Dexter Removable Torsion Trailing Arm and Hardware Kit K71-069-00, 5.2K thru 7K, for Idler or Disc Brake Axles

The Dexter K71-069-00 Removable Torsion Trailing Arm and Hardware Kit is a replacement torsion arm assembly built for trailer axles rated 5.2K thru 7K, suited to axles equipped with either idler hubs or disc brakes. Torsion trailing arms are the suspension component that connects the axle beam to the hub end, allowing the axle to flex independently at each wheel for a smoother ride than a straight-beam setup. This kit is designed as a removable arm, meaning the trailing arm can be unbolted and replaced without disturbing the torsion axle's rubber cord suspension inside the axle tube, simplifying service when an arm is bent, cracked, or worn. The kit includes the trailing arm along with the hardware needed to mount it, so buyers do not need to source bolts or fasteners separately. It is intended for trailer owners, fabricators, and repair shops replacing a damaged or worn torsion arm on a boat trailer axle within the 5.2K to 7K capacity range. Because it fits axles set up for either idler or disc brake hub configurations, it covers both non-braked and disc-braked trailer axle applications built to this arm specification.
