Billet Technology Supercharger Coolant Cap Jeep Grand Cherokee Trackhawk

Keep the Heat Out of Your Supercharger Circuit in Style

The Billet Technology 3001112 supercharger coolant cap replaces the factory plastic supercharger intercooler reservoir cap on your 2018-2021 Jeep Grand Cherokee Trackhawk with a precision-machined piece crafted from solid 6061-T6 certified domestic aircraft-grade aluminum. Billet Technology engineers every cap in Lake Worth, Florida with the same care as their signature catch cans and thermostat housings, so it fits and seals exactly like the factory cap while adding a premium appearance that matches the performance of your supercharged application.

Fitment

Note: This cap is engineered exclusively for the Jeep Grand Cherokee Trackhawk supercharger coolant reservoir. Not compatible with Dodge Hellcat, Demon, Durango Hellcat, or Ram TRX applications, which use separate Billet Technology part numbers.

Frequently Asked Questions

Does part number 3001112 fit the Dodge Hellcat or Demon?

No. The 3001112 is engineered specifically for the 2018-2021 Jeep Grand Cherokee Trackhawk. Hellcat, Demon, Durango Hellcat, and Ram TRX applications use separate Billet Technology part numbers sized for their own reservoir necks.

Does the supercharger coolant cap maintain OEM pressure rating?

The 3001112 is designed to match OEM thread engagement and sealing. It maintains the same sealing characteristics as the factory plastic cap.

Is the supercharger coolant system separate from the main engine cooling circuit?

Yes. On the Trackhawk, the supercharger has its own dedicated intercooler coolant circuit with a separate reservoir from the main engine cooling system.
