Reese does not sell or make the Equal-i-zer WDH. that is a brand name of a WDH with integrated sway control, made by Progress Mfg. Inc. in Utah.
too many use the term "equalizer" to describe other WDH systems, when the name "Equal-i-zer" is a registered trademark name for Progress Mfg. Inc's hitches, which are very different from Reese hitches.
