2003-2024+ Powerstroke/Cummins Synergy Tuned FOX ATS 2.0 Steering Stabilizer (6403-XX)

The Synergy tuned FOX ATS stabilizers combine the Through Shaft architecture with external adjustment, so you can dial the damping to your truck, your tire size and your driving. Like the TS, the through shaft design eliminates fluid displacement across the full stroke, removing the push or pull of a conventional stabilizer and delivering neutral, consistent control from a single unit.

• 6403-03 1-1/2" Clamp

• Through Shaft design eliminates shaft fluid displacement, delivering neutral damping in both directions.
• Removes the need for dual opposing stabilizers and the extra mounting hardware they require.
• Shares the load when running oversized tires, keeping the tires tracking true and preventing premature steering wear.
• Synergy specific valving tuned for heavy duty truck weight and steering geometry.
• External adjuster allows damping to be tuned without removing the stabilizer.
