Hellcat Supercharger for Sale: What to Look For, What FAS Offers, and How to Get More Power Before You Buy
Hellcat Supercharger for Sale: What to Know Before You Buy
The Hellcat 2.4L IHI twin-screw supercharger is one of the most sought-after used forced induction units on the market. It shows up in Hellcat Chargers, Challengers, Ram TRX trucks, and Jeep Trackhawks — meaning wrecked examples hit salvage auctions constantly, and the price on used cores has stayed reasonable despite demand.
But not all used Hellcat blowers are equal. Before you hand over $2,000–4,000 for a core off eBay or a Facebook listing, here’s what to check — and why a rebuilt and ported unit from FAS Motorsports is a different product entirely.
What to Look For When Buying a Used Hellcat Supercharger
Check rotor condition. The Hellcat supercharger’s twin-screw rotors run on precision bearings with tight clearances. Worn bearings cause rotor wobble, which chews up rotor coating and eventually contacts the housing. Ask for photos of the rotor inlet with the inlet hose removed — look for scoring or witness marks on the rotor tips.
Ask about supercharger bearing history. OEM Hellcat blower bearings are rated for a service life that most stock vehicles never approach — but hard use, heat soak cycles, and detonation events accelerate wear. A unit pulled from a high-mileage drag car is not the same as one from a low-mile daily driver.
Confirm 2.4L vs 2.7L. (See our Hellcat supercharger size guide for full details.) The two units look similar; confirm the part number against the application before buying.
