Description
The CSF External Transmission Oil Cooler Kit is the essential upgrade for 2021–2025 Ford Bronco 2.7L V6 owners who demand more from their off-road adventures. While the Bronco Raptor comes factory-equipped with a robust transmission cooler, the standard 2.7L model is left vulnerable to heat-related performance issues—especially when loaded with gear, oversized tires, or during demanding trail use.
Built around CSF’s Micro-Channel Technology, this bolt-on cooling system replaces the factory’s limited water-to-oil cooler with a high-capacity, air-to-oil unit. The result: drastically lower transmission temperatures, improved performance, and increased reliability.
Whether you’re climbing rock faces, desert running, or overlanding through remote terrain, CSF delivers the transmission protection your Bronco should’ve had from the factory. Designed with motorsport-grade components and validated through real-world testing, this kit is the perfect combination of innovation and performance.
