Description

This Timbren SES kit is designed to enhance the suspension of your vehicle, particularly for towing and hauling. It replaces the jounce stop on the frame with hollow rubber springs that deliver a progressive spring rate. This means the springs work harder as the load increases, preventing rear-end sag, difficult handling, and corner sway. The system is designed to maintain a comfortable unloaded ride and requires no post-installation maintenance, unlike air bags. It also boasts an installation time of under 30 minutes.
