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.
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.
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.
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.
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.
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.

I put these on my vehicle (2018 4Runner) when I began pulling a trailer with a weight distribution hitch. They did their job in that the suspension felt firmer and the vehicle felt more stable. They also helped reduce the "nose drop" during braking that 4Runners a famous for.
by: Edwin09/18/2021
excellent upgrade to the stock rubber bumpers in my 2016 Lexus GX 460. The stock has a tendency to drift when hit with cross winds above 60mph. This Timbren front suspension enhancement eliminated that. The SUV is more composed even when driving on rough pavement. Cornering is more secure for a tall SUV such as the 460 with high center of gravity.
It's also easy to install. Jack up the vehicle until the rubber bumper clears the metal then unscrew it. Screw the Timbren in.

Long story short. Well worth the purchase and fairly easy to install (if you have the correct tool to remove the OEM bumpstop). I used an 18" pipe wrench to give me some leverage.
by: Brian 11/17/2019
Went on easy, and does what it’s supposed to do. Very little sag in the front with the plow hooked up. Before there was almost 6 inches of sag.

Review from a similar Timbren Aeon Spring System in Vehicle Suspension
I was back and forth between Timbren SES and airbags. Everyone in forums were very biased toward air bags and very opinionated on the Timbren SES. Yet I could find one instance in which someone tried the Timbrens, were dissatisfied and then switched to air bags. I called etrailer, Jamie recommended this product to me for my application. Installation on a 20-year-old truck had me nervous, I live in the Midwest and have a lot of salt. Installation was a breeze, and I have a B&W 5th Wheel Hitch (turnover gooseneck ball). This made the install a bit more challenging simply because I had a large bolt through the frame directly above my bump stop nut. If you do this install with the B&W Hitch, get a set of gear wrenches, or borrow a buddies 15mm and 9/16 wrenches. You need the 15mm to remove the factory nut and the 9/16 to install the Timbrens. I sprayed wd40 two nights in a row prior to installation to make sure I had good penetration of oil - I didn't break a bolt or a knuckle. I recommend installing the Timbren spring to the mounting plate, then install the mounting plate with Timbren to the truck. I didn’t need to remove my wheels or my spare, I jacked up the back under the hitch, used jack stands and let the weight of the axle separate the rear end from the truck giving ample room for the installation. After installation, I checked the clearance of the TImbren from the axle and had 1 inch of clearance. I installed my 1200-pound pickup camper and the springs just started touching the axle. I have a 21-foot fiberglass boat and seen about a 1/4-inch drop after I connected it to my truck. These things work and best part is – no maintenance and no danger of shifting weight if an airbag lost pressure or was punctured/damaged. I hunt with this vehicle and drive through thick brush and timber, I feel airbags wouldn’t hold up with the abuse I put my truck through. The Timbren SES system took the squat out of my truck and made the drop from the connection of my heavy boat hardly noticeable. Thank you etrailer, great experience as usual!

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
Comments
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
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

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.

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!

One of the timbrens appeared to be installed once and removed. Box said it was 2018 on it.
Comments
The second spring does look rough and I will have our Customer Service team reach out to you. I am not sure what the 2018 refers to however I know that it is not a manufacturing date. I checked and we have had recent stock checked into our warehouse. We do not have any remaining stock from 2018.

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

Review from a similar Timbren Aeon Spring System in Vehicle Suspension
Delivery was extremely slow and got the items late and the box came ripped up and all hardware was lost in shipping! I waited 4 days for the item and called them and they sent out all new hardware and had to wait another 5 days for the hardware. They really messed up my coming trip with my motorhome, I would not recommend this company to anyone, honestly the lousiest service you can get from a company! I do belong to several RV groups, I’ll let them know about the bad handling of my problem.

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.

- How Do Timbren Springs Install on the Front Axle of a 2004 Lexus GX 470We have not yet had the chance to install Timbren front suspension enhancement springs # TTOFTAC4A so we do not have a video. We do have the instructions which I have linked for you below. Installation is fairly straight forward. There are 4 steps: 1) Raise vehicle allowing the axle to hang freely. 2) Where four bump stops exist, remove the rear bump stop. 3) Mount Timbren assembly using existing holes and Timbren supplied fasteners. 4) Lower vehicle.
view full answer... - Will Timbren Suspension Help Level a 2007 Toyota FJ Cruiser That Has More Weight on Passenger SideThe Timbren suspension enhancement will replace the axle bump stops on your 2007 Toyota FJ Cruiser. They will work independently front and rear, and side to side. So, when you are carrying a heavier load on the passenger side of the vehicle it will compress the hollow rubber spring and become more rigid as the load is applied. This will help keep the vehicle from leaning heavily to that side. It will not affect the empty ride of your FJ Cruiser. The Timbren suspension has a weight capacity...

For the rear if it is 2- or 4-wheel drive use # TTORSEQ. I have included links to the instructions for both sets for you to view.

Since no air has to be added these kits simply work when they are needed and you don't have to think about them. For standard use you need part # TTOFTAC4A for the front and part # TTORSEQ for the rear, but if you plan on going off-road you need part # TABSTOF for the front and part # TABSTORSEQ for the rear.

What is likely happening is the weight of the trailer is pulling down on the vehicle and compressing the factory suspension so that there isn't as much space for it to travel up and down.
