2001-2010 LB7 / LLY / LBZ / LMM Duramax Timbren Suspension Enhancement System - Front Kit

Weight from a snowplow or heavy aftermarket accessories can cause dangerous front-end sag and sway. When heavy weight is distributed only onto the front two tires, it can create difficult handling conditions and risk damage to your front-end suspension from bottoming out.

Timbren SES front kits level out your front-end load, making for a safe, controlled ride.

How? Aeon® rubber springs deliver a progressive spring rate. As load increases, our rubber springs push back harder, eliminating squat, sway, and roll to put you back in control of your vehicle. After installation, the rubber spring should be in contact with the front axle.

What makes Timbren SES kits different from other suspension enhancement systems? Unlike air bags, these kits require zero post-installation maintenance. And unlike other systems, you can install and haul in under 30 minutes, right from your driveway.

Note: Even though you’re increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating). Please make sure that the load does not exceed the GVWR set by the manufacturer.
