Didn't know why I was having "sway" issues when towing with my new Tremor. This locked down 90% of it on the medium setting. May still tweek it with the stiffest setting. Easy install, took about an hour with two sets of hands.

Hardest parts were getting two bolts into the rusted holes on my 2018 Ford truck. Everything else was straight forward. A thread chaser would help.

Having used the other brand primarily in past and dealing with the all to familiar now issue of parts that don't fit the 2023 Super Duty trucks I was left wondering how well this part from Hellwig would work. Thankfully, it worked great. Installing all the mounting hardware was a breeze, especially the drops for the links. The bar is beefy enough, although not quite as beefy as the competition. Fortunately it has some adjustability, I have only used the middle setting and it seems to be doing a great job. Immediately I noticed improved steering response and flatter cornering. It also smoothed out towing my 5th wheel and removed all the side to side "wallowing" feeling you can get in wind or winding roads. Highly recommended now that I have them installed.

Very stout and does what sway bars are meant to do. Install directions are pretty vague. Driver-side link arm is very difficult to bolt onto frame because of another under-carriage component in the way of getting to nut (on a Ford F250) . I figured it out , but guidance from Hellwig could have saved me hours of time.

Came missing a bolt. Otherwise was simple to install and works great.

Installed in a bit over an hour. The instructions are a little confusing. Grease the bushings before assembly, this greasing instruction come after the assembly instructions, requiring disassembly to grease. On the F250 the driver's side is hard to assemble near the frame due to stuff being in the way. The instruction order can be modified to assemble the upper link through the plate before putting through the square frame hole. If you do it after, you can't fit your fingers or a wrench in the small gap.Overall, I had an immediate noticeable difference in the sway. Have not tried pulling the 5th wheel yet, but I am certain it will have helped or fixed my issue. I recommend this product.Tools needed or handy: Socket set, 3 different sizes of open-ended wrenches, crescent wrench, hammer or rubber mallet (grease/lubricant is included), and extra set of hands was helpful (my 15 year old was great help)

This went on fairly simple, I'm 66 and other than blocking it up while installing because of the weight there was only one issue with the installation - not a product issue.If you're ordering this, purchase a 10-1.5 tap (10mm with 1.5 pitch thread). Use it carefully to clean out the threads on shock mounts on the axle. Probably 1/4 of the installation time was spent doing this.As for the product, the test drive went well and I can already feel the difference, I expect a better handling vehicle (F250 SD) with a load on.

Install is straight forward good directions, takes maybe a half hour to install once you have the tools ready to go. Once installed very noticeable difference, really stiffened up the rear suspension flex, put 1700 miles on the truck hauling a 14000lb box trailet

Hands down the best modification I have ever done on one of my vehicles. I have an 11,000 lb. 5th wheel that I towed behind my 2016 F250. It pulled like a dream. I upgraded trucks and went with a 2021 F250 Tremor. I anticipated that it wouldn't tow as nice as the 2016 due to the Tremor being designed for off-roading, but I didn't expect it to be as bad as it was.My first trip pulling my RV in the the Tremor was 800 miles one-way, and I was white knuckling it most of the way. The Tremor does not handle well at all pulling that much weight. Plenty of power, but horrible sway. In fact, with no weight at all behind it, I was disappointed in how it cornered. Very soft with LOTS of roll. I'm not mad at Ford for this. It's designed that way for a purpose, but I bought the Tremor for the appearance alone with no intention to off road it.I did some research and read on the forums where the Tremors don't come with a rear sway bar and guys were putting aftermarket sway bars in their Tremors with good luck. I've done a lot of upgrades over the years and have spent good money on components that I didn't think made much of a difference, so I was hesitant to buy this sway bar due to how much it is. I sucked it up and opened up the wallet. Man am I glad I did. Hands down the best mod I've ever done. I noticed improvement immediately. I mean, like pulling out of my garage and onto the street immediately. You couldn't wipe the grin off my face on my test drive.Installation was SUPER easy. Some other reviews talked about having to remove fuel tanks or loosen brackets. I didn't have to do any of that. I had easy access to everything. On the drivers side, there is a bracket you mount to a hole in the frame rail and it was not possible to get my fingers up there to install the washer and nut. My solution was to insert the nut into the box end of my wrench, then tape it and the washer to the wrench with some masking tape, being careful to make sure the holes were aligned. This allowed me to use the wrench to get into the tight area and start the bolt by finger. I got it on the first try and took all of 2 minutes. Slow and steady. Hopefully this isn't the reason for people taking off tanks and brackets. Maybe the new models have some design changes? The manual says to mount to the softest hole of the sway bar first, but I mounted to the middle hole. I wanted significant improvement out of the gate and that's what I got.I've not pulled my camper again since installing the Hellwig, but I now have complete control of the truck where before it was controlling me in the turns, so I expect the ride will be significantly improved.If your experience is similar to mine and you are on the fence, stop thinking about it and get this sway bar.

I'll start with install, pretty straight forward but instructions were definitely missing some detail and were vague. Bar itself is extremely heavy duty, coming from no factory sway bar to this I noticed a huge difference in stability towing so it does do exactly what it's supposed to. I am disappointed that after being on the truck just a couple weeks components and hardware already have surface rust, for the price I expected better.

I added this on my 2017 F350. I have the towing package but for some reason didn’t come with a sway bar. I tow a 38’ camper and in the wind it pushes me around quit a bit. I added this and I’m totally blown away by the difference it makes when towing! Plus the weight up top with my rzr it helps with the sway I get cornering at low speeds. I absolutely love what this sway bar has done.
