Multiquip 29463 Axle Assembly Spring Assembly 3500 Lbs with Electric Brakes

The Multiquip 29463 Axle Assembly Spring Assembly 3500 Lbs with Electric Brakes is a genuine OEM component designed for Multiquip trailer models including TRLR50WE, TRLR50XF, TRLR50XFE, TRLR25US, and the Trailers Single Axle series. As a factory-authorized OEM part, 29463 is built to meet the exact load rating, spring rate, and brake specifications of the original assembly. This complete unit integrates the axle, spring suspension, and electric brake system in a single replacement, ensuring all structural and braking components work together as engineered. Confirm your trailer model before ordering to ensure proper fitment.

Key Features

• Genuine OEM Brake and Load Certification — Rated to the factory 3500 lb. capacity with electric brakes that meet the original stopping-force specification — critical for safe trailer operation on public roads.
• Complete Integrated Assembly — Axle, leaf spring suspension, and electric brake hardware ship as a single unit, so every mating component is sized and matched from the start.
• Confirmed Fitment for Multiquip Trailer Models — Verified for TRLR50WE, TRLR50XF, TRLR50XFE, TRLR25US, and Trailers Single Axle — cross-reference your model before purchasing.
• Electric Brake Integration — The built-in electric brake assembly connects directly to the trailer's brake controller wiring harness, maintaining proper stopping authority at rated load.
• Suspension and Structural Integrity in One Kit — Replacing the full assembly restores correct spring deflection, axle alignment, and brake geometry simultaneously, preventing uneven tire wear and brake-side load imbalance.
• Safety-Critical Compliance — Brake performance, axle load rating, and spring specification on towed equipment are subject to DOT and site safety requirements — using the correct OEM-rated assembly keeps your trailer compliant.

The axle assembly carries the full static and dynamic load of the trailer and transfers it evenly to the road surface through the leaf spring suspension. The spring pack absorbs road shock and maintains consistent ride height under load, protecting both the trailer frame and its cargo. The integrated electric brakes receive a signal from the tow vehicle's brake controller and apply clamping force to slow the trailer independently — when this assembly is worn, cracked, or the brakes are out of adjustment, stopping distances increase and trailer sway risk rises significantly.
