Tame wheel shimmy, bump steer, and vibration with the Rancho RS7MT Steering Damper (RS77405), a front steering stabilizer built for rigs running oversized wheels and tires.

  • Reduces shimmy & bump steer: Dampens wheel shimmy, bump steer, and vibration to help minimize on- or off-road driver fatigue.
  • Monotube gas design: Filled with all-weather fluid for cooler operation and control, rated to withstand internal temperatures of -40° to 248°F.
  • Strong and durable: 14mm hardened chrome piston rod resists scuffs and corrosion, with double-welded loops at stress areas, a double-strength closure, and a hot-form reserve tube.
  • Sealed against grit: An integrated dirt wiper sealing system helps keep moisture, dirt, and debris out of the shock.

A large 46mm fluon-banded piston delivers consistent sealing for precise control. Application-specific mounting installs without sleeves or extra hardware, and the black satin finish carries the distinctive Rancho red logo. Backed by Rancho's Limited Lifetime Warranty.
