Maximize Efficiency with ATI Underdrive Dampers

Unlock hidden horsepower in your 2011+ Dodge 5.7L or 6.4L VVT Hemi with the ATI 5.67-inch Underdrive (UD) Super Damper. By reducing the accessory drive speed by 15%, this damper minimizes parasitic drag, allowing your engine to rev more freely and efficiently. This is an essential upgrade for enthusiasts looking to optimize their engine's power output while maintaining superior harmonic vibration control.

Why Choose ATI Underdrive?

• 15% Underdrive: Reduces parasitic loss from accessories for improved throttle response and power.
• Precision Balance: Eliminates destructive torsional vibrations that can lead to engine damage.
• Lightweight Aluminum: High-strength material reduces inertia for quicker acceleration.
• 6-Groove Configuration: Designed for perfect belt alignment and secure operation.
• VVT Compatible: Fully tested to work seamlessly with modern Hemi VVT systems.

The ATI Super Damper is not just a pulley; it is a critical engine component designed to protect your crankshaft and bearings from the harmful effects of harmonic resonance. Unlike stock dampers that can fail under high-stress conditions, the ATI unit is built to last, providing consistent performance in both daily driving and competitive environments.
