Key Features
- OEM Spring and Load Rating — manufactured to the original spring rate specification for the TRLR45US1, ensuring the axle carries the rated load without deflection or premature fatigue.
- Electric Brake Compatible — designed specifically for the TRLR45US1 electric brake configuration, with the correct mounting geometry for brake hardware to seat and function properly.
- Direct-Fit for TRLR45US1 — bolt-pattern, hub spacing, and suspension mounting points match the original axle on TRLR45US1 trailers exactly.
- Structural Integrity Under Load — a worn or failed spring axle causes uneven load distribution, abnormal tire wear, and handling instability; replacing with a genuine OEM unit restores proper trailer dynamics.
- Genuine Multiquip OEM Part — sourced directly through Multiquip's authorized parts network, carrying part number EE46231 for accurate identification and warranty-compliant service.
The spring axle is the primary load-bearing and suspension component of the trailer, absorbing road shock through its leaf spring mounts while keeping the wheels properly aligned under the frame. On the TRLR45US1, the axle also provides the mounting interface for the electric brake assemblies, meaning its condition directly affects both ride quality and braking performance. When a spring axle bends, cracks, or loses its spring tension, the trailer can develop a dangerous lean, uneven tire contact, or compromised brake engagement — all of which make replacement a safety-critical repair.
