Seen in images is the Equal-i-zer Model #90-00-1000 four point trailer weight distribution and sway control system.
This model is rated for maximum 1,000 pounds trailer Tongue Weight and maximum 10,000 pounds trailer Gross Towing Weight.
This model will accommodate 3", 4", 5" and 6" trailer frames.
This model is for 2" receivers but can work with 2 - 1/2" receivers with an adaptor.
This model features a 12" shank with up to 7" rise and/or 3" drop.
This unit includes a 2 - 5/16" ball.
All OEM parts are present and in very good working condition.
The system seen was used on a 2018 Forest River Salem Cruise Lite 180RT and is being sold because that trailer was traded in for another much heavier trailer which makes this Equal-i-zer Model #90-00-1000 under rated for the new trailer.
