FOX Adjustable Through Shaft (ATS) design
Offers unrivaled steering control
Integrated reservoir for additional fluid capacity & improved cooling
Direct fit for INEOS Grenadier – 2 bolt removal and installation process
FOX/AO Performance Series ATS Grenadier Steering Damper
The FOX Performance Series Adjustable Through Shaft (ATS) steering stabilizer for the INEOS Grenadier was designed as a direct fit Grenadier performance upgrade by Agile Offroad. This steering stabilizer offers unrivaled steering control and a striking high tech appearance. The technologically advanced design cancels unwanted steering forces in both directions, taking the place of two conventional opposing stabilizers. It will also respond to your input with 24 clicks of external adjustment to fine tune the feel.
The ATS represents a revolutionary breakthrough in stabilizer design. Since the ATS runs a shaft all the way through, it makes the surface area on both sides of the stabilizer’s piston equal. This unique two-in-one through-shaft design creates a pressure balance so no unwanted push is felt in either direction.
The integrated reservoir allows for additional fluid capacity and improves cooling during extreme use.
 
The installation on this one is about 5 minutes.  An 18mm socket and a 21mm socket.  Torque wrench capable of 100 ft/lbs is required.  Very easy job.  Can do on your driveway or garage floor.
