The Granatelli Motor Sports Billet Thermostat Housing is a precision-engineered upgrade tailored for the high-performance 6.2L engines in the 2011–2021 Jeep Grand Cherokee Trackhawk and the 2011–2026 Dodge Durango Hellcat. Designed to replace the factory thermostat housing, this billet aluminum component enhances coolant flow and reduces stress on the thermostat spring, ensuring reliable temperature management under demanding driving conditions.
Ideal for enthusiasts who push their vehicles hard on the street or track, this thermostat housing improves cooling system efficiency, helping maintain consistent engine temperatures critical for performance and engine longevity. Its sleek black anodized finish not only offers corrosion resistance but also adds a professional, OEM-style appearance to the engine bay.
Engineered for both durability and improved cooling performance, the Granatelli Billet Thermostat Housing offers the following advantages:
This thermostat housing is precision-machined from 6061-T6 billet aluminum, a material prized for its excellent strength-to-weight ratio and thermal conductivity. This ensures durability in high-temperature engine environments while efficiently dissipating heat to support optimal cooling system performance.
The black anodized coating enhances corrosion resistance and adds a refined look that complements the engine bay. The design eliminates the restrictive flow bridge found in the factory housing, allowing coolant to circulate more freely and reducing pressure on the thermostat spring. Flush mount bolts further reduce turbulence, extending thermostat life and improving overall reliability.
The integrated 1/2" pipe thread port adds versatility for monitoring engine temperatures or installing additional cooling system accessories, making this housing a practical upgrade for performance enthusiasts.
Installation is straightforward and requires only basic hand tools, making it accessible for both professional mechanics and experienced enthusiasts. This billet thermostat housing is a direct fit replacement for the factory thermostat housing on 2011–2021 Jeep Grand Cherokee Trackhawk and 2011–2026 Dodge Durango Hellcat models, requiring no modifications.
It uses the factory bolts on the exterior to maintain the original equipment appearance and function, ensuring a clean and professional installation. The no-gasket design simplifies the installation process, reducing the risk of leaks and saving time during maintenance or upgrades.
This billet thermostat housing is perfect for Jeep Grand Cherokee Trackhawk and Dodge Durango Hellcat owners who demand enhanced cooling system performance and durability. It is especially suited for enthusiasts who regularly drive their vehicles in high-performance or track environments and want to ensure reliable engine temperature control. Additionally, it appeals to those seeking a high-quality, OEM-style upgrade that improves coolant flow without compromising appearance or fitment.

ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
