Weight Distribution Hitches
Fastway e2 Hitch: An Honest Assessment
The hitch that made integrated sway control normal at the entry end of the market. Its strengths and its limits are both in the same design decision.

How we assessed these: Assessed from the manufacturer's own published model tables, ratings and mechanism description, and from the setup requirements the design implies. This site has not towed this hitch, runs no instrumented tests, and publishes no sway or load-transfer measurements of its own.
Short answer
Buy the Fastway e2 if you want weight distribution and sway control in one unit at the entry end of the market, and you tow mostly on pavement. Its friction is permanently engaged, so there is no bar to unhook before backing up and nothing to forget in the rain. Skip it if you tow on gravel or dirt, where grit on the friction faces is exactly what the design does not want.
The e2 is most people's first weight distribution hitch, and that shapes how it gets discussed. A lot of the criticism aimed at it is really criticism of a first-time setup - bars at the wrong angle, brackets at the wrong height, a tongue that was never weighed. Separating those from the design's genuine limits is what this page is for, because the limits are real and they are specific.
What problem it solves
Two at once. It redistributes tongue load, prying the hitch head and the trailer A-frame apart through tensioned spring bars so that weight which would otherwise sit entirely behind the tow vehicle's rear axle is pushed forward onto the front axle and back onto the trailer's own axles. That is what stops the nose-up, tail-down stance and restores steering feel and headlight aim.
And it resists yaw. Rather than bolting a friction bar diagonally alongside the hitch, the e2 generates sway resistance through steel-on-steel friction where the spring bars meet rigid brackets on the trailer frame. The manufacturer's own framing is the useful one: because the brackets are rigid and the friction comes from the bars working against them, there is nothing to connect, nothing to disconnect, and no stated restriction on backing, turning or wet weather.
The published numbers
Fastway publishes the e2 in two bar styles with nine ratings between them, and in every case the maximum tongue weight is exactly ten percent of the maximum trailer weight. That matters when you shop, because it means the model number is chosen by your measured tongue weight, not by your trailer's sticker.
| Bar style | Max trailer weight | Max tongue weight |
|---|---|---|
| Trunnion | 4,500 lb | 450 lb |
| Trunnion | 6,000 lb | 600 lb |
| Trunnion | 8,000 lb | 800 lb |
| Trunnion | 10,000 lb | 1,000 lb |
| Trunnion | 12,000 lb | 1,200 lb |
| Round bar | 6,000 lb | 600 lb |
| Round bar | 8,000 lb | 800 lb |
| Round bar | 10,000 lb | 1,000 lb |
Read off the manufacturer's own published model tables. A 2-5/16 in ball comes pre-installed on the 6,000 lb and heavier models; the 4,500 lb trunnion is supplied without one, so budget for a ball if that is the model you need.
Two practical consequences fall out of that table. First, the trunnion range starts lower and goes higher, so if your tongue weight is near either end, trunnion is the only style that covers you. Second, nothing here reaches the capacities a large fifth-wheel-adjacent travel trailer needs - the e2 tops out at 12,000 lb gross trailer weight, and beyond that you are shopping in a different class of hitch.
Round bar or trunnion: the one specification people get wrong
This is not a quality tier. Round bars hang below the hitch head and give a lower-profile head assembly; trunnion bars insert horizontally into the head and sit higher, which buys ground clearance under the bars. The decision is made by your trailer's A-frame height and how much clearance you need at the bottom of a steep driveway or a launch ramp.
- Pick trunnion if the bars would otherwise sit low enough to catch on driveway aprons, ramps or rough ground - and if you need the 4,500 lb or 12,000 lb rating, since only trunnion is published at those ends.
- Pick round bar if clearance is not a problem and you prefer the lower head, which some owners find easier to work around when coupling.
- Either way, buy to your measured tongue weight, not the trailer's gross rating. A trailer rated 8,000 lb loaded to 5,000 lb with 550 lb on the tongue wants the 6,000 lb model, not the 8,000 lb one - oversized bars transfer harshly and ride badly.
- Check A-frame length before ordering. Weight distribution brackets need a straight run of A-frame to clamp to, and propane tanks, battery boxes and front storage boxes all compete for that space.
