100% All-Aluminum construction ensures the best performance and durability. The mounting tabs and brackets are much stronger and more durable than the OE plastic design. In addition, the Heat Exchanger also features an integrated bolt on rock guard to keep the cooler safe. This rock guard is metal and much more robust than the factory plastic rock guard. Now you can feel more confident that your cooling system is safer from debris.By combining the Heat Exchanger and Transmission Cooler into a full cooling module, CSF was able to run the same size core as the G8X Heat Exchanger. The Auto Transmission Cooler uses the same dual core design as the G8X Transmission Cooler which is fitted to the new Heat Exchanger. This creates a cooling module that comes as a single unit.
