When heavy equipment like a plow or front-mounted gear adds serious weight, the front end can sag, throwing off steering and braking. The Timbren Front Suspension Enhancement System adds up to 14,000 lbs of load-carrying support to keep the front of your vehicle level and stable. The hollow rubber springs mount in place of the factory bump stops and take on the extra weight as needed, so your suspension stays in its proper range without bottoming out.


Rough roads and potholes don’t have to rattle your teeth. These Aeon hollow rubber springs act like built-in shock absorbers, taking the brunt of bumps before they reach the cab. They let the leaf springs move freely under light loads but stiffen progressively as weight increases. The result is a smoother, more controlled ride with less bounce and less wear on your factory suspension.


Sharp turns or uneven loads can make a vehicle lean or sway more than it should. Each Timbren spring works independently on its side of the axle, reducing body roll when you swerve or corner and helping compensate for off-center loads. That means steadier handling through curves, crosswinds, or uneven terrain—especially when carrying heavy or uneven weight up front.

Installing front-end support shouldn’t mean a weekend in the garage wrestling with hoses and compressors. The Timbren system comes with custom brackets and hardware that bolt to existing frame points—no drilling required. With no air lines to run or adjustments to make, setup is straightforward using basic tools. Once mounted, the springs are always ready to engage automatically when the load demands it.

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.
The Timbrens take the bottoming out of the suspension away on rough roads. Also takes some of the sway away. Pretty easy to install.
A+++ Excellent product and customer service. Bought both front and rear suspension enhancements and worth it. Highly recommend.
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.
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
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.
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).
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
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.
For me surprisingly easy to install at 67 years old. Had immediate handling improvement and steering control.
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
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!
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
These bumpstops really work, they stop the front end vibration before it travels through the shocks and springs, for a smooth ride
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.
Front end kept bottoming out this took care of the problem. Ram 1500 mega cab
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

I year later and still happy with my Timbrens. Sets on the fronts of my 1997 Dodge Cummins 3500 4x4 and dads 2001 2500 2x4. Best money spent to keep the frontend roll and diving under control.Still highly recommend.
