GMF55AWD – Front Axle SES Suspension Upgrade

GMF55AWD - Front Axle SES Suspension Upgrade

This SES Suspension Upgrade fits the front suspension of a Chevrolet 4500, 5500, 6500 & 7500 Kodiak truck (see below for full list of applications). Each laser cut piece of steel is powder-coated to ensure a quality fit. We’ve engineered our hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs the harder they work to prevent front-end sag.



Product Features

  • Eliminate Vehicle Squatting & Sagging
  • Cushion Road Shocks
  • Improve Handling
  • Satisfaction Guarantee
  • Lifetime Warranty

Customer Reviews

"The Timbren system is the answer for rear end sag and soft handling! My 35ft 5th wheel handles much better, and I recommend Timbren without reservation."

- Larry V. - SD

“Timbren's work amazing! Absolutely as good or even better than air bags! Did it myself and only had time to drink 2 beer doing it! Easy install. Thanks for the advice. Simple yet very effective.”
