When the bed is full or the trailer tongue drops your rear end, these severe-service rubber springs step in. Sitting above the axle, they add up to 7,000 lbs of support to keep your ride level so steering, braking, and traction stay where they should. The progressive rubber design gets stiffer as weight increases, so light loads stay smooth while heavy ones stay controlled.


Rough pavement and uneven work sites can beat up factory suspension. These Aeon hollow rubber springs absorb road shock and cushion impacts so you feel fewer jolts through the cab. Acting as a buffer between frame and axle, they help prevent bottoming out on bumps and extend the life of your leaf springs and other suspension parts.

Each spring works on its own to support the driver or passenger side as needed. That independence cuts down body roll when you swerve or take a sharp turn and helps balance off-center loads like campers or tools on one side. The result is a more planted feel that keeps both tires gripping evenly through corners and during emergency maneuvers.


Unlike air bag systems with hoses or gauges, these replace your factory bump stops using custom-fit brackets that bolt directly to the frame rails—no drilling required. The setup sits about an inch above the axle so your stock suspension handles normal driving, then the Timbrens engage automatically under load. It’s a straightforward upgrade you can bolt on with hand tools and get back to hauling.
Designed for service trucks with slide-in campers or in-bed salt spreaders, these heavy-duty rubber springs hold up under constant use without air leaks or maintenance. Their elasticity gives more travel and comfort than microcellular urethane versions, keeping the truck level and stable season after season of towing and hauling.

Ratings & Reviews
After reading some reviews on how bad ride quality became I was a little hesitant on this purchase. Knowing I had to do something, I pulled the trigger and I am incredibly glad I did. Installation took me literally 10 minutes. I took out original bump stops, installed one side and put a wood block underneath to "press it in" when I lowered the jack. It worked perfectly. I jacked it back up, removed block and repeated on the other side. The ride quality when unloaded is unchanged (except when you go over a really big bump). I have even towed my camper with them in now (7 hours worth) and they're fantastic! I would recommend to anyone!
I was looking for something for my 2016 Ram 1500 to level out the ride when pulling my travel trailer 33'. I considered the different types of air bags as I had success with them on my Ford. However the installation on the air bags is lengthy. I read up on the Timbren Suspension Enhancement System and decided it was worth a try. The installation says 15 minutes and that is not a joke. All you need is a floor jack and a couple of 2x4's. It took 15 minutes including getting the jack out and put back. Then I hooked up the trailer and the ride height is perfect, it also improved the overall ride when towing. Great product!
Received item 5 days after ordered. Arrived in original packaging in good condition. Very easy install took me about an hour. Key for me was use of 2x4 for final seating.
FAR BETTER IN THE WIND!
24 foot trailer with eight distribution hitch on a 1500 truck is not bad until it gets windy. I white knuckled a 45 mile drive to the dyno in March with a racecar in 20mph wind. That’s not uncommon. But my truck and trailer didn’t like it.
This product increased the stability by 5 to 10 times.
Highly highly recommend. Super easy to install.
Reduces squat too.
The Timbren is larger and stiffer than the stock suspension cushion. When empty the truck feels normal. It makes my dodge ram 1500 feel more like a three-quarter ton truck when I am towing my travel trailer. There is much less bounce over bridge approaches and less sway. When I loaded the truck bed with mulch the truck rode level rather than having the rear sagging The Timbren was very easy to install I inspected them recently and they appear to be in almost new condition I have recommended it to my friends for towing and carrying heavy loads
Easy to install, fits directly into the factory mounts. We occasionally carry a truck camper on our 2014 RAM 1500 and these bump stops support the weight and make for a smoother ride than air lift suspension. When the camper isn't on the truck, the ride is as smooth as with the original factory bumpstops.
I am pleased with the performance as far preventing trailer weight to affect the overall tow height of the truck. However, it does change the overall ride of truck when it is not loaded or towing a trailer. I am currently looking for other options.
These definitely beefed up the suspension for my towing. I don’t have the sag that is did before with the stock parts. Have had them for a year now and no complaints from towing a small enclosed trailer to my RV.

Still holding up strong. Keeps me from having any sag while towing. I tow a small enclosed trailer and our RV. Still going strong.

