Best 2009 Ford F-350 Super Duty Truck Vehicle Suspensions

These keep my truck level with my slide in camper on board. It no longer rests on the helper springs. I have gained over 2” of height on the bed. Super easy to install. They also are noticeable on corners. Not nearly as much lean.

In stalled these on my 17' F350 SRW, & these work great if you haul a gooseneck for a living or haul any type of trailer. No sag whatsoever,but lose maybe like 1-2" of height when loaded. From the price, they beat having to install bags that will eventually need maintenance.

I don't really do reviews very often, but these things work extremely well, especially when you consider that they only take a few minutes to install and they are only blocks of rubber that are held in place by one bolt! I sprayed my factory stops down with WD-40 and pulled them out with some long needle-nose pliers wedged on both sides of the stop, between the frame and the rubber. I then glanced at the directions, figured out the stack-up I needed and installed them in less than 10 minutes! I'm not kidding! The best part is they work! They close the gap between the frame stops and the upper helper spring, engaging the spring right off the bat. I have an F350 dually with a Grey Wolf 840 that weighs 2400 ish pounds, and I haul a car trailer with a total weight of 6000 pounds behind that! These worked so well, I was amazed! These are the only suspension enhancement of this truck, too! You might need something more if you are hauling a very large camper or 5th wheel, but for me, this is all I am going to use!

Just installed the upper stableLoads on my 2021 F350 dually. It was an easy job. I used long needle nose pliers to wedge underneath the factory bump sticks. Then just leveraged them out. The ride of the truck is a little rougher with no payload. Planning on loading my northern lite 10.2 truck camper on in a few weeks. I believe this will improve the ride.

Installed these Timbrens on my 2016 F350 to enhance the stability of my truck for a slide in truck camper. Have loved the results of them. They have noticeably helped leveling the truck/camper combo, and sway while driving. When the camper is off the truck these are not engaged. Have had no issues and would recommend them.

We got these Timbrens for our truck that hauls a truck camper. Took the sway out of driving

Was able to install these with a 15mm flex head ratchet wrench and lifted the rear of the truck to make it easier. 30 minutes to take off 4 nuts and put em back on. 2 minutes assembling the timbrens with the added spacer. I have a f350 with a salter and plow. Loaded with salt the lights shoot up and in the snow ?? it’s like hitting hyper drive and you’re blinded. These helped big time. Very happy so far.

They may be a great product but they did not work on my 22 f350. Even with the spacers provided they would not make contact with the trucks axle even with a heavy slide in camper. If I am going to keep them I’ll have to make welding modifications to extend the bracket so it will work on my truck model pictures with and without the camper loaded. I would like to update my review to say that Timbren came through and made my application work by sending me the right parts so my truck doesn’t squat and it handles my truck camper much better. Timbren has great customer service

Overall very pleased with these air bags. I did add an on board air compressor to allow easy adjustment as I pull anything from a 16,000# fifth wheel, to a 10,000 car trailer to a boat trailer. The ability to adjust with the on board compressor just added convenience to an often used set of air bags.

Excellent service. Etrailer rocks. Fast delivery. The product is not installed yet.

The product was as advertised. Instructions were provided and fairly straightforward. Be sure to jack the frame up high enough to access the area where the airbags go. Be careful when inserting the clips into the frame. I had one that slipped and shot into the inside of the frame and thankfully I had a long handled magnet and retrieved it. One recommendation I have is for the manufacturer to preassemble as much of the product as possible which would minimize the chance of parts being assembled incorrectly. I mounted the valve stems on the bumper on each side of the license plate.

Tow 11,000 lb. FW witha Ford F250. Love the feel of the Air Lift airbags, and the insurance of the internal jounce bumpers if needed. Over 5,000 miles logged, and still going strong.

