Whether we’re towing with our Nissan Titan or our Toyota Tundra, our Timbren SES kit has been a game changer. Reduced all sag in the rear plus helps the tow rigs gain maximum control. Over a year with SES and we would never go back.


We purchased a 5th wheel lite camper to be pulled by our 2019 Ram 1500. First time I towed the camper I was afraid I had made a poor decision, yet my friends told me to check out air bags or Timbrens. I decided to go with Timbrens for the ease of install, and my son and I installed them in under an hour. What a difference these make!!! 110% different ride, tow and felt confident this time out! I am telling all my truck buds these are worth their weight in gold.


Countless miles of off-road trails and over 2 years of abuse, our Timbren Active Off-Road Bumpstops have not only been a huge advantage but also a necessary modification. Keeping our rig from bottoming out 1 trail at a time!


This is a first-class company with first-class products and first-class people. Thanks Timbren, proud to have your product under my vehicle.

Install right in your driveway, no special skills or tools needed. Be ready to ride and haul in less than 30 minutes. Then forget about ‘em — no post-installation maintenance required.


Our Aeon® springs feature a progressive spring rate. As load increases, our rubber springs push back even harder to level your load. Our springs also act like a shock absorber. This makes for a smooth, controlled ride loaded or unloaded.


From the beating heat of the Australian Outback to the sub-freezing winters of Canada, our Timbren SES kits are built to last in any conditions. They’re durable, too. In fact, our Aeon® rubber springs are even tougher than bullets.

Your questions, answered

You want all the info before choosing the right towing and hauling solution 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.
