Hitch Shank Specifications

On occasion, a specialty shank may be needed to correctly match your tow vehicle to your trailer. All Equal-i-zer® hitch shanks can be used in either the up (rise) or down (drop) position.

Shank model 90-02-4100 (90-02-4150 for 4K model) is included with your purchase of a complete Equal-i-zer® sway control hitch. Other specialty shanks may be combined with our No-Shank hitch models to create a package that works for your specific needs.
