SES Kits

Timbren SES (Suspension Enhancement Systems) Kits control trailer sway, eliminate suspension sag, control body roll, and improve vehicle ride. By replacing the factory bump stops with the SES kit you will increase your vehicles suspension performance when loaded down with heavy loads. Custom fit kits mean most applications bolt on using factory holes in a matter of minutes.

  • Helps to support heavy loads
