Description

The Equal-i-zer 90-01-0401 is a fully finished head box for a weight distribution hitch system. It is designed for a 4,000 lb towing capacity and does not include the shank, which must be purchased separately to match the vehicle's hitch receiver. It is a critical component of the Equal-i-zer 4-point sway control and weight distribution hitch, providing sway control and distributing weight evenly for a safer and more stable towing experience.
