Features to know about

Keep the Front End Up and Level: 15,000-lb Suspension Support

Heavy gear like a plow or front-mounted equipment can make the nose dip and throw off handling. This Timbren Front Suspension Enhancement System adds up to 15,000 lbs of support to keep the front end level and stable. The hollow rubber springs work with your factory suspension to improve weight distribution, steering response, and braking control under heavy loads without needing air hoses or manual adjustments.

Smooth Out Rough Roads: Hollow Rubber Springs That Absorb Shock

Bumpy, uneven roads are tough on your suspension and comfort. The Aeon hollow rubber springs take the brunt of road shock, softening impacts so your ride feels smoother and more controlled when loaded. By cushioning bumps and reducing harsh jolts, they also help extend the life of your suspension and prevent bottoming out on rough terrain.

Stay Steady in Turns and Crosswinds: Independent Spring Action

When you swerve or corner hard, each spring reacts independently to keep the vehicle balanced side to side. That helps cut down on body roll and sway so the front end feels planted through curves, crosswinds, or uneven loads. Even when carrying off-center weight, the springs automatically adjust to keep things level and confident.

Install It Once and Get Back to Work: Bolt-On Design with No Air System Needed

Adding real load support doesn’t have to be complicated. This system uses vehicle-specific brackets that bolt onto each frame rail above the front axle—no drilling required. The springs stay in constant contact with the axle so they’re always working, and because there are no compressors, hoses, or gauges to manage, it’s a simple install that’s ready to go when you are.

Video Transcript for Review of Timbren Vehicle Suspension - Towing/Load Leveling - T48SR

Hello, everybody, this is Jeff at etrailer. Today we're gonna take a look at the Timbren Front Suspension Enhancement System. Now, this is a custom-fit part, it is designed to fit the 2016 and newer Ford F-650 and F-750 trucks. And on a custom-fit part like this, I do like to recommend for you to go to our website, use the fit guide, put in your year model vehicle, and it'll show if this will work for your application. Now, heavy gear, like a plow or a front-mounted equipment on your truck can make your nose dip and throw off the handling. This Timbren system right here can add up to 15,000 pounds of support to keep the front end level and stable.

They're hollow rubber springs that'll work with your factory suspension to improve weight distribution, steering response and braking control under heavy loads, without needing air hoses or manual adjustments. The bumpy, uneven roads are tough on your suspension and comfort, so these Aeon hollow rubber springs are gonna take the brunt of the road shock, softening any impacts, so your ride feels smoother, more controlled when loaded. And by cushioning those bumps and reducing the harsh jolts, that's also gonna help extend the life of your suspension, prevent bottoming out on rough terrain. So also when you swerve or corner hard, each spring is gonna react independently to keep the vehicle balanced side to side. This will help cut down on body roll and sway, so your front-end field's planted through those curves, crosswinds or uneven loads.

Even when carrying off-center weight, the springs are gonna automatically adjust to keep things level and confident. It will include everything shown here on the table. It includes the two Aeon hollow springs, the two custom-fit brackets, the hardware to install it. Nice set of instruction, describe how it all goes together. Now, this system uses vehicle-specific brackets that are gonna bolt onto each frame rail above the front axle.

There's no drilling required. The springs will stay in constant contact with the axle, so they're always working. As we mentioned, the capacity is 15,000 pounds. Now, Timbren springs are not gonna increase your vehicle's weight-carrying capacity, so you still do not wanna exceed the manufacturer's recommended weight limit. Now, if you do have any other additional questions regarding this part or any other item we carry, please feel free to reach out to us so that we can help get all of your questions answered for you.

But that is gonna do it for a look at the Timbren Front Suspension Enhancement System.

15,000-lb Capacity. Great for trucks with plows, these front hollow rubber springs help to stabilize and level your vehicle. They also provide a more comfortable ride by absorbing road shock and improving roll stability. Easy to install and use.

by:

I watched installation videos for my FFF 53 Timbren suspension parts three times to familiarize myself with what I was going to be doing. This did help. I would say you need a little bit of experience in working on cars or trucks. This is a straightforward job with no fabricating needed. The hardware was correct. The instructions were correct. The parts fit great. I did this installation by myself. Another set of hands wouldn’t hurt but not necessary. If you’re on the fence on buying parts from Timbren, I would say go ahead and place your order.



by:

In addition to the rear I installed front Timbren suspension improvements. With the “Safe T Plus” steering damper also installed, the ride was such an improvement from the white knuckle eyes bulging ride before. Test ride on a very windy day with cross winds I barely noticed. The rough road also made little impact. I could not be happier.

These Timbren’s were very easy to install. Between front and back it took an hour 1 1/2 hours. Did the job at my storage lot with a right angle battery impact driver, breaker bar and wrenches. Lowered the leveling jacks enough to make room.



by:

I haven't had a chance to install the plow on my Jeep to see how this works, but installation was super easy (aside from getting the old bolts from the original rubber axle bumpers out).

Installation instructions say to re-use the original hardware, however my box included new bolts which is awesome since the old ones were pretty rounded after getting them off.

