This premium housing replaces the factory plastic unit, which is prone to cracking and leaking under the intense heat and pressure of high-performance driving. CNC-machined from billet aluminum and finished in a durable black powder coat, this housing offers both superior strength and a sleek, modern look.

Performance and Reliability Features:

  • Precision-engineered for a perfect fit on Trackhawk and Hellcat models.
