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.

It help compensate for off center loads and will reduce body roll when swerving and turning corners. These springs have also actually stock absorbents taking the brunt of bumps and rough roads.

Review from a similar Aeon Spring System in Vehicle Suspension


this is the second set of Timbren springs I have purchased, the first set was on my Ford Raptor, they took all of the sag and sway out of pulling my boat. I have this set on my 2015 GMC Denali 2500HD, I pull a 42 ft. 5th wheel and the Timbren's take all of the sag and sway out, these are in my opinion the best product I have purchased for my truck. 683687

Review from a similar Aeon Spring System in Vehicle Suspension


Installed this on my 2009 Caravan because when I had a hitch mount 4-bike platform rack hanging off the back and was loaded with camping gear and family, the rear suspension was terrible, it would bottom out, and my headlights pointed up so that everyone would flash their brights at me. New shocks helped, but did not solve the problem. This product did fix the problem and I am very happy. I was concerned about the feel when the van us unloaded, but this has not been an issue. I highly recommend this product. 796869

Review from a similar Aeon Spring System in Vehicle Suspension


I first put the Timbrens on the rear to help stop bouncing and porpoising on highways and bridge ends when towing. The rears have a gap and do not touch the springs until the truck is loaded, working great and keeping a smooth unloaded ride. The front Timbrens fit snugly and touch all the time. The ride is firm and a bit harsh with my unloaded truck having a snow plow spring option. When my trailer 30 ft trailer is hooked up, the front of the truck is slightly lighter. Towing with the Timbrens is nice and the bounce and rebound porpoising is very controlled. I would like the front Timbrens to be a little softer when the truck is unloaded, but I think these units are a nice add-on for better control, safety, and preventing damages. I had the fronts installed at the shop when rotating tires and a front end alignment. The rears installed easily. 691475


Comments
They have worked out great when towing my 30 ft trailer. We took a coast-to-coast trip across the northern USA and into Canadian Rockies and excessive bouncing was controlled. I still would like the front to be a bit shorter and not always touching, so the unloaded ride would be less harsh.

After a 3000 mile trip with a 42' fifth wheel on a 2016 Chevrolet single rear wheel short bed 3500HD, I will say they made a difference. They took some of the bounce and the side to side rocking out of the truck. I would definitely put them on my next truck as well. 667565


Comments
Still good. The right solution is a dually with heavier springs and more stability from 4 tires, but that is not in the budget.

Review from a similar Aeon Spring System in Vehicle Suspension


I bought these as a replacement for "air bags" which I had two different sets, which failed over 10 years. i would say this product is helpful with pulling a trailer and lighter loads but from time to time I haul heavier loads and this product doesn't offer as much help/support as the air bags. This product is a little cheaper and if they don't weaken over time they will be a help. I have added additional leaf springs to two different pickups but then you end up with a stiffer ride full time. 421383

Doesn't get any easier for an install. A jack, some soapy water and a couple pieces of 2x4. In about 5 minutes you're done. Took out almost all sag when I dropped my travel trailer on the ball. Great addition to the suspension. 488109

Rear suspension pads work great. Ride is still like factory with no load unless driving over a big bump at high speed. When towing a 32 foot travel trailer the sag in back end of truck is greatly reduced with a lot more control. Easy to install. The downside is when truck is full with passengers and not towing anything the added weight makes the ride rougher. Shipped on time. 575558

I have a Timbren rear suspension system on my 1982 Chevy truck that I still own, and after 20 years they still work fine. This latest set installed easily on my 2001 F-250 and they work just as well with and without a load. 440182

Have not tested it out yet, but the installation took about 15 minutes by myself, looking forward to trying them out with my 28ft enclosed trailer. You will need a block of wood under them when you let the jack down to seat them in the cups fully there is no way you can snap them in by hand, the video had that great suggestion 199076

I ordered timbrens for the front and rear of my chevy 2500. I have a 2000 lb truck camper and I wanted something to help carry the load a little better. I had no idea that my front bump stops had worn away to almost nothing until I installed these. They have worn well and performed well so far. 628835

Review from a similar Aeon Spring System in Vehicle Suspension


I bought these for a 2012 GMC 2500 Duramax. The installation for these was much easier than I anticipated (I can't say the same for the front suspension system.) Just lift up your truck, pry out the stock bumper stops, line up the Timbren springs with a 2x4 underneath, and lower the truck. The weight of the bed/frame is enough to get the Timbren spring to seat correctly. This took me less than 10 minutes. Ride quality seems to have improved as big bumps on the road are less rough. These keep the truck from sagging underneath the weight from a trailer, too, though I didn't have much problem with that to begin. Overall, I like this addition. Easy. 48427

I purchased these to help with the squat on my F-150 when towing my 32--foot travel trailer. I need to tweak the setup on my WDH, but otherwise am very pleased. Without the trailer, you don't even know they're there. 558730

Excellent product! Went on in less than 10 minutes with a 15/16" wrench. Leveled the truck out under load and significantly reduced roll. Awesome bang for the buck. And etrailer service was spot on, as usual. 378049


Comments
I still think these are an excellent alternative to bags and very cost effective. My only complaint is that on my 15 Ram 2500 I have to switch out the extra spacers when I’m not towing heavy. The axle and Timbren spacers make contact when unloaded and causes a harsh ride. The good news is that the extra spacers go in and out in minutes I don’t tow heavy very often. With the spacers in I am able to pull a 43’ toy hauler with little roll and excess bounce, an the truck sits fairly level