Once the old bolts were removed, installation only required a few wrenches and a rubber mallet. Assembling the rubber "spring" to the mounting bracket took a little ingenuity - the bolt that holds them together is JUST short enough that I needed to insert a washer sideways in my socket to be able to push the bolt enough to engage the threads in the bracket, then it was easy.

Mounting the assembled unit to the Jeep was easy - just put the first bolt partially into the frame then slide the unit under the head, then you can adjust the alignment and put in the second bolt. I used the rubber mallet to get the rubber "spring" to sit on top of the axle and align it so that is was directly above the axle. Then just tightened the bolts, and done.

I used 1 box end wrench and the rest sockets. The first bolt that goes in sits just above the round flange on the bracket so a socket won't fit. The second bolt is easily secured using a socket.

I hope this gives my 1993 Wrangler YJ Jeep the extra strength to support my plow - I am taking the plow off of another Jeep (same basic model) which had leaf springs that got SQUASHED and actually reversed (frowning face rather than happy face) so I'm hoping these suspension enhancers will prevent this from happening.

Less sway, much more enjoyable ride!



by:

I have a very heavy "Cattle Guard" on the front of my RAM 3500 and this combined with the heavy 4WD and diesel engine the extra support from the Timbren Front Suspension Enhancement System definitely keeps the front suspension from bottoming out.



by:

The bump stoppers are solid and the directions for installation were clear, even for DIY. The Ford F53 chassis for the Entegra Emblem is challenging to navigate. We found two sets of hands worked best. And installing the bolt from the top of the frame with the washer and nut below worked best.



by:

The Timbrens take the bottoming out of the suspension away on rough roads. Also takes some of the sway away. Pretty easy to install.



by:

A+++ Excellent product and customer service. Bought both front and rear suspension enhancements and worth it. Highly recommend.



by:

I like using Etrailer because i can call and talk to a person. These front ones went in pretty easy just like directions said. and they got rid of the bad bumping sound in my front end after hitting a bump. smoothed things right out.



by:

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:

Installation was not too hard, Install Videos explain all steps in great detail. BumpStops arrived in excellent condition and was delivered in a timely manner



by:

I had a problem with getting front sumo springs relative to the rear sumo springs I purchased earlier; however, the staff at etrailer were very helpful in getting me a suspension enhancement component made by timbren which I just installed. I believe the timbren supports are going to do the job I was looking for and make me just as happy as I am with the rear sumo springs. You will notice from the photos the supports make direct contact; however, the pictures were taken on a unlevel surface and when the truck is on a level surface the direct contact is equal on either side. Also, the timbren supports provide substantially more weight capacity in the event I choose to haul my scooter on the front end of the truck. Thanks again Derek S and etrailer staff I am very pleased with the service, customer relations and professionalism experienced when ordering my parts. Thank you, Bobby (Louisiana).

I installed Timbren’s front and rear on my 2020 F53 chassis motorhome. They are by far the best suspension upgrade I have done. I had previously installed Super Steer Trac Bar, Radius Rods and Safe-T-Plus, which had helped, but not as much as I had hoped. The Timbren’s finalized the package and it drives good now.



by:

Easy install, didn't even need the brackets for my application. Really helped with sidesway in the wind and seems to help the front from dipping with extra weight. Haven't tried plowing snow yet but I think they will make a major difference



by:

Ok it’s been a year since I’ve had the springs and I’m impressed. With how easy the install is and what you get out of it these are truly amazing. No more “squishy” feeling when towing my 22fy travel trailer. The ride is a little bumpy but I don’t care. I’m glad I found these.



by:

For me surprisingly easy to install at 67 years old. Had immediate handling improvement and steering control.



by:

Have them on several trucks now and couldn't imagine running snow plows without anymore.



by:

The front Timbren are working very good.The rear not so good



by:

Install was straightforward. Hardest part was getting the old bump stops out. Sway was greatly reduced on the Interstate and the rock and roll by passing semis was greatly reduced. Wish I had bought these sooner!



by:

Pretty pricey but well worth it. Put these all the way around at the same time as new rear leaf springs on our c7500 topkick and it made a huge difference. It's a top heavy bucket truck and it would rock and roll just turning a corner to the point it was downright scary. Now thats greatly reduced. They also smoothed out the ride especially when loaded more than I expected.
Install was simple, perfect fit. Worst part was grinding out the rivet on the old bracket



by:

These bumpstops really work, they stop the front end vibration before it travels through the shocks and springs, for a smooth ride



by:

I haven/t installed them yet. I think I should have gotten a discount for the age of the "box"s the Timbrens were in. May be a credit ,, Brad



by:

I love these things. They are worth the upfront expense. I have them on two ¾'s, one ½, and a minivan for road trips. This particular set is full-time active up front. I have a 2" leveling kit and I'm in em no matter what. Zero complaints though. Solid performance through all aspects. I don't run any front-end attachments.



by:

I have a 2006 Kodiak 2 wheel drive. Timbrin firmed up the front end to much. There in full contact with the spring. I think it to stuff and I might be removing them. The install was straight forward. Parts are as expected and quality of Timbrin is great. Just not enough cush..



by:

Great ordering, shipping time, cost, and supporting information. We added a snow plow and the product did everything as advertised.
