  • Timbren SES are meant to improve ride while carrying a load, not to increase capacity - NEVER exceed Mfg. Gross Vehicle Weight Rating


A long time ago, in a decade a couple of decades ago, trucks were trucks and did truck things like drive similar to a tank and carry big things. Well, somewhere, thankfully, we decided that truck ride-quality should get to the level where our favorite vehicle could become our daily driver. As the truck evolved, it sacrificed ride quality while carrying a load for ride quality while empty. There's no reason to sacrifice anything; you can have the best of both worlds with Timbren Suspension Enhancement Systems.

What's the Timbren SES going to do for your truck, SUV, or van? Great question, and I'm glad you asked. Factory bump stops work okay when your vehicle is driving unloaded, but issues are going to arise when you test out your truck's payload capacity. When you're driving with a trailer, a fully loaded bed, or with a van full of gear, you're going to experience a lot of bounce and bottoming out. Timbren SES is going to offer more resistance and less travel while loaded to create a more stable and comfortable ride.

Timbren SES not only helps to increase load handling, these bad boys will also reduce sag and sway while towing, cushion your shocks, and help to keep your truck or SUV level. Since the Suspension Enhancement System works independently, you'll see improvement when carrying uneven loads, and improved roll stability.

Who needs Timbren Suspension Enhancment Systems? Anyone who tows frequently, hauls with a loaded truck or van, runs a snowplow, or anything else that pushes your vehicle to its limits. For the people who really push their trucks to the limit, Timbren also has the Severe Suspension Enhancement System available. This is recommended for applications such as slide-in campers & salt spreaders, not towing a boat or hauling firewood. The difference between the two is that the Severe SES delivers greater weight resistance than the SES, but in doing so, also sacrifices ride quality compared the regular SES.

Not convinced yet that Timbren Suspension Enhancement System is the exact thing you need to improve your truck driving life? Well, did I mention that they are also easy to install, maintenance free, and are backed by a lifetime warranty? Seriously? Did I mention those things? If not…Timbren SES are backed by a lifetime warranty, are a breeze to install, and are maintenance free. Get yours today!

Just had these installed on my 2012 Tundra. Wished I had them put on my 2010. The change in the ride while pulling my 26ft travel trailer is amazing. More stable feeling in the steering and much less bounce or rocking. Money well spent!
