Specs:
Whether you're hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but more of the truck's weight, as well. Because less weight is on the front axle, the front tires are making less contact with the road. Overall handling - traction, steering, and braking - is negatively affected. But the resistance from Timbren's Suspension Enhancement System works with your factory suspension to keep your vehicle level and improve your driving experience.
The Timbren system has a custom-fit bracket that will be bolted onto each frame rail above the rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the spring sits, one inch above the axle. The inch of clearance allows the existing factory suspension to operate normally under light loads and standard terrain, ensuring the smooth, comfortable ride that you are used to.
Timbren Suspension Enhancement Systems are designed to work progressively. When the hollow rubber springs are compressed, the convoluted design causes them to quickly collapse along the folds. Once the folds are compacted, the stacked barrel shape increases resistance, stiffening the suspension and keeping the truck level.
Each hollow rubber spring works independently to support the driver's or passenger's side of your vehicle. This is helpful when you swerve or make sharp turns. Each spring is activated when it is needed, so body roll is greatly reduced. The independent action also works well when you are hauling off-center loads.
Because the vehicle handles better with the springs, less turbulence will be passed along to the trailer, and this helps to keep the trailer in line. Your driving comfort is further enhanced if the trailer does begin to sway (from a gust of wind or a passing semi), because the movement from the trailer is not transferred to the truck. This also works to make the sway subside more quickly.
Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall. Wear and tear on the factory suspension is also lessened because the rubber springs work to prevent bottoming out on rough roads.
Compared to the Competition
Timbren's suspension enhancement systems are much easier to install than air springs - there are no air hoses to run, no compressors or gauges to hook up, and no manual adjustments to make. The rubber construction makes Timbren's springs more elastic than similar products constructed of microcellular urethane. And more elasticity allows for a more comfortable ride because the rubber has more travel.

The system works well while under load with a gooseneck or bumper pull trailer, however when unladen the ride can be bumpy as there is not a lot of Gap between the leaf springs in the timberland rubber shocks. The system works for us because we usually haul with this truck. If you use your truck as a daily driver with no load an air bag system would give a more comfortable ride.
Great product there leveled the load and made tow way better.
Thanks
Steven - 12/14/2022Here are some pics. I installed the timbren could in about 20 minutes and put them to work the very next day pulling my LE3505 Weekend Warrior Fifth wheel. My 2012 F250 power strike was sagging horribly before purchasing these coils. The coils make the truck perform like a one ton & rides wonderful! Thanks for the opportunity to not have to install Air Bags!!
After one year the Timbren Rear Suspension Enhancement System has performed as
advertised. My 2016 F-250 does NOT squat with the fifth wheel trailer attached and the ride quality with trailer attached has also improved. Springs arrived quickly and took about 30-40 minutes to install. Excellent Product for towing!!!
Patrick G - 11/05/2018I read the recommendation to another buyer and decided to try this product on my 2012 Ford F250 Superduty. I needed help for my 25' goose neck trailer. EASY to install. Worked perfectly with 15K of hay + 6K of trailer weight. The rear of the truck barely set down on the factory overload springs. Empty ride does not seem to be affected as the Timbren pads do not contact the overload stops.
Thanks for a perfect solution without great cost and installation hassle!
Tom W - 07/20/2014The Timbren Rear Suspension Enhancement System was easy to install and works very well with our 5th Wheel attached. With no load in the bed of the truck (F250 Super Duty) the ride is a bit stiff, but with a load or with the 5th Wheel in tow the ride is very smooth and the Truck no longer dips in the back.
Took the dip out of my truck with 35ft travel trailer. Got smoother ride going down the road with less chucking. GREAT!!
Chuck - 08/02/2022Just installed these so haven't had a chance to put them to use. We have a 5th wheel RV and was told by a mechanic that these will stop the rear end sag and also help with any sway problems.
Also need to really give a big cheer for etrailer, very friendly and fast service! Thanks etrailer!
The Timbren rubber springs are a great addition to the truck 2013 Super Duty Lariat Crew Cab 172" 4x4. The truck has the 20" wheel option which requires the factory to place a 2" leveling block up front. That makes the truck level of course, taking away the rake, however in doing so makes it look like it's squatting when loaded. Before installing the Timbren springs I loaded the truck with a pallet of pellets and the wheel well sat at 38 5/16" from the ground. After the installation the same load was placed in the bed and the wheel well measured 39 9/16" from the ground. The Timbren springs saved over an inch of squatting meaning more weight on the front for steering and breaking. The ride improved from the motion of the ocean leaf spring ride while pulling our travel trailer to a more smooth but firm at the same time feel, a better ride than empty which does not engage the Timbren springs. This product is the fraction of the price of air bags and far less complicated/ less parts and things to go wrong. One of the original bump stops gave me a hard way but wasn't too bad. I installed the Timbren springs 19 March 2016.
I was undecided what I needed to replace the factory bump stops on my F250. Erica G. was very knowledgeable about my situation and steered me toward the product that I needed. Thanks!
