You need a suspension enhancement system that will help your vehicle to safely tow and haul.
Microcellular polyurethane products are a great alternative to a traditional air bag system because no one wants to air up or air down every time they hook up a trailer or put something in the back of their vehicle. But even though they’re a great alternative to oldschool air bags, they come with 2 major flaws:

1) the material
2) the design

“Microcellular polyurethane” is the technical term that’s different from the term you and I use. The term we use is foam. Microcellular polyurethane is just the technical term for foam. It’s the same material used for foam mattresses, the sponge in your kitchen, even the foam fingers you see at a baseball game.

But who wants to put foam underneath their truck? Let’s be honest, we don’t trust that it will do us any good. We don’t trust it to keep our vehicle safe and level when we’re hauling or towing.

There is a product that doesn’t require any air and isn’t made of foam.

The Timbren SES suspension enhancement system is a major upgrade from air bags and foam products. Why? Because Timbren SES upgrades use patented Aeon® rubber spring technology purposely manufactured to keep your vehicle safe and level when you’re towing and hauling as it improves your ride quality.


There have been a few companies that have tried to imitate Timbren’s products. When a great idea turns up, everyone wants a piece of the action! And many have tried to improve on the original but with zero success.

Foam springs entered the market back in 2010. As a new product based on the Timbren SES model, it was a poor copy of the original. Instead of rubber compounds, they were made from gasinfused polyurethane (foam).

Timbren SES hollow rubber springs come in 5 different durometers (hardness of rubber) plus 25 different styles (size and shape). Foam products come in basically three shapes with 3 different densities.

So really, the main difference between SES rubber springs and foam is the material used in forming the spring. The original Timbren SES helper spring is made of cured natural rubber, whereas the more recent foam products involve gasinfused polyurethane.

Anyway, here’s the thing...

They are not recommended to be used in Northern states and Canada famously one of the industry leaders associated with foam even mentioned that "use SES springs in cold weather". In supercold weather, gasinfused polyurethane springs become brittle and break down. Timbren’s rubber springs, on the other hand, can handle extreme weather conditions.

Not only that, foam springs aren’t meant to handle heavyduty and severeservice applications. Timbren has over 400 SES kits that are engineered to custom fit virtually every vehicle that rolls off the assembly line, ready to assist every truck including heavyduty and severeservice applications.

Are SES rubber springs superior to foam? We think so. Here are 2 reasons:

Foam springs will get brittle and break down in cold weather
Foam springs are not able to handle heavyduty and severeservice applications

Timbren SES hollow rubber springs work fine in both hot and cold temperatures. Furthermore, they do extremely well when used for severeservice applications such as truck campers, snow removal, big fifth wheel trailers, and trucks with dump bodies.

Because of their unique characteristics progressive spring rate and selfdamping Timbren SES suspension upgrades are actually stronger than steel and more reliable than air.

Timbren’s DIY solution can be installed in your driveway in less than thirty minutes using tools you already have lying around the house. And the best part? It comes with a 100Day Moneyback Guarantee and a Lifetime Warranty. Head on over to Timbren.com and transform the way you tow and haul.
