An example of sag on a truck's rear axle under a heavy load. The Timbren Suspension Enhancement System levels the vehicle.

When hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear of the vehicle 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 vehicle's weight as well. Because less weight is on the front axle, the front tires are making less contact with the road. Overall vehicle handling - traction, steering, and braking - is negatively affected. The resistance from Timbren's Suspension Enhancement System works with the vehicle's factory suspension to keep the vehicle level and improve your driving performance.


Diagram of the Timbren spring installed

The Timbren system has a vehicle-specific 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 you are used to.


Animation of a standard Timbren rubber spring

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 provides increased resistance, stiffening the suspension and keeping the vehicle level.


Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's or passenger's side of the 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 hauling off-center loads.


An example of a trailer swaying

Because the vehicle handles better with the springs, less turbulence will be passed along to the trailer helping 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 passing of a semi) because the movement from the trailer is not transferred to the vehicle. This also works to make the sway subside quicker.


An empty truck on a bumpy road without Timbren

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 as 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 - no air hoses are needed to be run, no compressors or gauges to hook up, and no manual adjustments necessary. The rubber construction causes Timbren's springs to be more elastic than similar products constructed of micro-cellular urethane. More elasticity allows for a more comfortable ride because the rubber has more travel.

These work well enough, but they seem to be made for several applications (Toyota pickups, Jeeps) and they are a little long for my 95 Toyota pickup. Truck rides on them constantly, they just barely touch. This makes the suspension when unloaded quite stiff, they are supposed to leave a little gap so the vehicle rides on it's own suspension when unloaded.

For towing, they're great. For heavy loads, they're great. If I didn't have a cap on the rear, maybe they would have more of a gap. Oh, and the rear springs have 44K on them, this isn't a clapped out beater truck with 300,000 miles on it, the Timbrens are just a hair too long.

Would buy again.

Great product, installed it yesterday. Stiffened up the ride and really made a difference when pulling my utility trailer. I would really recommend this to any one who has an older truck.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


The hardest part was the de-installation of the factory bump stop. Installation of the Timbren’s was simple and easy.

My truck is 2008 F250 V10 Crew Cab 4x4 with factory overload springs. I have a B&W fifth wheel & gooseneck hitch installed. I did notice the difference in towing my 34’ fifth wheel trailer. The ride and handling was improved. I would recommend them.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


About a 1/2 inch difference in gap at the bump stop perch but still within parameters. Truck sits perfect with trailer attached. Haven’t towed yet. After towing if they perform like they should will upgrade to a 5 star. Easy to install, definitely needed 2x4 and jack. 2011 Silverado ext cab with 30 ft Genisis 5th wheel.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


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 see what youre saying here. From the photos, it looks like you have everything set up the way it should be. 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.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Haven’t had it on long, but so far so good. 1999 F350 dually. Bolted up nicely. Total job took 10 minutes. Have hauled two gooseneck loads of hay and truck drives SO much better. Nice and level. Money well spent so far.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


The Timbren rear suspension enhancement system helped with the truck swaying side to side when the slide in camper is on the truck.
The photos show right and left rear with Timbren’s installed (2 photos), with slide in camper on the truck (2 photos) and when the camper was removed (2photos).

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I installed Timbren on front and rear of Georgetown motorhome. The install was easy and the improvement in overall handling was noticeable. No more bottoming out on bad roads, and a reduction in sway or lean in and out of turns. Worth the money, especially in conjunction with my other bolt on upgrades. Safety steer, Rear sway bar, and Rear trac bar

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I have used Timberns on 2 other vehicles, a Toyota 4Runner and an S10 Blazer with out complaint.

I transport RVs as a contractor for an RV transport company. My truck is 2021 Ram 3500 crew cab, 6.7 diesel.

Because the weight of the units is different with each unit I haul I wanted an easy, no maintenance solution to maintain as level a ride as possible. I haul both bumper pull and 5th wheel units. In addition to the weight of the unit I'm hauling I can carry 110 gallons of fuel with both the factory fuel tank and my auxiliary tank. Additionally, there is the weight of my Curt 25K 5th wheel hitch, Curt 14K equalizer hitch and bars, and approximately 300 pounds in tools.

