Stealth Shocks


Stealth is the first all black monotube shock absorber, with an identifiable raised metal nameplate, that represents the signature of quality you can rely on for a superior ride at an affordable price.

Stealth monotube shocks are built with a 46mm diameter high flow piston and vehicle specific valving, for a great ride with oversized tires.

All Stealth shock absorbers feature Nitrocarburized piston rods that are superior to chromed rods in durability and corrosion resistance. These “Nitrocarb” piston rods are finished in matte black for a complete “black out” shock package.


  • - 50mm OD seamless steel body
  • - 46mm High flow piston for best ride
  • - Vehicle specific valving designed for oversized tires
  • - Full floating piston separates gas from oil for a consistent ride
  • - 14mm Nitrocarb piston rod resists rock chips and rusting
