6 Best Weight Distribution Hitch With Sway Control in 2026: A Practical RV Guide
Six weight distribution hitches that include sway control, from a 600 lb Equal-i-zer to 15,000 lb CURT trunnion kits, with notes on friction bars and shanks.
By Hardcastle's RV Editors
10 min read6 products evaluated
Weight distribution levels the load, while sway control resists the side-to-side motion a trailer can develop; many kits now bundle both. This shortlist focuses on the weight distribution side of six kits that include some form of sway control, from integrated four-point friction to a bolt-on friction bar and a clamp-adjusted system.
Sizing starts with loaded tongue weight, usually 10 to 15 percent of the loaded trailer weight, then the stated gross trailer weight. Hardware cannot fix a tongue weight that is too low, so the load must be right before any sway system helps.

How We Built This Shortlist
Each pick was assessed across 5 criteria weighted for real-world use.
- Weight distribution first
- Ratings and bar type were compared before sway features, since leveling is the primary job.
- Sway control type
- Integrated, switchable and bolt-on friction systems were separated.
- Stated ratings
- Gross trailer weight and tongue weight figures were compared where given.
- Included parts
- Shanks and balls were checked, since missing pieces add cost.
- Title versus text
- Listings with conflicting ratings were flagged.
What Matters Before You Choose a Weight Distribution Hitch With Sway Control
Key buying criteria so you get the right fit the first time.
Sway control type at with sway control
Integrated four-point systems such as Equal-i-zer 90-00-0601 apply friction at fixed brackets, while CURT 17422 and 17322 add a separate friction bar kit. Camco TR3 uses clamp-adjusted friction that can be turned off. Each needs different handling when backing or on slick roads.
Tongue weight before hardware
Sway is often caused by tongue weight below about 10 percent of the loaded trailer weight, so hardware cannot replace correct loading. Weigh the loaded tongue and shift cargo forward if needed. Then choose a kit whose tongue weight rating sits at or somewhat above that figure.
Rating match at with sway control
Equal-i-zer 90-00-0601 is rated 6,000 lb and 600 lb tongue weight, while CURT 17422 is rated up to 15,000 lb without a stated tongue weight. A kit far above your load can feel stiff, while one below it can bottom out. Compare stated numbers to your loaded trailer.
Shank and ball
A kit that omits the shank needs one bought separately with the right drop and rise. Equal-i-zer 90-00-0601 says it does not include a shank, while CURT 17422 includes a ball. Check the listing's included parts.
Backing and release
Bolt-on friction bars and clamp-adjusted systems often need to be loosened or turned off for sharp turns or ice. Integrated designs stay engaged. Read the manual for the release procedure.

Integrated vs Add-On Sway Control
- Integrated
- Integrated sway control is built into the hitch and stays engaged. Equal-i-zer 90-00-0601 is the integrated pick.
- Add-on
- Add-on sway control is a separate friction bar that may be loosened for backing. CURT 17422, CURT 17322 and Camco TR3 use this approach.
Choose Equal-i-zer 90-00-0601 for always-on sway control, and a CURT or Camco kit when you want to turn it off.
By Backing Habits
| Habit | Recommended pick |
|---|---|
| Backs up often, wants a switch | Camco TR3 1,200 |
| Backs up often, lighter trailer | Camco TR3 800 |
| Rarely backs up, wants always-on | Equal-i-zer 90-00-0601 |
| Does not mind loosening a bar | CURT 17322 |

Before You Bring One Home
Does sway control replace weight distribution?
No. Weight distribution restores front axle load and levels the rig, while sway control resists side-to-side motion. Many kits include both, but friction bars alone do not distribute weight.
What causes trailer sway even with a good hitch?
Common causes are tongue weight below 10 percent, speed, crosswinds and low tire pressure. Hardware reduces sway but cannot fix a poor load. Correct the load first.
Is integrated sway control worth more than a bolt-on bar?
It stays engaged and needs no removal, which many owners like. A bolt-on bar is cheaper and can be turned off. Equal-i-zer 90-00-0601 is the integrated choice here.
How do I set up sway control?
Level the trailer, tension the spring bars, then tighten the sway control per the manual. Re-check after the first trip.
Do I need to remove sway control for backing?
Bolt-on friction bars and clamp-adjusted systems often need releasing for tight turns. Integrated systems like Equal-i-zer 90-00-0601 stay on. Follow the manufacturer's instructions.
