Litens 920668K HellRaiser 3.17" Pulley Kit for Demon, Challenger, Charger, Durango SRT Hellcat, Trackhawk & TRX 6.2L HEMI

Since the Hellcat first hit the market, it's been debated as to how much safer a clutched pulley just like the OEM decoupling 3.35" would be on modified IHI Hellcat superchargers. Litens comes through with their high quality heavy duty 3.17 pulley upgrade. Using the OEM design developed specifically by Litens this pulley will reduce stress and associated wear on your supercharger's bearings and rotors.

Litens testing shows that this pulley makes approximately 45 HP on 93 and 65 HP on MS109 Race Gas for Demon/Redeye Superchargers at sea level. Litens testing shows no tuning is required with this pulley upgrade and stock harmonic damper.
