Product Description

The Fabtech FTS21196 Dirt Logic 2.5 Stainless Steel Coilovers are a front shock upgrade designed to replace the factory spacer-style setup included with Fabtech's basic 6" suspension lift systems for 2007-2018 GM 1500 trucks and 2007-2014 GM 1500-series SUVs. Developed from Fabtech's desert racing experience, these coilovers deliver exceptional damping capacity for aggressive offroad driving while maintaining a comfortable highway ride. Each coilover is ride-tuned specifically by vehicle application rather than relying on generic valving, ensuring the best possible performance for the GM 1500 platform.

Built with all-new stainless steel and aluminum construction, these coilovers feature high-grade 304 stainless steel bodies that provide industry-leading corrosion resistance with a precision machine finish. The NitroSteel piston rod offers superior hardness and corrosion protection compared to traditional chrome rods, while the 2.25" billet aluminum piston ensures consistent damping even under extreme heat and stress. The threaded stainless steel body allows nearly infinite ride height and preload adjustment within the recommended lift range, giving owners the ability to fine-tune their stance and ride quality.

These coilovers are sold as a pair and are intended for use exclusively with compatible Fabtech 6" lift systems. They are a direct upgrade from the spacer kit and bolt into the existing mounting points using factory shock mounting hardware. Factory shock mounting bolts are reused during installation, and optional billet reservoir clamps (FTS89935) and shock boots are available separately. A one-year warranty on leakage applies, and service seal kits are offered for long-term maintenance.
