Heavy front-end gear can make the nose drop and throw off handling. The Timbren Front Suspension Enhancement System adds 8,000 lbs of load support with two Aeon hollow rubber springs that replace the factory bump stops. They work with your existing suspension to keep your rig level, improve traction and steering, and make sure your headlights stay aimed right when carrying heavy weight or using front-mounted equipment.
Each hollow rubber spring collapses progressively along its folds, becoming firmer as weight increases. That means you get a smooth, cushioned ride when lightly loaded and strong resistance when the load gets heavy. The rubber construction also absorbs most of the road shock so bumps and rough surfaces feel more controlled while helping prevent bottoming out that can wear out your suspension over time.
Each spring works on its own side of the vehicle to balance uneven loads and reduce body roll. When you corner hard or swerve around something in the road, the independent action pushes back against sway so the vehicle feels planted and steady. It also keeps things level when a load sits off-center or equipment weight isn’t perfectly balanced.
No air lines, no compressors, no manual adjustments—just strong rubber springs and custom brackets that bolt to existing frame points above the axle. The kit includes vehicle-specific brackets and hardware for simple installation with no drilling required. Once mounted, the system automatically supports your suspension every time you load up without any extra setup or maintenance.

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
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.
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
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
For me surprisingly easy to install at 67 years old. Had immediate handling improvement and steering control.
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.
I received my 2nd order the Box was partially open again and one of the plates were missing I just need a refund
This is my 4th Ford set I purchase and install so, do you think I like them? If I ever buy another truck guess what I'm putting on it? Timbren Kits Front & Rear!!!
Great product and fantastic service!
Kit was used on 2025 Ford F 550 Install was easy enough, worst part was getting factory bump stops off. Had to use a little grease to keep washer in place before I started nut. Used the supplied spacer ended up raising front of truck a 1/2 inch without spacer it wouldn’t have been in contact with axel. Will adjust my review after I’ve hauled our camper a trip or two.
