Designed to replace the factory plastic thermostat housing, this billet aluminum component delivers superior durability and enhanced thermal management for high-performance and heavy-duty applications.
Ideal for enthusiasts who demand reliable engine temperature regulation during spirited driving, towing, or track use, this thermostat housing ensures consistent coolant flow and helps prevent overheating. Whether you are pushing your vehicle on the track or navigating tough road conditions, the Granatelli billet housing provides a robust and long-lasting solution that maintains optimal engine efficiency.
Built with performance and reliability in mind, the Granatelli billet thermostat housing offers the following advantages:
This thermostat housing is crafted from premium billet aluminum, selected for its excellent thermal conductivity and superior strength-to-weight ratio compared to stock plastic housings. The CNC machining process ensures tight tolerances and a perfect fit, reducing the risk of leaks and enhancing durability.
The billet construction resists cracking, warping, and degradation caused by heat cycling and pressure fluctuations common in high-output engines. Additionally, the corrosion-resistant finish protects the housing from rust and chemical damage, extending its service life and maintaining reliable performance over time.
Designed to maintain full compatibility with OEM thermostats and sensors, this housing integrates effortlessly into the existing cooling system without requiring modifications.
Installation is straightforward and requires no special tools or modifications. The Granatelli billet thermostat housing is a direct replacement for the factory unit on the specified Jeep Grand Cherokee Trackhawk and Dodge Durango Hellcat models. Standard hand tools are sufficient to remove the old housing and install the new billet component.
For best results, it is recommended to replace the thermostat gasket or O-ring during installation to ensure a proper seal and prevent leaks. This upgrade is suitable for professional mechanics as well as experienced enthusiasts comfortable with basic engine maintenance.
This billet thermostat housing is perfect for Jeep Grand Cherokee Trackhawk and Dodge Durango Hellcat owners who require enhanced cooling system reliability and durability. It is especially suited for:
Granatelli Motor Sports develops performance parts for racers and enthusiasts, with a lineup that spans ignition components, exhaust cutouts, boost-control hardware, and billet accessories.

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!
