TBA Machine Billet Demon, Redeye & Hellcat Supercharger Coolant Reservoir Cap

The TBA Machine Billet Demon, Redeye & Hellcat Supercharger Coolant Reservoir Cap is a premium engine bay upgrade designed specifically for enthusiasts who appreciate both performance-inspired styling and high-quality craftsmanship. Precision CNC machined from billet aluminum, this coolant reservoir cap replaces the factory plastic cap with a significantly more durable and visually appealing component that complements the aggressive look of supercharged Gen 3 HEMI platforms. Whether you’re building a show-quality Hellcat, maintaining a weekend track car, or simply adding refined details to your engine bay, this cap offers an easy way to elevate the appearance of your vehicle while utilizing materials built to withstand the harsh underhood environment. Its billet construction provides increased resistance to heat, fading, cracking, and long-term wear commonly associated with factory plastic components.

Although often overlooked, engine bay details can make a significant impact on the overall presentation of a vehicle. The factory coolant reservoir cap performs its intended function, but many owners of Hellcats, Redeyes, Demons, Trackhawks, and TRXs prefer upgraded components that reflect the quality and attention to detail found throughout the rest of their build. The TBA Machine Billet Reservoir Cap delivers that finishing touch by offering a precision-machined replacement that installs in minutes and immediately enhances the appearance of the supercharger cooling system. For enthusiasts attending car shows, meets, or performance events, small upgrades such as this billet cap help create a cleaner and more cohesive engine compartment.

One of the biggest advantages of billet aluminum accessories is their ability to withstand years of exposure to elevated temperatures, moisture, and chemical contaminants without degrading. Unlike molded plastic caps that may become brittle or discolored over time, the TBA Machine cap is engineered for long-term durability while maintaining its premium appearance. Its precise machining ensures a secure fitment while retaining the functionality expected from an OE-style replacement. The cap is equally at home on a stock vehicle or a heavily modified build featuring pulley upgrades, larger throttle bodies, ported superchargers, aftermarket coolant tanks, or high-horsepower tuning packages.

For enthusiasts who take pride in every aspect of their vehicle, investing in premium engine bay accessories can help distinguish a build from the crowd. The billet coolant reservoir cap serves as a subtle but effective upgrade that combines aesthetics, durability, and craftsmanship into a simple bolt-on modification. Whether you’re refreshing an aging engine compartment, preparing for a car show, or completing a full engine bay makeover, this component offers a practical and attractive solution.
