Weight Distribution Hitch Calculator

Compare steer-axle weight before hitching, with the trailer hitched and WDH off, and with the WDH engaged.

What this tells you

The calculator estimates how much front-axle load was removed when the trailer was hitched and how much was restored when the weight-distribution system was engaged.
