Features to know about

Keep the Front End Level and Steering Sharp: 6,000-lb Support for Heavy Equipment

When you hang a snowplow or other heavy gear off the front, the extra weight can make the nose sag and steering feel light. The Timbren Front Suspension Enhancement System adds up to 6,000 lbs of capacity to help keep things level. The hollow rubber springs sit right above the axle to give instant support and prevent that front-end dip. With the truck sitting level, your traction, steering, and braking stay consistent and your headlights stay aimed where they should.

Smooth Out Rough Roads: Rubber Springs That Absorb Shock

Rutted streets, washboard gravel, or uneven pavement can beat up a front suspension fast. Each Timbren hollow rubber spring cushions the hit before it gets to your factory parts, soaking up bumps and rough roads so you feel less jarring through the wheel. The design lets the leaf springs move freely on light loads, then stiffens up as weight increases, keeping the ride comfortable whether loaded or not.

Stay Stable Through Turns and Off-Center Loads: Independent Spring Action

When you swerve or corner hard, body roll can throw you around. Timbren’s springs work independently on each side so they respond only when that side needs extra support. This keeps your vehicle planted in curves and steady when carrying off-center loads or uneven equipment setups. You get less leaning in turns and better control through quick maneuvers.

Install It and Get to Work: Simple Bolt-On Setup

No hoses, compressors, or adjustments to worry about—just bolt it on using the included brackets and hardware. The springs replace your axle bump stops on the frame with no drilling required. Once mounted, they’re always in position to help your suspension handle heavy work without any extra setup each time you use your equipment.

Video Transcript for Feature Breakdown: Timbren Front Suspension Enhancement System

Hi everybody, Andy here with etrailer.com. Let's take a brief look together at this Timbren front axle suspension enhancement system. Now, this system has been designed to fit your 2019 and newer RAM 2500 and 3500 with the four wheel drive and then your 2019 and newer Ram 3500 cabin chassis with the two and four wheel drive. On custom fit parts such as these springs, I do recommend taking advantage of our vehicle fit guide here at etrailer.com. Simply input the year make and model of your vehicle and our fit guide will confirm if this will work for you or if we have something comparable that will work for you. So just like the rear of your vehicle, how it 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 the snowplow.

and 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 all negatively affected, but the resistance from these timber and suspension enhancement springs are going to work with your factory suspension to keep your vehicle level and improve your driving experience. Now, these 6,000 pound capacity springs are going to give you additional support as needed, so you always have a smooth, comfortable ride. They allow your leaf springs ample movement while cushioning light loads, and they won't affect the empty ride of your vehicle because they become more rigid as more weight is added to them, increasing stability and providing great performance while hauling heavy loads and reducing vehicle sag. These are going to work independently, adjusting side to side, helping compensate for off off center loads and reducing body roll when swerving or turning corners.

And these springs also act as shock absorbers, taking the brunt of the bumps and rough roads extending the life of your vehicle suspension. So this kit includes everything that you see here. You're gonna get these two Eon hollow rubber springs, and then the vehicle specific mounting brackets here, the mounting points that you see here. And there's not going to be any drilling required for installation. Instructions are also included to guide you through the installation process.

And again, the capacity of these springs is 6,000 pounds. However, it is important to note that these Timbren Springs will not actually increase your truck's weight carrying capacity. So you do wanna make sure that you're not exceeding the manufacturer's recommended weight limit, and these do have a limited lifetime warranty from Timbren. Well, I think that's gonna wrap up our brief look today. I do hope that our time together was helpful for you.

Again, my name is Andy. Thank you for joining me.

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:

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



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:

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:

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).

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 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:

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



by:

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



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:

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.

Seem to be of good quality. Time will t ell.

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