Part# 920669K

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 2.85 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.

Kit Includes:
1 - 2.85" Litens Supercharger Pulley
1 - End Cap (dust/tamper shield)
1 - 17mm Install Tool
1 - HD Belt

This pulley makes approximately 15 PSI on Hellcat and Trackhawk Superchargers and 18-19 PSI on Demon and RedEye Superchargers at sea level. This pulley kit does require use of larger fuel injectors and custom engine tuning.


Litens highly recommends against the use of additional idlers or heavy duty tensionsers and HD Belts with their pulley due to the higher risk of internal failure. Failure caused by running these other parts may not be covered under warranty.

Warranty: 1 Year manufacturer parts warranty against materials and manufacturing defects from date of purchase.
