Ripatuned Incognito Lower Damper Sleeve Kit With Crank Pin

Unlock up to 775 WHP without removing your factory crank damper.

The Ripatuned Incognito Lower Crank Pulley Sleeve Kit is one of the easiest and most effective ways to increase boost on your supercharged Gen 3 HEMI. Unlike traditional lower pulley upgrades, this patent-pending design installs directly over your factory harmonic damper, eliminating the need to remove the OEM damper or perform major modifications.

The result? More boost, more horsepower, and significantly less installation time.

Why Choose the Incognito System?

• Bolt-on installation with no factory damper removal
• No cutting, machining, or permanent modifications
• Can be installed by most DIY mechanics in about 2 hours
• Precision-machined billet aluminum construction
• Uses the factory crank bolt and OEM mounting locations for perfect alignment
• Maintains OEM-quality fitment with virtually no additional runout
• Compatible with the factory upper pulley or aftermarket upper pulleys

Real-World Performance

Extensive real-world testing has shown impressive gains on otherwise stock Hellcats.

Results on a stock 2019 Hellcat:

• Baseline: 659 WHP
• After installation: 749 WHP
• With supporting modifications: Up to 775 WHP

Testing also showed an increase of approximately 1.5-2 PSI of boost while remaining safe on a stock calibration under favorable conditions when using premium fuel.

No Tune Required*

One of the biggest advantages of the Incognito system is that it does not require an ECU tune for standard applications. Because the factory upper pulley remains unchanged, many owners choose this kit as a way to gain additional performance while minimizing the modifications typically associated with lower pulley upgrades.

For Redeye and Demon applications, 93-octane fuel is strongly recommended, especially at lower elevations. If only 91-octane fuel is available, a quality octane booster such as Boostane or Torco should be used.
