Timbren GMFK25S 1999-2010 GM 1500/2500/3500 HD Progressive Front Suspension Bump Stop System

The Timbren GMFK25S Suspension Kit is designed to enhance the front suspension of your LB7, LLY, LBZ or LMM. Timbrens are the go to suspension upgrade for commercial trucks and plow trucks that have additional weight added to the front of the chassis. Timbrens hollow rubber springs are engineered 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.

 Highlights:

• Easiest to use: Rubber cushions absorb road shocks and automatically adjust to uneven loads or road conditions. Easiest to maintain: There are no airlines or fittings to allow leaks. Simply bolt the kit on and you are set for a lifetime of trouble free suspension.
• Easiest to install: There are no holes to drill, no airlines to route and SES Kits can be installed in a matter of minutes using basic hand tools. The softer ride quality of todays trucks and the mediocre suspensions found on most trailers can cause excessive trailer sway, instability and suspension settling. Timbrens high performance suspension packages will ensure added safety and peace of mind.
