Description

This Fifth Wheel Pin Box acts as a buffer, arresting the transfer of road impact between the tow vehicle and the coach. It produces smooth, stabilized towing performance, transferring shock to an airbag via a scissors action. This improves the overall ride while protecting the 5th wheel trailer, improving handling and enhancing towing performance. It is designed for universal fitment on fifth-wheel trailers that accept a king pin coupler.
