

The spring axle is the structural backbone of the trailer's suspension and brake system. It supports the trailer's loaded weight, absorbs road shock through its leaf spring mounting, and provides the mounting interface for the wheel hubs and hydraulic brake assemblies. A damaged, bent, or worn axle can cause uneven tire wear, compromised brake performance, and dangerous trailer sway under tow — making timely replacement with a correctly spec'd OEM unit essential for safe operation.
