This SES Suspension Upgrade fits the front or rear suspensions. Timbren engineered their hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs the harder they work to prevent rear end sag. Whether you’re pulling a trailer or carrying a heavy load in the bed of your truck, Tiimbren's hollow rubber springs adjust automatically to keep the vehicle level at all times.
This SES Suspension Upgrade replaces the jounce stop on the frame. Its unique design ensures superb ride quality – loaded or unloaded. (There should be a 1/2” to 1-1/2” gap between rubber spring and axle to ensure unloaded ride quality.) Unlike other auxiliary spring systems, the SES Suspension Upgrade guarantees the best of both worlds.
If you tow moderate to heavy loads this will change the experience. While a little pricey for "just a piece of rubber", zero adjustments necessary and as good as airbags.
5.0You'll be glad you did
These improved my 04 1500 4x4 immensely! I have several hundred yards of gravel driveway, and these made it possible to push a light plow. Even unloaded, the truck handles and corners much better.

5.0Quick, easy and effective
Took me about ten maybe fifteen minutes to install these with my son.

5.0Easy to install and less than a full air bag setup
Very easy to install and handles the load of our 5th wheel much better. The truck does not squat as much and bucks less on the highway.

4.0Eliminates rear squat when trailering
Was a little harder than expected to get the timbrems installed on my RAM 1500. No observed effects on everyday ride. When 6500 lbs trailer attached the previous rear squat was gone. On smooth roads no negative ride effect. Do get a rougher ride on washboard road surfaces.
5.0Easy to install and works with load
Put in a 2018 2500 Silverado to pull a 7k trailer. Works well and really didn't notice any difference from stock when empty. Hitting speed bumps is definitely harsh but so what. Cheap and easy over airbags.

4.0Works as advertised.
These were not to bad to install, the passenger side was more difficult. I did not use the provided spacer. They also do not make the truck ride any rougher. They leveled the truck perfectly. I have a 2019 40ft 5th wheel and it corrected the squat of my 2019 Ram 2500. I was hoping that it would stop the bouncing while driving on residential streets but it really had no affect. It is probably has to do more with the short wheel base truck than the suspension.
