With conventional steering stabilizers, turning in one direction creates an increase in pressure inside the stabilizer as the Shaft occupies more volume in the Body and displaces the oil. The repercussion is a push or pull steering force felt by the driver as the stabilizer attempts to return to its neutral state. To overcome this unidirectional force, dual opposing stabilizers are often used, but this requires additional mounting hardware and space. 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. The Performance Series 2.0 Stabilizer TS includes application specific mounting hardware and is available in multiple clamp sizes for stock or aftermarket heavy duty tie-rods.
