Medium, Heavy and Super Heavy Duty Weight Distribution Systems

The Medium (600lb), Heavy (800lb) and Super Heavy Duty (1200lb) WDS kits have been designed to be used with a Hayman Reese Class 4 Heavy Duty Towbar to safely tow trailers.

The height of the towball can be raised and lowered to address the trailer’s coupling at the correct level by using the adjustable shanks. The heavy duty cam washers and bolts (fine tooth adjustment washers for Super Heavy Duty) also allow the adjustment of the towball position. This is used to set the head angle, which in turn sets the angle of the spring bars.

These units can be adjusted to suit passenger and light commercial vehicles, and can be easily setup on your new vehicle and trailer as you change them. Shown below are some typical setups.

A range of Drop Shanks is available to setup 4WDs and applications where the lowest/highest setting is not low/high enough. Always seek advice from your nearest Hayman Reese Distributor before fitting different sized Drop Shanks to check compatibility to your vehicle.
