Weight Distribution Hitches

The Best Weight Distribution Hitches with Sway Control

One assembly doing two jobs. Which one is right comes down to your measured tongue weight and how your trailer's A-frame is laid out.

How we assessed these: Selected from manufacturers' published specifications and the mechanism each design uses. We have not towed these back to back and we publish no measured test data; where a maker does not publish a figure we leave it out rather than estimate it.

Short answer

For most travel trailers, a hitch with four-point friction or cam-based sway control built into the head is the right buy: it levels the tow vehicle and resists yaw with one assembly and nothing to disconnect before reversing.

Your measured, loaded tongue weight decides which one. Not your trailer's brochure weight, not its length, and not what the dealer put on the invoice. If you have not measured it, start at how to measure tongue weight - it takes a trip to a public scale and nothing else.

How we chose

  1. Sizing granularity. A hitch sold in narrow tongue weight bands makes the correct choice obvious. One sold as a single wide-range model does not.
  2. Ground clearance. Round bars hang lower than trunnion bars. On a steep driveway or a ferry ramp that is the difference between a scrape and a non-event.
  3. Setup alone. Snap-up brackets under tension are the step people get wrong when there is nobody to help.
  4. Whether sway control can be left off. Integral friction and cams cannot. A bolt-on bar can, and eventually will be.

The picks in detail

1. Best overall

Equal-i-zer 4-point Sway Control Hitch

Equal-i-zer · Best for travel trailers that already sway

The reference point for integrated sway control. Friction happens at four places at once - both L-brackets and both sockets - so resistance is always on rather than something you remember to engage. Setup is bracket-height and bar-angle work, and it rattles; both are the price of a system with no separate parts to forget.

We have not sourced a full specification table for this model from the manufacturer’s own site at a stable address. Rather than repeat figures we cannot cite, the assessment above is limited to what the design and the maker’s published description genuinely establish.

What works

  • Sway resistance is built into the geometry, so there is nothing to connect or disconnect at the ramp
  • Works in reverse and in the wet, unlike a friction bar you have to release
  • One assembly rather than a hitch plus a bolt-on sway bar

What does not

  • Audible rattle and creak at low speed is normal and surprises first-time owners
  • Bracket height and bar angle have to be set properly or the sway control does little

Skip it if

Skip it if your loaded tongue weight sits well inside your receiver's weight-carrying rating and the truck stays level - you would be buying hardware to solve a problem you do not have.

2. Best for sizing precisely

Blue Ox SwayPro Weight Distribution Hitch

Blue Ox · Best for owners who hitch and unhitch often

Underslung spring bars on clamp-on latches, which makes hitching faster than chain-and-snap-up systems and keeps the bars out of the way of a low A-frame. Blue Ox publishes the range in tongue-weight bands rather than one do-everything model, so the sizing decision is made before you buy.

Published specifications

Tongue weight bands offered
350, 550, 750, 1000, 1500 and 2000 lb source
Maximum gross towing weight
20,000 lb source
Shank sizes
2 in receiver, or 2-1/2 in on the BXW2000 source

What works

  • Latches clamp on rather than needing chains snapped up under tension
  • Sold in defined tongue-weight bands, which makes correct sizing the default
  • Underslung bars clear low A-frames and front storage boxes

What does not

  • Bar bands are narrow, so a big change in how you load the trailer can put you in the wrong band
  • Clamp-on brackets are another part to keep clean and lubricated

Skip it if

Not the one if your loaded tongue weight sits near the top of a band - buy up a band, because a bar run at its limit transfers less than a bar running in the middle of its range.

3. Best for heavy trailers

CURT TruTrack 4P Weight Distribution Hitch (10-15K)

CURT · Best for heavy travel trailers near 15,000 lb

Four-point sway control with adjustable friction, rated to a 15,000 lb trailer and 1,500 lb tongue. The adjustability is the point: you can dial resistance up for a long, tall trailer and back it off for a short one, instead of living with whatever the geometry gives you.

Published specifications

Gross trailer weight
10,000-15,000 lb source
Tongue weight
1,000-1,500 lb source
Rise
5.75 in source
Product weight
123.6 lb source

What works

  • Friction is adjustable rather than fixed by the geometry
  • Rated range covers the tongue weights that half-ton trucks genuinely struggle with
  • Limited lifetime warranty on the structure

What does not

  • At 123.6 lb assembled it is a heavy thing to lift on and off a shank
  • The 10,000 lb floor means it is over-specified for a small trailer

Skip it if

Wrong tool below about 10,000 lb gross trailer weight - under the rated floor the bars barely flex, so you get the weight penalty without the load transfer.

