Reduced axle sag with Timbren suspension enhancement

Just like the rear of your vehicle will sag under the weight of a fully loaded bed, the front of your vehicle will sag when under the burden of heavy equipment such as a snowplow. In this case, the front axle is handling not only the weight of the equipment, but also more of the vehicle's weight. Overall vehicle 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.


Install diagrams of Timbren hollow rubber springs

The Timbren system comes with custom-fit brackets that are bolted onto each frame rail above your front axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down so that the bottom of each spring touches the axle. Because each spring is making constant contact with the axle, it is always working to cushion and support your factory suspension.


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 increases resistance, stiffening the suspension and keeping your vehicle level.


Timbren suspension system works to prevent body roll

Each hollow rubber spring works independently to support the driver's-side 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're carrying off-center loads.

A snowplow mounted to the front of the truck will require extra suspension support for the front axle.

Timbren's Suspension Enhancement System will help raise the front end of your vehicle when you're using heavy equipment like a snowplow. This ensures that your headlight beams will be pointed in the right direction and tire wear will be reduced. If the plow is off-center or has an extension, the springs will automatically compensate for this as well.

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 because the rubber springs work to prevent bottoming out on rough roads.


Timbren Suspension Enhancement 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. More elasticity allows for a more comfortable ride because the rubber has more travel.

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


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


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!

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

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.

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


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




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.

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.

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


Installed these with only one issue, which was on the driver side rear axle. The axle had a ABS sensor cable bracket on the axle that need to be readjusted and trimmed down. The BumpStock was hitting this bracket on one edge. So actually, it's not and exact fit. But this issue is really a FORD placement issue of that cable. So just be aware that some extra work may be needed to install them. Passenger rear side install perfectly. Next is the drive to see how much better the coach drives, heard great reviews on that

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.

Worked great on our 2019 Honda Odyssey Elite to the East coast.Fully loaded with 4 people and a car top carrier,the Timbrens kept the van stable and level.
Sold the 2019 but took the Timbren system out and put them in our new 2022 Elite. Very easy to install, highly recommend.

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 will say they are perfect for towing but when your not towing cause they are so close to the bottom it feels stiffer when not towing! They should make long enough so that it touches besides that these are perfect

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Too early to give a ride review but I received the TFFF53B fronts and the TFRF53A rears for my 2019 Fleetwood Southwind 35K while at a campground this week. Easy enough to change out while there. It is about.a 2 hour job to change out all 4. The front right took me the longest and you have to reuse the existing bolt. A washer should be provided because the hole in the bracket is almost as large as the bolt head. I will be placing a large flat washer there. The rears took less time to change.. I used the first and third slots in the mounting brackets and they actually put the unit more over the center of the axle than the original bump stops. Same was true in the front. No clearance issue or interference with my trac bar.


Comments
Have had these on my RV for over a year nowhere and I am completely satisfied. The fact that these always maintain contact with the axles greatly reduce body roll on turns and uneven roads.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Couldn’t be happier with way they operate. I haul a 12,000lb 5th wheel trailer and helps tremendously with the handling and keeps my vehicle from sagging in the rear. Great idea and very reasonably priced.


Comments
Excellent, use them on a regular basis and still holding up great. They’ve been a great addition and also had a couple relatives add them to their vehicles.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


I really like these Timbren bump stops. I think the best thing about them is the simplicity, both how they work and how easy the install was. I bought these when I added a dump insert (similar to a salt spreader) into my 2019 F-250. I have loaded this truck heavy before with dirt and the truck sagged tremendously and had a lot of body roll. To prevent this with the now added dump insert, I installed these. Super easy to install! Took maybe 30 min. It reduces body roll and seems to improve the ride depending on how loaded the truck is.

One unfortunate consequence to the install is that the Timbrens brought to light that I have a weak leaf spring on my passenger side, which was suspect previously.

Overall, I'm very pleased with this purchase and would buy again!

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Highly recommend for anyone towing. Leaf springs were flattened out prior to install. Swapped the bump stops out for Timbrens in a campground before making a 1000+ mile trip home. They work amazing leveled the truck out while towing and absorb the bad bumps.


Comments
I would absolutely buy the Timbren SES again if I didn’t already have them. No issues after a year.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension


Ok, the drivers side was very easy to install. Maybe 15 minutes. The passengers side was another story, the rear bolt was very difficult to get at and took a great deal of time and creativity to get the bolt tight do to no room to turn the wench.
That being said it did improved the ride a great deal with no load, I drive country roads that are very rough , it completely stoped the wheel hop and provide a much better ride.
I would recommend installing these I’m glad I did! I would give this 5 stars if it were not for the passenger installation.

If your front suspension is worn to the point where it's only sitting one inch off the bump stops, the vehicle will be sitting on the Timbrens once they're installed, and the ride at the front suspension will be pretty rough. I'd recommend replacing your front leaf springs first. If your suspension still...