What it does not solve
It does not create capacity. If your tongue weight exceeds what the vehicle's payload allows, a weight distribution hitch spreads that load across three axles but does not reduce it by a single pound - the placard limit is still the placard limit. It also will not rescue a badly loaded trailer: too little tongue weight is the dominant cause of sway, and no amount of friction at the brackets compensates for cargo stacked behind the axle.
And it is not a fifth-wheel-class solution. If you are consistently at the top of its published range, the honest recommendation is to step up rather than run a hitch at its limit. Whether you need weight distribution at all is the question to settle first, and how much tongue weight is too much covers the limit that usually binds before the hitch does.
Installation and setup realities
Setup is the part that decides whether owners like this hitch. It is not difficult, but it is fussy, and it is measurement work rather than wrench work.
What a first setup actually involves
Measure the vehicle unhitched
Record the height of a fixed point over each wheel arch, front and rear, with the vehicle loaded as it will travel but with no trailer attached. These are your reference numbers.
Set the ball height and head angle
The head tilts, and that tilt sets how much the bars preload. Start from the manual's recommended washer stack or tilt angle for your bar rating rather than guessing.
Couple and raise
Hitch the loaded trailer, then raise the whole front of the rig on the tongue jack before fitting the bars. The jack does the lifting; you should never be fighting the bars.
Fit the bars and set bracket height
Position the brackets so the bars sit at the angle the manual calls for, then tension them. Bracket height is the main adjustment you will revisit.
Lower and re-measure
Drop the rig onto its suspension and re-measure both arches. You are aiming to restore most of the front-arch drop the trailer caused while keeping the trailer level - adjust bracket height or head tilt and repeat until both are true.
Write the final setting down
Bracket hole, washer count, bar angle. Put it on a label near the jack so you never have to re-derive it in a dark campground.
The full sequence, including how much front-axle restoration to aim for, is in the weight distribution setup guide. Budget an hour the first time and ten minutes every time after.
The maintenance trap
Here is the single most important thing to know about this hitch, and it is counter-intuitive enough that people get it wrong with the best of intentions: the friction surfaces must stay clean and dry. Sway resistance comes from steel rubbing on steel, so greasing the bars where they meet the brackets destroys exactly the effect you bought the hitch for.
The same logic explains the e2's real environmental limit. Dust and grit on the friction faces act like a dry lubricant and change how the hitch behaves, so owners who tow long distances on gravel, forest roads or dirt get less consistent sway resistance than the design intends. That is not a defect; it is the trade-off of generating friction out in the open rather than inside a sealed mechanism. If most of your towing is unpaved, a cam-based system is the better architecture.
The noise
It creaks and clunks in slow tight turns - pulling into a fuel station, maneuvering on a campsite, swinging through a sharp junction. This is normal for every friction-based weight distribution hitch, the e2 included, and it is the single most common surprise for a first-time owner. The sound is the bars working against the brackets, which is the hitch doing its job audibly.
Worth knowing, though: noise that appears suddenly, or that happens in a straight line rather than in turns, is not this. That is usually a loose ball, a worn shank in the receiver, or the mount rattling in the tube - a different problem with a cheap fix.
Who should buy something else
- You tow mainly on dirt or gravel. Grit on the friction faces is the e2's weak point. A dual-cam system keeps its sway mechanism better protected.
- Your trailer already sways badly. The e2 resists yaw well for its class, but a four-point design generates friction at more places and is the stronger answer to an existing problem.
- You hitch and unhitch constantly. Snap-up brackets are fine but repetitive; a clamp-on latch design is quicker trip after trip.
- You are above 12,000 lb gross trailer weight. Outside the published range entirely.
- Your truck sits level and the trailer tracks straight. Then you may need nothing at all, and that is a legitimate answer.