After a year these suspension supports have been put through the ultimate test from pulling a 35 foot bumper pull RV and a fully loaded 28ft car hauler not to mention all of the landscape supplies loaded in the bed of the truck. In all the situations I absolutely had no problems with sag or sway. With no load my truck had the same ride as factory. Very pleased.
I have a 2015 Ford F250 Lariat, I pull a 7000 lb. travel trailer. I was led to believe that My empty ride comfort would not change, NOT TRUE. I have removed them.
Sierra K - 05/03/2022These may be a five rating, just put them on today so time will tell so I rated them a 4 for now, and the install was a bit of a pain as a result of short bolts. After installation, my F250 Super Duty 4x4 (no lift) has about ½” between the frame and the Timbren SES bump stop. Took me about 1.5 hours to install both sides. Taking off the old bump stock while not complicated was a bit of a chore. But a little muscle and time and they came off.
I did encounter an issue which certainly elongated the install time. The two bolts (long ones) that are meant to feed up through the bump stop with a lock washer through the internal bulb washer were “to short”! I tried and tried, I even smashed the lock washer down a bit and retried, no go. The bolts on either side would not thread unless the washer was off, so…I installed them without the lock washer. I’ll have to keep an eye on them I guess? Analysis…the two long bolts supplied are too short by about an 1/8th of an inch to thread into the Timbren SES frame assembly.
It took 3 hours from start to finish the old stops took the most time to remove once installed we went for a ride with the slide in camper it was amazing I would recommend it to others
Holds the truck level, and a bit smoother ride with the camper or a trailer on. So far they have been great!
It was easy to install. I haven't
Towed my toyhauler yet. But did read reviews and I'm sure I will love them.
I ordered the Timbren Suspension Enhancement Kit on Monday and received it on Wednesday with the standard shipping. (Free on orders over $150.00). This is the third order from etrailer.com and every order has been expedited quickly and received before date quoted. All my orders have been correct and good quality. I installed the Aeon Rubber springs on my 2013 F-250 4x4 Diesel in about 20 minutes just like the video showed. With my truck bed loaded with supplies and bumper hitch trailer hooked up, my truck bed is just a hair below level; before it squatted a couple of inches. The road test will be tomorrow.
I installed these on my 2012 Ford F250 because I have two friends who have them on their trucks and they pull a travel trailer and a fifth wheel camper. I was impressed with the difference it made compared to my truck and camper Parked next to theirs'. I am mechanic and I see no reason why anyone would have trouble installing these them selves. Clean off the Nut and end of bolts before trying to loosen. Spray some WD-40 on the threads. Put on some gloves and use a 15mm wrench to loosen factory nut. Be sure to hold up on the factory bump stop because it has a line up pin that keeps it from turning as you loosen the nut. The driver side is a little more aggravating to get to because of wiring harness but there's plenty of room to use a wrench first then a 3/8" drive rachet and short extension with a good 6point 15mm standard depth socket will speed up removal. Then installing the new parts is a breeze. Just follow directions or etrailer videos on YouTube. Took longer to remove factory bump stomps than to install new ones. Maybe 45 mins total on original ones maybe. Then after preassembly of new ones, it took maybe 20 mins to install completely. Give yourself 1:30 hrs of time and enjoy your truck not sagging around town when loaded.
Lance M - 06/08/2020They work great! Keeps my F-250 level when pulling my 37 ft fifth wheel. No more headlights shining in the trees.
Installed the Timbren stops as instructed. Total time was about 30 minutes. The installation would have been half that but one stock stop was tough to remove due to rust.
I'm very pleased with the looks of the installation, quality of the product and the service from etrailer. I'll report back next week after I hitch up to my 5th wheel but I do expect everything to be good.
I like the performance of this product. It has helped tremendously carring a loaded trailer. I haul 15,000 lbs on a regular basis.
Eric - 03/30/2019Product is as advertised. Not as versatile as airbags but not as much to go wrong with as airbags either. Nice compromise. etrailer was awesome from ease of finding product that fits my F250 to quick shipping and informative installation video.
Excellent quick shipping. The install on my 2013 F-250 was very straightforward and quite easy. Product seems very well made. Just as mentioned, they sit about 3/4 inch from making contact while the truck is unloaded, so does not affect the empty ride. I have not towed with them yet, and am looking forward to seeing how they handle the load.
I had thought I wanted air bags for my 2016 F250 but after talking to some friends I decided to give these a try. EASY installation, and they Work! My truck is not equipped with the factory overload springs and once I loaded my 7x14 dump trailer the suspension sagged a lot. Once the Timbrens were installed the truck sat much more level and drove a lot better! Highly recommend!
These rear SES bump stops were very easy to install. The driver side was a little more difficult due to the wiring harness on the chassis. I installed the at dusk going into darkness with a little light (that was free) from Harbor Freight. It only took about 30-40 minutes to remove the stock bump stops and to install the Timbren SES. I will be using to assist in hauling my fifth wheel camper.
