Timbren 2017 - 2023 Ford F250 & F350 SuperDuty SES Severe Rear Kit # FRTT350J

Timbren 2017 - 2023 Ford F250 & F350 SuperDuty SES Severe Rear Kit # FRTT350J. Both the Severe and Classic products feature the progressive spring rate of Aeon rubber springs. As load increases, Timbren rubber springs push back harder, eliminating squat, sway, and roll. But the 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.

What makes Timbren SES kits different from other suspension enhancement systems? Unlike air bags, Timbren 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. This kit includes 2 Patented Aeon SES suspensions (hollow rubber springs), 2 spacers, 2 steel mounting brackets and all necessary installation hardware.
