Fabtech manufactures a complete line of Dirt Logic shocks. One of the most popular is the nitrogen-charged 2.25 remote-reservoir for lifted vehicles. As its name implies, it has a 2.25-inch O.D. tube and reservoir and they're electroless nickel-plated to resist corrosion. The 2.25 also features a 7/8-inch piston rod, a floating piston, an O-ringed and recessed tank valve, a high-temperature Viton O-ring back-up rod seal, and anodized billet end caps. The 2.25 has a take-apart design for custom tuning, though each is prevalved for specific vehicle applications including front or rear shock positions. Custom lengths are available. Billet clamps are also available from Fabtech to mount the reservoir to the shock body.
