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

Round bar weight distribution options: Camco's 800 lb Elite kit and CURT's 10,000 lb MV hitch, plus a CURT replacement head and two retainer sets.

By Bowen HigginsRV Editor at RV Gear Lab5 products comparedSpec-sheet researched

Round bar hitches slide the spring bars up into the head, usually cost less than trunnion designs and sit lower to the ground. This shortlist has two complete round bar hitches, an 800 lb Camco and a 10,000 lb CURT, and three parts: a replacement CURT head and two sets of retainers.

Ratings are quoted from each listing. Parts are labeled as parts, because they keep an existing hitch working but cannot level a trailer.

Before you buy

What Matters Before You Choose a Round Bar Weight Distribution Hitch

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

01
Round bar basics
Round spring bars slide up into the head, which usually keeps cost down and sits lower than trunnion bars. They need lubrication at the contact points. CURT 17052 has a grease zerk and says grease must be applied.
02
Rating match at round bar
Camco Elite Round Bar 800 is an 800 lb kit, while CURT 17052 is rated up to 10,000 lb. Match the loaded tongue weight and trailer weight. A far larger rating rides stiff.
03
Sway control at round bar
Camco Elite Round Bar 800 includes a sway control friction bar, and CURT 17052 includes none. Add-on friction bars are usually loosened for backing. Plan for that.
04
Parts fit
CURT 17075 Head fits certain CURT round bar hitches, and CURT 19302 Retainers fit 17050, 17051, 17052 and 17057. A wrong part will not fit. Match the part number.
05
Retainers matter
Retainers keep the spring bars locked onto the head while towing. A missing retainer can let a bar slip. Replace them promptly.