4. Best for solo setup

Husky Towing Centerline TS Weight Distribution Hitch

Husky Towing · Best for setting up single-handed

Trunnion bars with sway control built into the head rather than bolted alongside it, and no chains to snap up - the bars seat and lock. For owners who found a chain-type hitch awkward to set up alone, the hook-up sequence is the whole argument.

We have not sourced a full specification table for this model from the manufacturer’s own site at a stable address. Rather than repeat figures we cannot cite, the assessment above is limited to what the design and the maker’s published description genuinely establish.

What works

  • No chains to tension, which is the hardest part of a conventional hitch to do alone
  • Trunnion bars sit higher than round bars and clear steep driveways better
  • Sway control integrated rather than a separate bolt-on bar

What does not

  • Head height and washer stack still have to be set correctly, which is the fiddly part
  • Fewer bar ratings offered than the biggest brands, so sizing options are coarser

Skip it if

Not the choice if your tongue weight falls between its bar ratings - a mismatched bar is worse than a simpler hitch sized correctly.

5. Lightest to handle

Andersen No-Sway Weight Distribution Hitch

Andersen Hitches · Best for anyone who struggles with bar weight

A chain-and-bracket system instead of spring bars, which cuts the assembled weight dramatically and takes the greasy steel bars out of the equation. Sway resistance comes from a friction cone at the ball rather than from bar friction, so it keeps working in reverse.

We have not sourced a full specification table for this model from the manufacturer’s own site at a stable address. Rather than repeat figures we cannot cite, the assessment above is limited to what the design and the maker’s published description genuinely establish.

What works

  • Far lighter to lift and store than a conventional spring-bar system
  • No greased bars to handle, and no bars to drag on a steep transition
  • Tension is set with a wrench rather than a snap-up bracket

What does not

  • Chains and the friction cone need periodic re-tensioning and inspection
  • Behaves differently from a spring-bar hitch, so advice written for those does not transfer cleanly

Skip it if

Not for you if you want a system a trailer shop down the road will recognize instantly - most of the setup advice you will find assumes spring bars.

6. Best value

CURT Round Bar Weight Distribution Hitch with Sway Control (14K)

CURT · Best for mid-size travel trailers

A conventional round-bar system with integrated lubrication and sway control, rated to 14,000 lb gross and 1,400 lb tongue. The built-in lubrication matters more than it sounds: a dry weight distribution head is the usual source of the groaning people mistake for a failing hitch.

Published specifications

Gross trailer weight
14,000 lb source
Tongue weight
1,400 lb source
Shipping weight
102 lb source

What works

  • Integrated lubrication at the head, which is where the noise usually comes from
  • Round bars sit lower and clear more trailer tongues than trunnion bars
  • Limited lifetime warranty

What does not

  • Round bars hang lower than trunnion bars and are the first thing to catch on a steep driveway
  • Sway control here is a function of the head, not an adjustable four-point system

Skip it if

Skip it if you regularly cross steep transitions - a round bar is the lowest part of the whole rig and will find the pavement before anything else does.

Sizing the bars before you choose a brand

Spring bars carry a tongue weight rating, and you want your actual loaded figure near the middle of it. Blue Ox publishes SwayPro in 350, 550, 750, 1,000, 1,500 and 2,000 lb bands with a 20,000 lb maximum gross towing weight; CURT publishes the TruTrack 4P at 10,000-15,000 lb gross with a 1,000-1,500 lb tongue range. Those published ranges are the specification to shop on.

Key takeaways

  • Measure loaded tongue weight first - it decides the bar rating, which decides everything else.
  • Bars transfer best in the middle of their range, so size up at a band boundary rather than down.
  • Trunnion bars clear steep transitions; round bars sit lower and are cheaper.
  • Integrated sway control is the feature worth paying for if sway is your complaint.

How we sourced this

Every figure on this page came from one of the following, each fetched while the page was written. Where a manufacturer or regulator does not publish a number, we say so rather than estimate it.

Common questions

Can I fit a weight distribution hitch to any receiver?
Check the receiver's weight-distributing rating, which is a separate and higher figure than its weight-carrying rating. Both are on the receiver's label. Some lighter receivers carry no weight-distributing rating at all.
Do I need the exact bar rating or is close enough fine?
Close matters. A bar far above your tongue weight barely flexes and transfers little; a bar at its ceiling flexes less than designed. Aim for the middle of the range.
Will this fix a truck that is over its payload?
No. Weight distribution moves load between axles; it does not reduce the total weight the vehicle is carrying. Payload is a separate limit and a weight distribution hitch does not raise it.
How long does setup take the first time?
Budget an afternoon for the first setup including measuring, adjusting head angle, and a test drive followed by fine adjustment. Subsequent hitch-ups take minutes.
