Lippert Trailer Axle Beam - 4 in Drop (Beam Only) - Part #V000378958

Product Overview

The Lippert V000378958 is a heavy-duty drop axle beam designed for trailer applications requiring lower ride height and improved stability. This axle features a 4-inch drop design, allowing the trailer deck to sit lower to the ground, making loading and towing safer and more efficient.

This configuration is supplied as a beam-only assembly with welded brake backing plates, making it ideal for custom trailer builds, axle replacements, or upgrades where existing hubs, drums, or brake components will be reused or selected separately.
