HQ (Handling Quality) Shocks have a monotube design that's been improved by Ridetech partnered with Fox Racing Shocks to replace OE shock absorbers as the basis for a performance suspension. Monotube shocks optimize performance using fewer components than twin tube shocks. The key advantage is that a larger piston & more efficient oil flow path create cooler operating temperatures & more consistent performance in extreme environments. These unique shock absorbers have been 16 years in the making, and the technology and overall upgrade they provide will change the ride and handling of your vehicle.
