Derived from the FOX's original ATS stabilizer, the Performance Series 2. 0 Stabilizer TS utilizes a Through Shaft (TS) architecture that eliminates shaft fluid displacement throughout the stabilizer's entire travel in both directions. By eliminating fluid displacement, the TS design delivers neutral and consistent damping of unwanted steering feedback. The result is unrivaled steering control at an unbelievable price point in a single, bolt-on stabilizer.
