Hellcat Supercharger to LS3 Head Adapter Kit
Bolt a Hellcat Blower onto Your LS3 Rectangle Port Heads
This adapter kit allows you to mount a Hellcat supercharger onto an LS engine with LS3/rectangle port heads, opening up aggressive forced-induction possibilities with Mopar’s proven blower tech. Designed to work with a 2-belt LSA accessory drive system, this kit includes a billet conversion hub and 3" 8-rib pulley that mates the Hellcat supercharger to a standard LSA-style 8-rib belt setup. No cutting or fabrication required—just a clean, complete install solution.
Adapts a Hellcat supercharger to LS3 rectangle port cylinder heads
Converts Hellcat pulley to 8-rib LSA spacing with billet hub and 3" supercharger pulley
Works with dual belt LSA accessory drives for independent blower and accessory function
Includes LS 4-bolt throttle body adapter and Hellcat MAP sensor port adapter
Made in Wichita, Kansas from aerospace-grade, USA-produced billet aluminum
Compatibility: This kit is designed to be used with an LSA crank balancer (ICT # BAL301) and LS3 corvette or LSA water pump (ICT # WAT101). For 8-rib supercharger belt tensioning and routing, we recommend billet tensioner and idler bracket kit (ICT # 551189-LS01). For all other accessories, we recommend them to be in Corvette -1 spacing. ICT Billet Corvette alternator and power steering bracket (ICT # 551521X-1) kit has proven to work in many chassis and a great choice to pair with this supercharger adapter kit.
