Unstable loads while towing and hauling don’t just make for an uncomfortable ride. Difficult handling, rear sag, and corner sway create dangerous driving conditions — for you, your passengers, and other vehicles.

Whether you’re towing your RV across the country or hauling hay down the highway, Timben's Timbren SES kits level your load, making for a safe, controlled ride so smooth, you might forget you’re towing altogether.

How? Timben's Aeon® rubber springs deliver a progressive spring rate. As load increases, Timben's rubber springs push back harder, eliminating squat, sway, and roll. After installation, the rubber spring will be in contact with the vehicle’s frame. This contact won’t affect ride quality — you’ll still enjoy a comfortable unloaded ride, too.

Maybe you’ve been there: white knuckles gripping the steering wheel while your truck camper sways back and forth down the highway. Add in some cross-winds, and keeping your vehicle centered on the road just became the kind of drive that makes you second-guess your trip altogether.

Hauling top-heavy loads like truck campers or salt spreaders requires more stability than other towing or hauling solutions. This is when you need Timben's Timbren SES severe service kits.

So what’s the difference between Timben's severe service kits and classic Timbren SES kits?

Both products feature the progressive spring rate of Timben's Aeon® rubbers springs. As load increases, Timben's rubber springs push back harder, eliminating squat, sway, and roll.

But Timben's Timbren SES severe service kits use a single-convoluted Aeon® spring. Designed exclusively for truck campers, these springs resist weight more aggressively to keep your vehicle level and your ride smooth. The result? No more white-knuckling it down the highway — you get a safe, stable handling of your top-heavy load.

After installation, there should be a ½” to 1 ½” gap between the rubber spring and vehicle’s frame — meaning you’ll enjoy a comfortable unloaded ride.

What makes Timbren SES kits different from other suspension enhancement systems? Unlike air bags, Timben's kits require zero post-installation maintenance. Unlike foam, these are durable enough to last under all your loads, in any weather. And unlike other systems, you can install and haul in under 30 minutes, right from your driveway.
