Heavy front-end equipment like plows or mounted gear can make your vehicle nose down, throwing off handling and headlight aim. The Timbren Front Suspension Enhancement System adds 4,000 lbs of load support through hollow rubber springs that replace the factory bump stops. They work with your existing suspension to keep the front end level, improving steering, traction, and braking under heavy weight so your setup stays balanced and safe.
Every bump and rut sends a jolt through the suspension when the weight’s up front. Timbren’s Aeon hollow rubber springs act like built-in shock absorbers, cushioning impacts and reducing harsh bounce. Their progressive design compresses easily at first for comfort on light loads, then stiffens as weight increases to maintain stability. The result is a smoother ride when loaded and less wear on your factory suspension.
Uneven or off-center loads can twist your suspension and cause sway through turns. These springs work independently on each side of the axle to handle uneven pressure and reduce body roll when cornering or swerving. That independence keeps your handling predictable whether you’re carrying a centered plow or gear that sits off to one side.
Installing load support shouldn’t mean tearing into your truck. The kit includes two custom-fit hollow rubber springs, vehicle-specific brackets, and all hardware for a straightforward bolt-on setup—no drilling or airline routing required. Once installed, the springs automatically engage as needed with no manual adjustments or maintenance to worry about.
Ratings & Reviews
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.
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).
Have them on several trucks now and couldn't imagine running snow plows without anymore.
The front Timbren are working very good.The rear not so good
I would say that the product is a bit pricey for what it contains. The secondary bolts came with the wrong sized nuts. Other than that, they work well to support the suspension.
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!
These bumpstops really work, they stop the front end vibration before it travels through the shocks and springs, for a smooth ride
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
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
Super simple installation that took about 20 minutes. These made a HUGE improvement on steering control and bounce. Driving on the freeway is a breeze. I highly recommend this product.
It good but one side with no bump had to be put spacer but the spacer was flat so the bolt did not have a lot of thread so I grind the spacer a bit so it could stay flush otherwise this might solve the problem of outter tire wear that ford transit has will find out soon
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.
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..
Great ordering, shipping time, cost, and supporting information. We added a snow plow and the product did everything as advertised.
So far so good
Works well. Pain to install but does the job. Don't attempt to install without air impact
Great product and easy to install as per the directions that were included. I would recommend them to anyone in need of this kind of product for your truck.
Install was easy
Directions should relay that the smaller piece of hardware goes into the frame but past there all is great. Just waiting for the snow to fly to really test the strength of the product with the plow on.
Great product...etrailer answered all my questions about installing this bump stop. they made it very easy to install. thanks again George J.
Great product and has helped with increasing the lifespan of my front suspension. I'm able to plow much easier now knowing that isn't going to hit the ground when going down the road to my next house.
Easy to follow directions. Quality material, but difficult to do solo. Definitely try to have an extra set of hands to assist.
I purchased the TDF15004B and TDR1500DQ products for my 2016 Ram 1500. Towing is way better and overall handling is improved. These products installed just fine. The directions were clear and concise. Etrailer has a helpful video series as well. Thanks to the staff at Etrailer for the great customer service and follow-up.
