Crank Damper Sleeve Kit

The Ripatuned Incognito crank damper sleeve system is designed to provide real-world horsepower and torque gains by increasing boost levels between 1.5 and 2 psi. Constructed from billet aluminum, the sleeve fits precisely over the stock engine damper, utilizing the center crank bolt and stock pulley holes for alignment with no additional run-out compared to the OEM component. This system allows for a straightforward installation that can be completed by a DIY mechanic in under two hours. While an optional crank pin kit is included, use of it is at the owner's discretion. Users should note that modifying vehicles by pinning the crank or changing the upper supercharger pulley may be grounds for warranty voiding by the manufacturer. To ensure proper fitment and performance, customers must include their vehicle's specific year, make, and model in their order notes, as accessory belt drive lengths vary across applications. For Redeye and Demon models, 93 octane fuel is recommended at sea level due to higher boost levels, while 91 octane is only acceptable when used with fuel additives such as Torco or Boostane. Each kit includes the black satin sleeve, supercharger drive belt, supercharger accessory belt, a new OEM crank bolt, and detailed instructions.
