Weight Distribution Hitches
Equal-i-zer 4-point vs Husky Centerline TS
Two integrated sway control systems that hitch up very differently. If you often set up alone, that difference decides it.

Short answer
Equal-i-zer uses four friction points and snap-up style setup; Husky's Centerline TS uses trunnion bars that seat and lock without chains. If you hitch up alone and dislike tensioning chains under load, the Husky is the easier system to live with.
Setup is the real difference
Tensioning a chain under load with a lever bar is the step people find awkward, and it is the step most likely to be done badly when there is nobody to help. Centerline TS removes it: the bars seat into the head and lock. Equal-i-zer's setup is well documented and widely understood, but it is the more physical of the two.
Against that, Equal-i-zer has an install base large enough that almost any question you have has been answered somewhere, and almost any RV shop has seen one. That is worth something real when you are 300 miles from home and something needs adjusting.
Bar style and clearance
Centerline TS runs trunnion bars, which sit higher than round bars and clear steep driveway transitions better. Equal-i-zer's arrangement is more conventional. If your driveway has a sharp lip at the street, that is a point in Husky's favor; if your A-frame is crowded, measure both before deciding.

1. Most proven
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. Easiest hitch-up
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.

| Equal-i-zer 4-point | Husky Centerline TS | |
|---|---|---|
| Sway control | Four friction points | Integrated in the head |

| Support and documentation | Very broad | Narrower |
| Noise | Creak and rattle in slow turns | Generally quieter |
Key takeaways
- The deciding factor is usually setup effort, not performance.
- Centerline TS removes the chain-tensioning step; Equal-i-zer does not.
- Trunnion bars on the Husky give more ground clearance.
- Equal-i-zer's ubiquity is a genuine advantage when you need help away from home.
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
- Is the Husky as good at controlling sway?
- Both integrate sway resistance into the head rather than relying on a separate bar. Neither publishes comparative test data, and nor do we - the mechanisms differ but both are always-engaged designs.
- Which is quieter?
- Owners generally report the Husky as quieter, because Equal-i-zer's friction faces creak in slow turns by design. Noise is not a performance indicator either way.
- Can I use either with a surge-brake boat trailer?
- Check the trailer manufacturer's guidance. Some surge couplers and A-frames are not compatible with spring bar brackets, and the trailer maker's restriction wins.