UPS delivered with packaging intact. L & R Wedges are wrapped separately and labeled. Hardware was contained in a sealed bag. 2 pieces were damaged, easily replaced at the hardware store. Instructions were reasonably clear, but there is room for improvement there. Installation : Installation was on a 2018 Chevy Colorado and straight forward. There is the option of installing the units inboard or outboard. Inboard installation on the Colorado would have resulted in insufficient clearance between the spare tire on the rear units, and the fuel tank on the front. Outboard installation resulted in minimal clearance with the mud flaps on the rear, and contact with the brake line and supporting bracket on the left front. Some backyard engineering with waterpump pliers was required to create adequate clearance. Use: Engaging the wedges is not possible with weight on the axle. The truck must be jacked up enough to unload the springs before rotating the wedges into position. I haven't had a chance to load up the truck and hook up the trailer. I'll provide follow-up when I do.

Installed StableLoads on a 2017 Ram 3500 dually that carries a 4500lb (wet) truck camper and pulls a 24' enclosed car trailer. The StableLoads are easy to engage/disengage depending on load, and have none of the issues common with airbags. In combination with a Hellwig BigWig sway bar, the truck rides well and handles well, even with the high center of gravity with the camper.

I needed something for my Travel Trailer (12k lbs), I have a Ford F250 and needed to level the truck with the Trailer hooked up, just about 2/3 inches. These Air Springs have worked very well over the past year, we took the trailer for about 4000 miles (Louisiana to Grand Canyon) in April/May 2023, the Air Springs worked perfectly...

Works great when pulling my 5th wheel RV. Truck now runs level and rides smooth

Having been in the auto/truck repair business for over 50 years, I thought this would be a good Idea so I tried it. I could have made my own but it would be a lot of cutting and drilling because it is so many pieces. I used it to add capacity so I could haul my camper that I purchased three states away and had to pick up. I used 2 of the 3 plates because there wasn’t enough room for three. It did very well like that but after I got back I added the 3rd plate figuring I could use the third one by just jacking the truck slightly before engaging. I thought all three woul be needed once the camper was full of water and gear. I am enclosing a picture of how ti drill the springs with using the vehicles own drill press (screw jack) for changing tires. I still need to test fully loaded and with all three plates in place.

This is the best towing improvement item I have ever purchased. We purchased a new 2018 Ford F-250 super-crew with the 6.2 gas and had our load leveling, anti-sway hitch professionally installed to tow our 2016 28' travel trailer. We towed the trailer for 1550 miles on numerous trips and it was very uncomfortable. At first I thought it was trailer sway, but soon realized it was the truck trying to point left or right or bouncing up and down every time we hit a dip or bump in the road, no matter how slight. It was truly white knuckle driving. I searched for the problem and solutions and decided to try the TorkLift StableLoad system. It was one of the best decisions I have ever made. We could tell within a few blocks from home the truck felt much more stable and on the highway it was like a different truck and trailer. We just towed the trailer 856 miles and it was an incredibly easy and relaxing drive. I love that I can engage or disengage the devices so we don't have a stiff ride when not towing. If I ever install one again I will have someone else drill the spring leafs or at least rent the tool from the manufacturer. I ruined the 2 drills they sent almost immediately by not using enough pressure and using too much drill speed. Once I realized what I was doing wrong I was able to drill the holes using a floor jack to apply pressure as others have described and drilling at the slowest speed possible. Once the holes were drilled it was very easy to assemble and install the StableLoads.

These bags are amazing. Make the rear end ride pretty rough so I put deaver add a packs from carli and did the day star buckets for the bags. Now they are connected when I need them, and disconnected when I dont. Pretty awesome set up. I've put 5200 pounds of rock in the bed of my truck, the rock yard thought I was crazy but then I aired up the bags. You should of seen their faces. Rode level, sat at about 85 psi and rode like a caddy.

Feels like a new truck!

