Best Upgrade I've Done for my F150
If you are towing anything heavy whats so ever, this is the best upgrade you can do for your truck. I purchased a heavy boat to pull with my F150 and could not believe how well this product worked. Installation was simple, first took 40 minutes the second took 20. If you are on the fence, do it. I promise its worth it. I don't ever write reviews and felt this product deserved all the shout out it can get. The ride quality was exceptional. This should be included on the stock truck!

No more saggy rear end!
The Timbren SES, works! Installed on a 2020 F-150 Ecoboost that tows a 8500 lb boat/trailer. I reduced my overall sag a total of 2" and retained a firm control while towing. The suspension system does not rest on the rear axle while not loaded so the regular suspension is unaffected (adding the spacers will cause it to contact the axle when unloaded if you're looking for a full-time solution). Install was generally straightforward and the instructions were clear. The only hiccup, a minor one, was that on the 2020's Ford added a hose-clip harness to the axle in the general area where you'd attach the mounting plate on the driver-side. So I had to cut a small notch out of the metal mounting plate (there's plenty of extra "lip" material) so it could fit on the axle with enough clearance to not rub on the leaf springs. Other than that, install was a breeze! I am extremely happy with these. They definitely do what they say and save you the extra cost of a totally upgraded suspension.

F150 install review
Honest review after installing them my truck bounce a lot without no trailer or hauling. For each bump it bounce an additional 3 times it’s a bit annoying. The pro about is it does work while towing or hauling. They never mention the extra bounce on any video or manufactured detail.

Great product
I have a 2020 F150 XLT and haul a 28ft/6,000 lbs trailer (trailer fully loaded). The stock truck would squat horribly when driving. After installation, the truck is close to level without being able to manually adjusting. It is an inexpensive way to level your truck and a whole lot easier to install than expensive air bags.

Great product for heavy toppers
Super easy install. Takes less than an hour with min tools. I just blocked the front tires and jacked the truck up on the rear hitch with a floor jack. Remove the bolt holding the factory bump stops and then install the timbren set up. I have a 17 f150 4x4 crew cab with the 6.5' bed and the max tow package. The truck is used for a contracting business in which I carry alot of tools, ladders, in a work topper and bed slide. The rear dropped about 2" with the added weight without towing a trailer. I used the supplied spacer also. This return the factory ride height and handling. I do not notice a harsher ride. I'm always on the bump stops now which may be different than people not always carrying a load. I chose this system over airbags due to the simplicity and maintenance free. Airbags seem to never hold the air pressure long unless you install an on board compressor system. The only negative I have found is the powercoating/paint was chipping off in the box. I'm not sure why they waist their time with such a cheap coating. I will have to spray paint them as the paint continues to fall off.

Bounce was increased
I paid for $269 for new but got a product that had been installed, I didn't pay for refurbished Update: now that they are installed and I have tested them. Does not work as advertised... actually did the opposite. They have increased the bouncing so bad I get car sick. Have contacted the company directly because the window for returning to Amazon has past. Company won't stand day any kind of return because we went through Amazon. Company said it's to bad. We are out $288 as I have to remove then due to them bounding the camper and truck so much it's like a rodeo when driving. It's actually not safe for how bounce it is. And yes they were installed correctly when not under load and the correct ones for our vehicle. I would not recommend anyone buy this product though amazon as the company said due to most people not being able to get them installed and tested out in a timely manner to return if not working right. This was a wast of hard earned money.

They work
Considered all the options on suspension enhancement for my F150, these work...Went with them because airbags would require continual adjustment. These have not effected the ride of my truck when not under load and take out the sag when it is....Easy install, did the job in 40 minutes

Bought these for my 2021 F150 heavy half instead of airbags after being so disappointed with the ride on my last one. Have been running for a month and wouldn’t go back to airbags for anything. A colleague runs helper springs (Helwigs) and also rides stiffer than me. Photos are taken when my payload is about “medium” with wooden coffin box packed with tools and a few hundred pounds of gear. The Timbrens are just off the plates and don’t usually engage until I add another hundred pounds or hook up to a trailer, or travel on rough roads. I’m just riding on factory suspension. Here’s why I recommend; -price point - cheaper than air bags and a good bang for your buck compared to leaf packs -install - 5 bolts per side, done in less than an hour with a basic socket set -ride - you don’t feel a difference from factory until you’re loaded. The Timbrens just hang out where your factory bump stops used to be, and when you’re light, they stay out of the way and don’t impact performance or comfort in any way. -performance - Once you’re loaded and they’re in contact with the plates atop the axel, you’ve got all the added suspension I’d be comfortable putting on a half ton anyway. Factory springs are still working, but now they’ve got the help and support where needed the most, and you don’t feel catapulted or bounced on every bump. Only thing I’ll say about install tips is that it’s way easier to do when you’re empty. Directions said to jack the frame up so your axel is hanging, but I was able to do just parked. Suspension was brand new with only 50km on it from the dealership, mind you. Will definitely go this route again in the future.
