5 Best Adjustable Weight Distribution Hitch in 2026: A Practical RV Guide

Adjustable weight distribution options: Camco's clamp-adjusted TR3, CURT's flip-shank deep drop and greased round bar, plus a flip shank and a spare bar.

By Hardcastle's RV Editors

10 min read5 products evaluated

Adjustability in a weight distribution hitch shows up in three places: the shank (drop or rise), the head height and the sway control. This shortlist covers a clamp-adjusted Camco kit, a CURT hitch with a flip-over deep drop shank, a CURT round bar, and two parts (a flip shank and a replacement trunnion bar).

Ratings are quoted from each listing, and two entries are parts rather than hitches. Adjustment helps match ride height, but it does not change a hitch's rating.

What Matters Before You Choose an Adjustable Weight Distribution Hitch

Key buying criteria so you get the right fit the first time.

  1. Shank drop and rise

    CURT 17123 and CURT Deep Drop 8K-10K flip to give up to 7 inches of drop or 10-1/2 inches of rise. That range matches most trucks and trailers. Measure ball height with the trailer level.

  2. Head height holes

  4. Adjustment is not capacity

    Adjustability sets ride height and sway but does not raise a rating. Match tongue weight and gross trailer weight to the loaded trailer. CURT Deep Drop 8K-10K is sold for 8,000 to 10,000 lb.

  5. Parts versus hitches

    CURT 17123 Shank and CURT 17337 Bar are parts. They help only with a compatible hitch. Check the model.
