This is the Fabtech Stealth front monotube shock, sold individually, engineered for the 2020+ GM 2500HD/3500HD with a 6in lift and 4WD.

About Fabtech
Fabtech Motorsports designs suspension lift systems and shocks for trucks and SUVs, with the Stealth line built as an affordable, all-black monotube shock option engineered with vehicle-specific valving for oversized tire packages.
FAQ
Is this shock sold individually or as a pair?
Individually. A complete front shock pair requires two units.
What is the piston diameter on this shock?
46mm, described by Fabtech as a high-flow piston design.
What finish does this shock have?
An all-black matte finish with a raised metal nameplate.
What separates the Stealth line from Fabtech's other shock lines?
Stealth was Fabtech's first all-black monotube shock, offering the monotube full-floating-piston design at a more affordable price point than Fabtech's Dirt Logic or Performance shock lines.
What lift height is this shock designed for?
A 6in lift system on 4WD 2020+ GM 2500HD/3500HD trucks.
What material is the piston rod made from?
A 14mm Nitrocarburized rod, which Fabtech states resists rock chips and corrosion better than a standard chromed rod.
Does this shock work with oversized tires?
Yes, the valving is specifically tuned for oversized tire packages typical of a lifted truck.
What keeps the ride consistent under hard use?
A full floating piston that separates the nitrogen gas charge from the oil, reducing shock fade.
Installation Instructions

- Position the new Fabtech Stealth shock and install the upper and lower mounting hardware.
- Torque all mounting hardware to the vehicle manufacturer's or Fabtech kit's specified torque values.
- Repeat on the opposite side to install a complete matched pair, then reinstall the wheels.
- Cycle the suspension through its full travel to confirm clearance before returning the vehicle to service.
