LOVE these! I had a set of secondary airbags for towing on my truck, and they eventually wore out and needed to be replaced. I pull a fifth wheel, and I wanted something I know would hold up and be reliable. Enter Timbren. These soak up unwanted suspension sag and unmarked highway bumps like a champ. Fifth-wheel pulling is stable, and the rear end doesn't bottom out. 15/10 would buy again! It took me about 2 hours to install, including taking the old airbags out.

I will start be saying that I was thinking back and forth of buying the Airbags suspension system or the Timbeen Aeon Hollow Rubber Srings for months. There are numerous comments out there made in regards to both systems, and it comes down to each and every one of us to go for the best one that might fit your needs and overall desire bottom line, including of how much are you willing to spend in the end. However, I can tell that the Timbren it is NO brainer considering the fact that anyone can install these in less than an hour and then forget about it for the rest of your life, instead of a real headache installing the airbags suspension system and its air compressor plus the air lines too, drilling holes into your frame, etc...including the fact that you will ALWAYS have to check the air presser of these airbags and be always concern to inflate them every single time you want to tow anything that requires a lot more resistances or heaviness. Bottom line, it is going to be a pain in the neck since these airbags always loose air pressure after 1 - 2 weeks as far as i heard many people complaining about it. Installing the Timbren rubber springs then these are good for ever, no maintenance, no concerns, no adjustments necessary at all. Not to mention that these Timbren Aeon Rubber Springs are cheaper or at least half price, compared with the airbags system’s price. Also keep in mind that the Airbags do have the tendency to get permanently destroyed at some point in time and therefore you will need to replace one of them or both after a while, since they might become useless. The Timbren are rated up to 8600 lb, and these are a lot more reliable than the airbags without any doubt. Now, in regards to rough ride since some buyers mentioned and complained about the Timbren Rubber Springs, saying that these are notorious for it. Therefore, please keep in mind that IF you DON’T install the extensions that the package comes with it for both (left and right) sides of the vehicle, then you WILL eliminate the rough ride of your travel as many people point it out having it with the extensions mounted, instead of having these extensions NOT added to each side.. I will estimate that you will have about an inch left in between the Rubber Springs and the rear axel without the extensions mounted on each side. So, I strongly recommend, that you DON’T install the extensions unless your vehicle was lifted previously. However, I did not lift my vehicle, so I installed my Rubber Springs on a factory stock version of my vehicle. I just want to add also that I still have around the same amount of space left on both sides of the vehicle after I already installed my Rubber Springs, considering that I have a little more weight added to my truck since I kept the 5th Wheel hitch assembly as usual and a chest box that is full with a lot of other heavy crap totaling to at least another 250 pounds for sure combining, including myself being a guy of over 220 lb too.. I also heard other people saying that taking any pothole, then you will feel the difference and noticed immediately that these rubber springs are the reason for it. Honestly, I drive mostly in town and highways my truck, and I have not noticed yet any of that rough bump unless you might take a little bigger pothole I would assumed or bouncing significantly while going through some deeps or uneven roads perhaps. Installing these rubber springs it was fairly simple and I did NOT raised my vehicle from the ground at all, and also kept the tires in place without removing these since I considered to have enough space to work around. So far I am happy with the Timbren system, and I am GLAD that I did the purchase, saving a bunch of money by going this route instead of the airbags. Anyway, I purchased my Timbrens specifically for my 5th Wheel RV 37ft long as well as being over 13500 lb loaded, having also over 2100 lb hitch weight, therefore I am trying to eliminate any sagging or bounce while traveling with my RV hooked up, including avoiding as much as possible any rear springs failure just in case. I am also planing to trade in my RV in the future and get something bigger and heavier, which will allowed me right now to increase the hitch weight to even over 2500 lb as the truck was rated for from the manufacture. Well again, it is up to each and every one of you to decided what fit your budget and needs in the end. Best of luck with your purchase no matter what that might be. I hope that my comments will help. M. 12.03.2017 2017 Ram 2500 HD 4x4 Diesel Laramie.

This is my second set of the Timbren DR2500D SES. The first was on a Gas RAM 2500. I traded it for a 2020 RAM 2500HD Diesel powered. Since I pull a heavy RV I bought a set of these for the new truck. As it's been said in other reviews the left, drivers side, is easy to install. I didn't use the spacers that come with the kit to ensure I had clearance between the bump stop and axle after installation. The passenger side is a little harder because of getting access to the rear bolt because of body parts being in the way. What I did was put some blocks under my trailer hitch and put a floor jack on top of the blocks. I jacked up the rear of the truck as high as I felt comfortable with without lifting the wheels off the ground. This gave me a lot of clearance to install the passenger side bump stop which is needed. On this side I installed the mounting plate before I installed the rubber bump stop to the plate. This allowed me to access the hole in the mounting plate to easily tighten the rear bolt (see the product pictures). Eliminating the problem with body parts interfering with tightening this bolt. To mount the rubber bump stop onto the plate I had to make sure I could get my ratchet and extension out of the bump stop after I installed it. To do this I used an extension and socket combination that would fit inside the bump stop to tighten the bolt to the plate and just clear the bottom of the bump stop where the ratchet connected. With the rear of the truck raised I had the clearance under the rubber bump stop to disconnect the ratchet and remove the extension and socket. I put blue locktite on all the screws prior to installation. All bolts are tight and secure. After removing the jack and letting the rear of the truck down I checked the clearance under the bump stop. I could get my fingers under both sides. This must be about 1/2" or so I expect. I was satisfied with the ride during the test drive after the install. It rides good with that amount of clearance. When hitting normal bumps in the road I could tell the Timbren were installed but it wasn't bad. Larger bumps though were definitely felt. In summary the ride isn't bad unloaded and well worth it. From previous experience with the other truck I know the ride and handling while pulling the Travel Trailer will be greatly improved. I recommend these. The only negative for me was the shipping. These were shipped in the original box with a shipping label placed on it. One side of the box was split open. They barely survived the shipping. I would suggest to the seller that they either reinforce the box before shipping or put the box into a better shipping container.

Put these on a Dodge 2500. Sis not use spacers so there is a gap between the bump stop and axle. Rides like stock when unloaded. When I hook my bumper pull travel trailer up it stopped the bounce when going over large bumps. Helps with sway and I loaded a full yard of gravel in the truck and it helped while going around corners. Simple, passive and inexpensive compared to other options.

I want to give this a five star review but the biggest issue I have is that when you have no weight on the back and you hit a bump it does make the ride a little stiff. With my fifth wheel camper on the back of my truck, it’s great. It doesn’t sag and there’s a little spring to it. Other than that, it’s really great if you can handle the jarring when you’re empty. I definitely recommend not putting in the spacer. That puts these on the axles all the time and that could get really bumpy.

Why did you pick this product vs others?: I'm going to start by saying I took 2 stars away because when I got the item the original package box was WET and crumbling. It was obviously wet when it was shipped because they placed the wet crumbling box in a plastic package then boxed it up and labeled it. So since it was sealed in plastic or didn't get wet in transit. All Items were included and it went on my truck fine. It takes a little more time to put on the passenger side than driver's side. All in all it installed as it should, fits nicely.

I am very impressed with the ride quality & performance of this product. I was going to spend three times the price of this product to install a nice air bag system however this is as good or better & there literally is no potential for failure like an air bag system. I highly recommend this item for people using their trucks to haul or pull heavy loads.
