Late Model Stacked Radiator & Oil Cooler Packages

Ford & Chevy Style Configurations

The PWR Late Model Stacked Package is our latest cooling solution engineered specifically for pavement Late Model racing and other high-demand applications. Designed using the same proven approach found in our NASCAR cooling programs, this system delivers maximum thermal efficiency, durability, and consistency under extreme race conditions.

This stacked package integrates a high-efficiency radiator with a 19mm oil cooler core mounted directly behind it, reducing oil temperatures while simultaneously improving overall coolant temperature stability. By pulling heat out of the oil system, thermal load across the engine is reduced—resulting in more consistent performance during long green-flag runs.

The Late Model Stacked Package is available in both Ford-style and Chevy-style configurations, allowing proper fitment across a wide range of chassis and engine combinations. Two height options are also offered to accommodate packaging needs. The taller configuration is equipped with a 16” SPAL high-performance fan, while the shorter version utilizes a 14” SPAL fan, both selected to provide exceptional airflow and cooling efficiency.

For extreme operating conditions and increased boiling points, this package is fully compatible with the PWR Pressurized Water Kit, making it ideal for the most demanding racing environments.