Fastway e2 Weight Distribution Hitch with Built-in Sway Control
Fastway · Best for a first weight distribution hitch
Sway control by steel-on-steel friction between the bars and their brackets, with no separate friction bar and nothing to remove before backing up. Available in round and trunnion bar versions, which is the detail to get right: trunnion for ground clearance, round for a lower-profile head.
Published specifications
- Trunnion bar models
- 4,500 / 6,000 / 8,000 / 10,000 / 12,000 lb gross trailer weight source
- Round bar models
- 6,000 / 8,000 / 10,000 lb gross trailer weight source
- Maximum tongue weight
- 450 / 600 / 800 / 1,000 / 1,200 lb, matched to the model's trailer rating source

2. The step up
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.
Published specifications
- Models offered (gross trailer weight)
- 4,000, 6,000, 10,000, 12,000, 14,000 and 16,000 lb source
- Tongue weight rating
- Matched to each model: 400, 600, 1,000, 1,200, 1,400 and 1,600 lb source
- Sway control points
- Four - two in the hitch head sockets, two at the rigid trailer brackets source
- Warranty
- Limited lifetime warranty source
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.

3. The easier-hitching alternative
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
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.

4. The cheaper alternative
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
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.

The verdict
The e2 earns its reputation as the sensible first weight distribution hitch. It does both jobs in one unit, its sway control cannot be left disconnected by accident, and its published model table is wide enough that most half-ton travel trailer owners will find their tongue weight in it. The price of that simplicity is a mechanism exposed to the weather and the road, which means it rewards pavement towing and punishes gravel, and a maintenance rule that runs opposite to every other hitch habit.
Buy it for a first travel trailer behind a half-ton or an SUV, set it up properly once, keep the friction faces clean, and expect it to creak in car parks. If any of those conditions does not describe you, one of the three alternatives above probably fits better - and the roundup of hitches with integrated sway control lays the class out side by side.
Key takeaways
- Sway control is built in and always engaged - nothing to unhook before reversing.
- Nine published models; maximum tongue weight is ten percent of trailer weight in every one.
- Trunnion covers the 4,500 lb and 12,000 lb ends; round bar does not.
- Buy to measured tongue weight, never the trailer's gross sticker.
- Keep the friction faces clean and dry - greasing them defeats the hitch.
- Creaking in tight slow turns is normal; sudden straight-line noise is not.
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.
- Fastway e2 hitch - published model tables for both bar styles (trunnion 4,500 to 12,000 lb, round bar 6,000 to 10,000 lb, each with its matching maximum tongue weight) and the built-in sway control description
- Equal-i-zer 4-point sway control hitch - published model table (4K through 16K gross trailer weight with matching tongue weight ratings) and four-point friction description
- Blue Ox SwayPro weight distribution hitch - published tongue weight bands and towing capacity
- 49 CFR 567.4 - certification label content, including Gross Vehicle Weight Rating and Gross Axle Weight Rating
Common questions
- Does the Fastway e2 have sway control built in?
- Yes. Sway resistance is generated by the spring bars working against rigid brackets on the trailer frame, so there is no separate friction bar, nothing to connect and nothing to remove before backing up or in wet weather.
- Should I get the round bar or the trunnion e2?
- Trunnion if you want more clearance under the bars, or if you need the 4,500 lb or 12,000 lb rating, which only trunnion is published at. Round bar if clearance is not a concern and you prefer the lower head. Neither is stronger than the other at the same rating.
- Can you back up with a Fastway e2?
- Yes. The manufacturer states there is nothing to remove for backing, turning or inclement weather, because the sway control is integral rather than an add-on bar. Keep reversing angles moderate as you would with any weight distribution hitch.
- Should I grease a Fastway e2 hitch?
- Grease the hitch ball and coupler, never the spring bar ends or the bracket faces they bear on. Those surfaces generate the sway control by friction, and lubricating them removes it.
- Which e2 model do I need?
- The one whose maximum tongue weight is just above your measured loaded tongue weight - not the one matching your trailer's gross rating. Oversized bars ride harshly and transfer load more aggressively than the setup needs.
