    • Overview

    Add a Weight-Distributing and Sway Control System to provide a more level ride, greater steering and brake control. The STEADi-FLEX system combines a Weight-Distributing unit and a Sway Control into one easy to use system.

    Reese has improved another product. A complete redesign of the head makes this unit much easier for the end user to setup. It still has all of the great benefits of past Reese weight distribution products. Be sure to match your trailers Gross Trailer Weight and Tongue Weight with the proper size Weight Distribution unit.

    • Maximum Rated Load Capacity: 6,000 lbs. Gross Trailer Wt. / 400 to 600 lb Tongue Wt.
    • Includes Adjustable Hitch Shank
    • Tapered Spring Bars attach with a simple pin and clip
    • Integrated Friction Sway Control with Automotive Friction Material as used on Vehicle Brakes
    • Sway Control Provides Consistent Control in Various Weather Conditions
    • Reese STEADi-FLEX® Washer System Allows for Easy Head Adjustment and Does not Require Head Removal for Washer Adjustment
    • New Redesigned Hitch Head makes bar connections easier
    • Clamp on Brackets and Adjustable Pad Hangers Allow for Placement on Trailer Frames without Removing the Gas Bottles/Batteries
    • Life Handle Accessory Included to Reduce the Amount of Lifting Required by the Trailer Jack when Preloading the WD System
    • Limited Lifetime Warranty
    • Ball Sold Separately: #5851
