Fabtech offers Dirt Logic 4.0 coilover shock absorbers in both a reservoir and non-reservoir style with an adjustable coilover construction. They even have a remote reservoir style that includes reservoir frame mounts for select applications that may not have room for a piggyback style shock. All Fabtech Dirt Logic 4.0 coilover shocks feature a 4"" stainless steel body with a 3.875"" billet aluminum piston and Fabtech's exclusive 1.25"" NitroSteel matte black piston rod. For the coil portion, Fabtech uses Eibach coil springs. The piston keeps the oil & nitrogen gas separated which prevents fading and maintains consistent ride quality. | Fabtech Dirt Logic 4.0 Coilover Shock FTS835002"
