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.
