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 our Timbren SES severe service kits.
So what’s the difference between our severe service kits and classic Timbren SES kits?
Both products feature the progressive spring rate of our Aeon® rubbers springs. As load increases, our rubber springs push back harder, eliminating squat, sway, and roll.
But our 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, our 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.

Note: Even though you’re increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating). Please make sure that the load does not exceed the GVWR set by the manufacturer.
