Included Shocks

Increase the front suspension damping capacity on 2017 GM 2500 & 3500 HD’s with Fabtech’s Dual Shock system.  This system is designed to be installed exclusively with a Fabtech 6” RTS system for a total suspension upgrade.

This newly designed shock system utilizes 1/4” thick steel frame brackets for the upper mounting end of the shocks without having to cut the factory inner fenderwell for installation. The lower shock mounts are incorporated into the Fabtech 6” RTS system for a fast install.

The Dual Shock System is compatible with both Gas and Diesel model HD’s with 6” RTS systems and comes finished in black powder coat.

Dirt Logic 2.25 Stainless Steel Resi

Dirt Logic 2.25’s are designed to replace factory shocks with a larger, more robust configuration. The 2.25 size is what separates it from other replacement take apart shocks for a superior ride, both on and off road. Shocks are pretuned for each Fabtech suspension, accounting for larger tires, providing the finest all around damping.
