Küryakyn offers complete Hypercharger kits for most H-d® models equipped with stock or popular aftermarket carburetors.

U.S. Patent # Des. 340,513

• Outstanding performance on stock or mildly modified engine up to 90 HP. With the addition of the Stinger Trap Door (P/N 8498, sold separately), we have tested and proven the Hypercharger to support engines up to at least 130 HP
• Stock or touring applications where added performance is desired, but not paramount
• Custom applications where matching or contrasting color trap door and butterflies are used as a styling accent

Do They Work?

Normally, replacing a stock air cleaner with a Hypercharger will net you a 7-9 horsepower increase at the rear wheel, with no other modifications! Add a carb recalibration kit, a good performance exhaust system (not drag pipes) and a 12-14 horsepower increase is normal.

NOTE: See FITMENT GUIDE for specific application, color availability and other important information.
