Most Popular Extra Heavy Duty for 2009 Ford F-350 Super Duty

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.

The original timbrens were much too stiff and resulted in the elongation of the hitch pin holes. I opened a line of communication with Timbren had me make very specific measurements, and sent me replacement springs (shorter). I have not installed them yet (and have not found need for them). In my opinion these are only appropriate for heavy, permanent loads such as a slide in camper or welding setup and such. I would not recommend them for periodic loading applications of less than 50% payload capacity on a 22 F350 SRW Timbren customer service was excellent

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

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.

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.

A year ago, I added Timbrens to my '09 F350 to help carry a '09 Lance 915 camper. Since my truck is a CC LB diesel model, the truck payload and loaded weight of my camper are similar. I found the Timbrens a cost effective way to limit the suspension sag and improve truck/camper sway. When unloaded, I rarely notice the Timbrens as they are ~1.5" away from the spring pack stop and only engage on large bumps. I also like the maintenance free aspect of Timbrens. To further enhance the loaded ride, I am replacing the thin factory contact pads on my overload springs with larger ones. I found that adding the Timbrens limited suspension travel such that it prevented adequate overload spring engagement with the factory pads. The replacement overload pads from Torklift and Supersprings are 3" (too much IMO as they contact the overload spring nearly all the time making for a rough ride). I am cutting down a set of Superstops to ~1.5 - 2" for the right amount of overload spring contact and Timbren engagement but still maintaining unloaded ride quality.

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.

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.

Giving 4 stars because of packaging box had holes in it and all brackets were just thrown in box I bought these for my 2018 F250 to pull 42ft sundowner toy hauler. They work great install little confusing on which way to slide them but there enough videos to figure it out. I wasn’t going to buy compressor at 1st but glad I did. We took 1st trip in it this weekend and being able to adjust air for tanks empty to full is nice. Even riding with no load seems to ride better Contact me few months down the road and let’s see how impressed I am

These air springs kick butt! I carry a heavy truck camper on my F-350 and they can handle that and more. In addition when it comes to leveling at a campsite I can typically do so without a problem (I have an onboard compressor with remote which helps with that.). I’ll never come close to the capacity these airbags can handle but they are a solid addition to my HD suspension.

Shipping was fast. Install was easy (once I removed the spare tire). Just follow the guide step by step. I haul 8000-10000 pounds in a 14 foot dump quite often. My truck would squat 6-7 inches. NOT ANYMORE. With about 65 psi I have a level ride. Much better handling. Great product. I should have bought years ago.

Great product! Works as it should, Instructions could have been a bit more detailed.