I don't have to worry about airbags not inflating. The suspension settles about an inch before making contact with the Timberns. Squat while loaded is negligible. The ride empty is the same as it was before installation. The ride loaded is smooth and controlled even when hitting large bumps at highway speeds.

Installation was simple and straightforward. It took me about a half hour.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Went on fairly easy, jacked the rear of truck up pulled out old bump stops,soapy water on new ones positioned them and with the help of two short pieces of 2×4s under each side lowered the truck, they slid right in place. Very easy. Won't be hooking up to 5th wheel for a couple of months, looking forward on how they work on truck squat. Might follow up then and give another star.


Comments
1 year later, they work as advertised, kept rear of truck at a more level stance, also a very smooth ride with very little bounce over rough highways. I would highly recommend.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Great product, it works perfect on my truck. Sometimes I tow up to 30k lbs including my trailer and my truck stays level. No more high beam flashing in my eyes from drivers going in the opposite direction on the road.




by:

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


They definitely support and did lift my 2014 toyota tundra up about 1.5 inches.
This application with my weight has trunk riding on the cushions all the time.
That has teavel and bounce issues that do make some driving situations interesting.
I may go ahead and replace with airbags but for now support things well!

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I used this on my Isuzu tow truck. The blocks in and of themselves are fine, they support the weight. Here's the problem: They are pre-loaded, meaning that they always touch between the frame and the rear axle. As you load the vehicle this puts more pressure on the frame in this 5" area where the blocks are. The springs have not yet taken as much weight as they normally would. Now, all this upward pinpoint pressure bends the frame. This is what happened to me on my rollback tow truck. After many hours and now double plating the frame all is well again, but a tremendous amount of work. Yes, the blocks are fine, but the result of installing this product resulted in a bent frame. The vehicle was not overloaded and was within the GVWR.

I have reached out to the manufacturer who will be reaching out to you.

Makes my truck feel better while towing a 5th wheel camper, especially over expansion joints of the expressway.

Very simple to remove and install. I took all of 15 minutes without even removing the wheels




by:

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I think I will be very happy with the ride when I tow our fifth wheel, it definitely needed the extra support especially on rough roads.I chose not to use the spacers because I like the softer ride when the truck is unloaded.




by:

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


2022 Ram 3500, 30 minute install time, great product. Hooked up camper without sway bars and only squat 3/4 inch, where before 4 to 5 inches. Recieved product in 3 days with etrailer staff sending me numerous emails. Great job to etrailer staff. Thanks

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


After a year on the road, and a few thousand miles of towing our 5th wheel, the Timbren bump-stops work great. Had air bags that required tinkering and always needed to adjust the pressures. No adjustments needed with Timbren.
Pros: Easy to install, no adjustments, adds stability while towing heavy loads.

Cons: Unloaded, makes driving over seriously large bumps a bit rough with only about an inch or so of factory suspension travel.




by:

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


The timbrens actually did what they were suppose to do. However, once I starter driving out west I notice the timbrens were riding on the axle which cause the speedometer to jump around depending on the road. I would recommend them if you are hauling or towing a camper or RV. I was going to contact etrailer about maybe removing a spacer for one set however the other set came as one unit. The bottom line is the Timbrens does stabilize your load for safe travels. I will be contacting etrailer soon to assist in correcting the problem...Road trip from Idaho,Colorado,Wyoming,and Utah were beautiful... Thank you etrailer

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I’d seen similar products rated in the 4,000 lb ratings but I went with these. I’m not a mechanic but I removed the factory bump stops and installed both these in 30 minutes or less. I used my rolling jack and lifted from the drop hitch and easily removed the old ones and soapy water and 1/4 twist and these were on. Placed a block of wood in the space between these coils and lowered the jacks then pressed it with my tractor to confirm full engagement. I carry a lot of tools on a 2020 Chevy 2500 I do feel a bit of butt bounce on large bumps but other than that I’m very pleased.




by:

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I haven’t hooked up to the fifth wheel yet or else it might be a 5 star. Based on the 15 minute installation time and the price compared to air bags this appears to be a logical way to go. I will update this as I hook up and put a load on it.
