Frequently Asked Questions
Will the Billet Technology 300205 affect supercharger boost pressure?
No. The 300205 is a cosmetic cover that snaps over the outside of the bypass valve housing. It does not contact or alter the bypass valve mechanism.
Does the 300205 fit the Durango and Trackhawk bypass valve, not just Hellcat cars?
Yes. This fits the same 6.2L supercharger bypass valve assembly used across Challenger and Charger SRT Hellcat, Challenger SRT Demon, Durango SRT Hellcat, and Jeep Grand Cherokee Trackhawk, as listed in the fitment table above.
What finish options are available?
The 300205 is available in satin / Raw Aluminum finish.
