Performance Series 2.0 IFP steering stabilizers take the load off your Wrangler JK's steering components -- PN 985-24-145 keeps your tires tracking straight and true--especially if you are running oversized off-road tires which have a tendency to seek out traction in any direction. The design uses the same advanced damping technology found in FOX Performance Series shocks including IFP technology, an impact-extruded 6061-T6 aluminum body, a heavy duty 1/2 heat-treated shaft, high performance piston and advanced seal technology.
