Product Description

The Rancho RS77401 RS7MT steering damper is engineered to reduce wheel shimmy, bump steer, and vibration on front-drive linkage systems of GM 4WD trucks and Jeep Wrangler JK models. Its monotube design with 46 mm bore and IFP delivers consistent damping even under towing loads or oversized wheel setups.

Featuring a hardened chrome piston rod, telescopic travel of 6.57 in, and integrated dirt-wiper protection, it's built for durability in off-road and daily driving conditions. Perfect for lifted vehicles when combined with the RS64100 mounting kit, this Rancho damper ensures responsive steering feel without requiring custom fabrication.