Equilizer E4 weight distribution hitch
Before installing the Timbren I experienced 5 inches drop even with the E4 hitch. Towing in a 20 mph cross wind was difficult above 55 mph, 18 wheelers sucked me over as they passed. After installing the Timbren I had a 2 inch drop, cross winds are much easier to handle and there's hardly any suck when a truck passes.
I've towed the trailer 1500 miles so far on the Timbren. They are easy to install on the Ram and worth every penny they cost. Thanks Etrailer for once again giving me great advice and saving me lots of money by not buying air bags. These work just as well, are maintainence free and far cheaper than air bags.
Product arrived faster than expected and took literally 5 minutes to install. I purchased these for support and stability under load of a 7x14' cargo trailer but have not yet tried this out. 5 stars for delivery and installation.

After a year these have proven to be a great upgrade to the rear suspension of my 2020 RAM 1500. They provide the support and stability needed to haul a 7x14 motorcycle trailer. Ive recently recommended them to a friend with a 18 Raptor and so far are working great for him.
These are the way to go. Airbags are nice but I never have to worry about leaking lines or bags. My Ram 1500 lowers two inches with the horse trailer gooseneck. Ill never go back to bags. Thanks Guys

The timbres suspension is still working great. I have had no suspension or breaking issues. The rear is a little more sturdy than if I had airbags but that’s what I wanted and it’s great not having to worry about air adjustments or leaking bags. Works great for me.
The product was delwith an open box with contents falling out. Produck itself is perfect and of surpurb quality.
Super easy to install legit just poped out poped in no lift needed just crawled under and 5 mins it was done.
Works great so far ill find out when my 30foot foot campers hooked up but for a 16foot trailer with a rzr and quad up on it it did its job.
Not 5 stars because i think this is a 150 to 175 priced product
It awesome fixed my sag problem
Good product! This solved my "sag" and loss of front end control while towing. Much cheaper than buying a new truck...I did get more negative feedback from road conditions but got rid of the bounce from weight moving off and on the front axle. Picture is from before installation.
2019 ram 1500 classic and help stop sagging by 2 inches with fully loaded Lance 650 on top
Very easy to install, just got them delivered today and now they are installed. Which took like 15 minutes total, didn't drop the spare tire , but the rear tires was removed since I bought new tires at time of installing them. I think I made a very good investment. Thank you !
Very satisfied with your product. Was very EZ to install, appox 20 minutes, and that includes setting my jack up. I've sent 2 pictures. The yellow is original bump stop, black is the new ones. Thanx again
Probably the easiest install I have ever done on my 2019 Classic Ram 1500 Warlock. Took less than 10 minutes and outcome is excellent. I can already tell the difference with the Decked tool box I have in my truck.
I have not had a chance to tow yet, but the install was very easy, and the ride without a load is almost like stock.
So far the easiest install I have ever encountered!! Took 15 only because I had to move jack to otherside otherwise in under 10 minutes. I have yet to place trailer on truck, tomorrow is the big test, we'll see how it handles.... huge difference from old one to these, so I expect a huge improvement....
works great easy to install would recom end
Excellent upgrade for 2019 RAMs hauling heavy payload or trailers. Must have rear suspension improvement from OEM bump stops. I've used Timbren on 2013 and 2019 trucks with great results. I will continue to use Timbren on my trucks in the future.
Easy install...these Timbrens are simple and they work well. I tow a small fifth wheel camper with my Ram 1500, and the coil spring suspension needs a little help, and these Timbrens work well.

The Timbrens are working very well. If I go to get some horse grain or some other medium weight load and the go over a rough patch, speed bump, etc., I can feel them bumping against the frame. I dont think that this is objectionable, I still like the simplicity and performance of the Timbren system.
They are difficult to seat. Soapy water does nothing to help. I had to spray with silicon,jack up the back of the truck and place 2x4's between the bump stop and the axle,NUMEROUS TIMES.
Once I towed my 5th wheel I noticed the difference. When unloaded, the ride is normal.

To be honest this is something that we heard with Timbren springs. I noticed that these springs are a heavy-duty spring that are best suited for trucks with slide-in campers or an in-bed salt spreader. Is this what you have? If you are towing quite a bit, then I would recommend considering an air bag system. The air bag system will be in constant contact with the axle which will give a smoother ride. They are going to be a little more expensive then the Timbren springs. The part number that I recommend is part # AL57375. The fit tips for it is that drilling will be needed, it does not fit with the factory Air Suspension system, special tools will be needed, it is compatible with in bed hitches, and it does not fit TRX models. You may also may consider a compressor system like part # AL57375 so that you have access to air on the go.
