GMFW4C - Front Axle SES Suspension Upgrade
This SES Suspension Upgrade fits the front suspension of a GM medium & heavy duty trucks (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 (weight from a snowplow or heavy aftermarket accessories – such as a steel bumper) the harder they work to prevent front-end sag.
- Eliminate Vehicle Squatting & Sagging
- Cushion Road Shocks
- Improve Handling
- Satisfaction Guarantee
- Lifetime Warranty
"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."

“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.”
