When you hang serious weight up front, like a plow or heavy equipment, the front end can sag and throw off steering and braking. The Timbren Front Suspension Enhancement System uses a pair of Aeon hollow rubber springs rated for 14,000 lbs to keep the front end level and stable. They mount directly above the axle to take on heavy loads, working with your factory suspension to keep traction, steering, and headlight aim right where they should be.


Rough pavement and bumps can wear out a suspension fast. These hollow rubber springs soak up road shock and vibration before it reaches the cab. The progressive, convoluted design collapses smoothly under load to cushion impacts, improve roll stability, and prevent bottoming out. The result is a more comfortable and controlled ride when you’re loaded down or driving over rough ground.

Each rubber spring works on its own to support either side of your front suspension. When you corner or hit an uneven surface, they respond independently to cut down on body roll and sway. Even with an off-center load or a plow extension hanging out front, the truck stays balanced and predictable through turns or crosswinds.

There’s no compressor, air hose, or gauge to mess with here. This kit replaces your factory bump stops and bolts straight to the frame using the included vehicle-specific brackets and hardware—no drilling required. Once installed, the springs automatically engage when needed and don’t require any maintenance or manual adjustment. It’s a straightforward setup that gives long-term support without extra equipment or tuning.

All ready noticed a major difference in handling, and I haven't finished the rear suspension upgrade yet.
Easy to install, keeps the front end up with the snow plow on our 2500 Silverado
I had a little problem with the web page. So I called etrailer and Greg helped me with my order. So now I understand their web site better and will purchase more product in the future. Thanks! Mike
helps hold the truck up with a snowplow on
Highly recommend spending the money. My last pickup I bought Sumo Spring rubber stops and they seemed squishy to me, where these are hard and hold up very well. Holds my Boss V-XT 8'2" up where it needs to be. Don't go cheap! You'll regret it!
Put in my plow truck, went in super easy. Gave back stock ride hight with the weight of a all steal v plow.
My one-ton is a 2008 Chevy Silverado. As I drove with my 5th wheel I knew it needed some help. The folks at etrailer were great to suggest what I needed. Sure I still have bumps, but not as bad.
They seem to work, not impressed
Timbren SES heavy duty jounce bumpers dramatically improved the ride of my Chevy 2500HD and it drops only a very small amount when I hoist the plow. Less than 1/2" dropbin ride height with the plow raised. Yet the riee is not harsh. Excellent product, wish I knew about it years ago.
I have owned and used these over a year now. They honestly still look brand new. When recently I changed my upper and lower ball joints all I needed to do with these was to clean off the dust and dirt. I used my vehicle with these installed most off road and in the woods and they hold up very well and so far 4x longer than OEM!
Works very well in the front of the truck. Made the truck sit 1" higher. Supports the snow plow well.
Works great on my 2005 2500hd towing my 42 ft fifth wheel. Have them on the back also. No suspension sag and no sway,very impressed.
Fit was correct easy install. Just as good as air bags.

East install and my truck rides much better and carrys my plow much better. A must for 3/4 ton GM trucks in my opinion.
I am impressed with the timkens. Got a 2009 GMC 2500 hd and Western 8.5' v plow. Nose dive was an understatement before. However I put a 2" leveling kit and installed the timkens at the same time. One of them made my truck ride horrible. Probably the leveling kit from the torsion bars being turned in. I do notice tho that empty going over a jarring bump you can feel the timkens hitting hard. But with a plow on the truck it is the way to go. After this winter I'm gonna take them off and put stok back on for the summer. It's one bolt to replace them install was a piece of cake.
Not installed yet. Overpriced
Installed this on my 2005 Silverado 2500HD with the 8.1l engine. Easy 1.5 hour install with hand tools. Raised front of truck about 1" with constant contact with rubber. I'm installing a Boss V Snow Plow and a Truck bed Camper ( for Summer) and needed the extra weight capacity without the suspension sag. Ride quality degraded some, but is not objectionable. Ride is OK for a truck. This is a better solution than changing to stiffer torsion bars or cranking up the stock bars for my application.
i have used the timbren 4 different times for chevy front ends they are a must have if you use a plow

all 4 are still doing very well thank you for a quality product
I put them on all of my pickups
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.

Still working great. No problems. Really happy I didnt waste the money on airbags.
My 03' Chevy Silverado really benefited from the installation of the Timbren bushings. Shipping was fast the instructions from E-trailer were very helpful and made it easy to DIY. The front end of the truck seemed to be sagging especially when the plow was raised even with 600 lbs of ballast. The front end was raised up about 3/4" after the install and the ride quality is greatly improved overall. I cannot hardly wait to try them with the plow. I would highly recommend Timbren bushings to anybody with a higher mileage vehicle like mine 160,000.

These will be going on every truck I buy from now on.
this is the 3rd replacement of bump stops for my 99 chevy 3/4 HD 4x4. Two were OEM , and one an after market ( lasted a week ! ). I am impressed that the Timbren bump stops are well made and were a direct fit. The truck sits about an inch higher in the front end and best of all the ride is smoother . the truck also has new up graded shocks and the over all condition of the suspension is very sound. the shocks were installed prior to these new bump stops. I would give 5 stars however I am waiting this out to see what the Timbren bump stops are capable of in a year from know. my truck spends most of its time on road not off road .

I would buy again . these are worth 5 stars.
Out of the box fit !!
Only issue I had was keeping the wedge from moving during installation

Even after a year everything is still intact with no issues
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).

The timbren springs are working out better than expected. I installled new Monroe matic RV shocks front and rear on my 2006 Chevy Silverado 1500 just prior to putting the timbrens on the front and the sumo springs on the rear and the ride is great especially with a load or hauling my travel trailer and the ride is just as smooth empty. I highly recommend the timbren and sumo springs because they fit by application and there is nothing additional to buy. Thanks etrailer.

It still works great and looks good. A good bump stop is the best thing for ride quality in my opinion. It’s a more progressive spring rate that practically anything else.