I have a 2020 Ford F-250 Lariat FX diesel and I pull a 2022 Jayco Eagle HT fifth wheel with a GVWR of 10,995 lbs. I noticed when I was hooked up to my trailer and raised my landing gear the back of my truck would squat causing my headlights to shine somewhat into the sky and sometimes while traveling the interstate in construction zones the ride was rough. So I decided to add airbags. I chose the Air Lift Load Lifter 7500 XL Air helper springs(#AL55FJ). I had them installed by a local garage and he did a great job installing them. I love the end result a much smoother ride and the braking seems smoother also I can easily level off my truck with the 7500 XL Air lift system allowing my headlights to shine straight out now. I give these guys five stars. In addition to adding the Air Lift 7500 XL system I also had the Air Lift Wireless Air compressor System(#AL58WQ) installed and it is Bluetooth, compatible on my iPhone which is amazing. I can control the lift on my bags individually or paired together with the touch of my phone. No stopping and getting out in the rain or looking for an air hose. I can sit in my cab or get out and increase or decrease the amount of air in my Air Lift system. I can also do it manually if I so choose. In the photo you can see where I mounted the two air fitting on my crossmember right below the compressor on the frame. There were already two holes there so and can be accessed easily. I am very satisfied with my compressor system and I give this a thumbs up in addition to the five stars.

Great product, after a year's use practically every day the product performs as it should. Coupled with the on-board remote-controlled air compressor pulling multiple different trailers is easier than ever.

I install this for a customer that I have on the recommendation of etrailer as being the one that was necessary for this vehicle. On receiving the product was having problems as the truck was not set up the way that the illustration showed the truck was bought new by the original owner and had 50,000 miles and have never been modified spoke to fire stone about that at the recommendation of a trailer other parts were necessary, it turned out to be quite a mess. Mini phone calls hours of trying to make something work. The system failed at about 500 miles customer was very upset. I spoke to eat trailer no help at all referred me to fire stone no help at all. It was just to say the way things go sometimes and they were very sorry. I ended up having to give the customer his money back very expensive for me all the way around very poor recommendation on what I should’ve bought for this vehicle very poor product service by a trailer and fire stone both so end result after turning the truck back to stock, I haul the airbag system that I purchased to the dump

Worked great. Easy to install. I use them on my F-250 while pulling a 12000 pound fifth wheel travel trailer and had no issues.

Product works as it was supposed to, chose my own fasteners as the self tappers broke heads off, so I drilled and tapped into the frame and used stainless fasteners, compression was good and I like the mobile app on my iPhone

I just bought a new 2019 Ford F250 to pull my new fifth wheel. The pin weight of the fifth wheel caused the bed of my truck to drop a few inches so I bought the Air Lift LoadLifter 5000 Helper Springs and the Air Lift One wireless on board compressor to raise the bed back up to level. I installed all of it myself after watching the etrailer installation videos. I think somewhere they mention it being a 2-3 hour job. Well...if you do it every day, then it probably is. It took me the better part of a day to get it done. The first thing i did was remove the spare tire for easier access. I also tried to install the airbags without lifting the truck. Actually, I did install one side without lifting and it wasn't that hard. However, there is a nut on the bottom bracket that is between the airbag and the leaf spring that is impossible to tighten without lifting the truck body. Even after lifting the body, it was still very difficult to access/tighten. Instead of drilling a hole for the schrader valve, I used a couple of oversized washers and installed it in a hole on the hitch frame that was already there. The Air Lift One, I installed on the frame, on the drivers side of the vehicle and just forward of the gas tank. This is really about the only place on the frame without wiring of some sort. I got the EZ mount but didn't use the large U-bolt as I didn't find any place it would work. Instead, i just drilled a couple of starter holes in the frame and used the provided self-tapping screws. I also wired the hot and always-on wires together and directly to an upfitter wire under the hood. I had no trouble getting the wireless remote to communicate with the compressor and it works great. Now, with my fifth wheel attached to the truck, I can add air and level the truck back to factory heights. Overall, the install wasn't that hard and would have been super easy with a truck lift. The people at etrailer were great when made my order and will definitely give them a call again.

While these worked great for the first few months and helped level the load, they have now become deformed and squished out of shape permanently. We have a slide in camper that is on the truck for only for trips otherwise the truck is unloaded and off the bumps. I did not expect them to deform so much, and so easily after only a year of use.

