Heavy front loads like plows or equipment can make the front end sag and throw off handling. The Timbren Front Suspension Enhancement System adds up to 14,000 lbs of support to keep your vehicle level. The hollow rubber springs work with your factory suspension to stabilize steering and braking while keeping your headlights aimed right and tires wearing evenly.
These Aeon hollow rubber springs compress progressively, so they stay soft over light bumps and get stiffer as more weight is added. They absorb road shock and cushion rough terrain, helping your ride feel smoother when loaded. By taking the brunt of the bumps, the rubber also helps prevent bottoming out and reduces wear on your factory suspension.
Each spring works independently to support the driver’s or passenger’s side as needed. That means less body roll when you swerve, corner, or carry an uneven load. The independent action keeps the vehicle stable through turns and helps it stay level when one side is carrying more weight than the other.
Installation is simple with custom-fit brackets that bolt onto each frame rail—no drilling required and no air lines, compressors, or manual adjustments to deal with. Once mounted, each rubber spring stays in contact with the axle so it's always ready to cushion and support your suspension whenever the load demands it.

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
