timbren ses vs air bags

The Set it & Forget It Helper Spring.

Some folks prefer to tinker with inflating and deflating air bags whenever they tow or haul, and that's totally fine. But if you're looking for something simpler, something that you can set and forget, and focus on your journey or the task at hand, then Timbren SES is for you.

Timbren SES kits come with a special spring system that adapts to the weight you add, making sure your vehicle stays safe and level. No more messing around with filling up air bags – that sounds pretty easy, right?

Want an Easy Install? We got you Covered.

Timbren SES kits are a simple DIY driveway install. No expensive tools required and no mechanic necessary. Go from install to haul in less than 30 mins with basic hand tools you already have laying around the house.

Put them on my 2019 F-150. Absolutely love them! Work awesome and 1/3 of the price of air bags.

Your questions, answered

You want all the info before choosing the right trailer suspension for you. And we want to help.

Nope. Unlike air bags, there’s no need to run air lines, check pressure, or watch for leaks. Our SES kits are a true set it and forget it solution.

Our Timbren SES kits are a helper spring for hauling and towing. Are they durable enough to go off-road? Absolutely. But if you are looking for a product built exclusively for absorbing harsh slams on the trail, our Active Off-Road Bumpstops are for you.

Our SES kits are designed to work on vehicles with factory ride height. But that’s where our Timbren SES Spacer Kits step in to fill the gap. With our spacer kits, your lifted vehicle can still benefit from the smooth, level ride that our SES kits offer.

No. Unlike Add-a-Leaf solutions, your unloaded vehicle’s ride height will remain unaffected by the installation of an SES kit.

Top-heavy loads that require maximum stability, like truck campers or salt spreaders, require the severe service kit upgrade. All other hauling and towing situations are covered by our classic Timbren SES kits.

A hassle-free Lifetime Warranty

All of our Timbren SES kits come backed by a Lifetime Warranty. On top of that we also include a 100-Day Money Back Guarantee. If at any point you have questions about your product simply give us a ring or shoot a message our way. We've got your back every step of the way.