Sumo Springs work great with camper. Much less body roll, firm but not stiff ride

Easy to install and great support from the manufacturer. These raised my rear by 2 inches, eliminated the sway at high speeds, and all but eliminated squeeky spring noise on my 2005 F-350 fully loaded with a truck camper.

Excellent product, have used before with very good results. Easy to install. Hardest task was removing the old bump stop...

So managing a travel nurse's life we tow all over the country.. The Sumo spring has helped tremendously with ride level and stability for tens of thousands of miles in this first year.. With no hassle of leaky air hoses or blown bags along your ride it is by far one of the easiest ways to help support your load!!!!

The Sumo Springs work great. I have a 5th wheel and the Sumo Springs really keeps the truck from sagging without compromising the ride.

Arrived as noted and in good condition. Instructions show 2 types of install. Turks with Bounce tongue stopper, and back section without. One the F350 2023 FX4 Dually model the drivers side lower bracket hits the aluminum that the block the fixed brake line attaches too. Called Firestone and I modified the bracket cut small notch off. To the DYI installer helpful note go ahead and assemble airbag on lower bracket when using spacer and start bolt. Compress airbag and I used Zipties to hold compression til I placed on axle. If not you only have 1/2-3/4” to try and get bolt started into airbag from bottom. After aligned then tightened all my bolts and torqued. Approx airbag install and running hoses about 2-3 hrs. And manual fill lines come with a no drill bracket that can be used on rear if preferred in addition to a compressor if purchased.

OK, so I love the way these work but I had issues with the printed instructions. They were not clear as to whether I needed to use the axle support bracket when I have the Jounce Supports. I installed the bags once with the axle brackets installed (and things just didn't fit well). I then looked up the online instructions which were different and clearer and indicated NOT to use the axle support brackets if you have Jounce Supports. So I had to remove and reinstall the airbags a 2nd time in order to get the bags to sit right and install tight to the Jounce Supports. I'd recommend having the Online instructions handy ILO the printed instructions that come with the kit.

Air Lift air springs are good and dependable, use them for the last 25 years on three pick-ups always worked great. My complaint would be against the lousy packaging which came with two or three holes and all messed up, luckily all that was missing was one washer.

I installed these air lift bags in a day. It was a lot longer than I thought, but it was in the middle of winter in an unheated shop and only basic hand tools. No hoist, so there were a lot of up and down trips with a creeper. Very good installation manual which made the process easy. Very happy with the purchase.

This product is very heavy duty and very well made. It is very simple to install. The service was great and was delivered earlier than expected. The experience was great.

I have not towed anything yet. I pull a 42' 5th wheel RV and from what everyone tells me, these bags make a huge difference. I'm full time living in an RV so I don't have a shop or all the tools that would have made this a bit more easy. First of all, unless you have a lot of time and patience, this is a tough job for one person. Do yourself a favor and get an air socket wrench. This would cut down on install time considerably. I don't remember the size, but if you have a dually like I do, have a set of ratcheting box end wrenches. Thankfully, the guy helping me had a set and I don't know how we would have done one of the brackets without it. Watch some youtube videos for some helpful hints. Go to the manufacturers website for videos. Read through the directions a couple times first. Especially pay attention to the specifics of Left and Right, and sway bar or no sway bar. The directions aren't horrible, but they aren't great either. Divide your hardware, put them in zip lock bags and label them, using the parts list in the front of the book. Also, have a breaker bar on hand. My buddy and I had never installed these before. Neither of us are certified mechanics, but have a pretty good understanding of mechanics and we know how to turn a wrench. This install took us about 6 hours (note, this does not include the hour or so that I spent putting the bags together on a previous day). To raise and lower, we used a bottle jack under the rear hitch. You don't need to raise it off the ground, but you need to get it as high as you can without going off the ground. I will try to come back and add my 2 cents on the performance aspect after we head out with the RV. As always, etrailer was very helpful and I had a speedy delivery.

I installed the air lift system and could not be happier. The truck now rides very smooth even with a heavy load. Great product addition to my truck.
