When heavy gear like a plow loads up the front, your suspension needs help to stay level. The Timbren Front Suspension Enhancement System adds up to 1,800 lbs of support to keep your front end from sagging. The hollow rubber springs replace your axle bump stops and work with your factory suspension to stabilize handling, steering, and braking under load. With the truck level, your headlights point in the right direction and front tire wear stays even.
Each Aeon hollow rubber spring is designed with a convoluted shape that compresses progressively—the more it’s loaded, the stiffer it gets. That means you get cushioning and comfort with light loads and solid support when things get heavy. The rubber construction takes the brunt of bumps and rough surfaces, cutting down on harsh jolts and helping extend the life of your suspension components.
Each spring works on its own to handle side-to-side motion. When you turn sharply or carry an off-center load, the independent action helps control body roll and sway. The result is steadier steering through corners and less rocking when one side of the vehicle hits a dip first.
This kit includes two hollow rubber springs, custom brackets, and hardware made for a direct bolt-on fit in place of your factory bump stops. There’s no drilling, air hoses, or compressors to deal with—just bolt them on and go. Once installed, they automatically adjust as weight changes, giving you reliable, maintenance-free load support every time you head out.

Glad we had the right fit for you Tom! Where are you located, and how much snow did you get this last season?

I hear you, and that makes sense based on what you’re describing. If the Timbrens are in constant contact, they’re basically always engaged, which is why the front end feels so stiff instead of only firming up under load. You might actually be a really good candidate for SumoSprings part # SSF-281-47 (as long as your truck is a 2WD) They’re a similar concept but made from a softer, more progressive material, so they compress more gradually instead of feeling like a hard stop. That usually gives you support when you need it without taking away all the ride comfort like you’re experiencing now. Glad to hear the install went smoothly and the quality was there, that’s pretty typical with Timbren, it just comes down to how they behave on your specific setup. What were you mainly trying to improve up front, sag, handling, or just a smoother ride overall?

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.

I have upgraded towards trailing with my truck camper Artic Fox 990. I have not had the time to reach to etrailer for a solution with my 1998 Dodge 2500 timbrens installation. I have a new addition and will install the timbrens on a F-550 to have the same travel assurance...Pre trip test run to Key West early this winter... Anchorage 2024 Spring...Thank you etrailer

Still going strong. The ride is a little bumpy but when I tow the truck doesn’t feel “squishy” whenever I make my turns. I’m still super happy about the product.
