Introducing the CSF Bronco 2.7L External Transmission Oil Cooler Kit. This complete bolt-on kit was designed to provide the kind of protection serious off-roaders need. Whether you’re scaling dunes, crawling rocks, or just exploring the backcountry, overheating your transmission can put a real damper on your adventure. CSF’s new system offers a major performance boost over the factory liquid-to-liquid cooler and improves upon the design of the factory Bronco Raptor system.
The OE Transmission Oil Cooler from Ford is a small, water-to-oil stack cooler. While adequate for daily driving, it can easily become overwhelmed when these rigs are pushed to their limits. It’s not just high-horsepower builds or hardcore off-roaders who need better cooling. Many overlanders, campers, and weekend adventurers add significant weight and drag to their Broncos. Roof-mounted tents, spare tires, fuel cans, and oversized tires all increase the load on both the engine and transmission. With CSF’s kit, your 2.7L Bronco gains the cooling capacity it should have had from the factory, providing crucial protection and preserving performance. The CSF system was built around a high-performance transmission oil cooler built with CSF’s Micro Channel Technology. The core features a super-high-pressure 26mm 12-channel microtube design that maximizes oil flow and surface area contact. Constructed of 11 rows of cooling tubes and paired with 12 rows of 8mm multi-louvered high-performance fins, it delivers outstanding heat transfer efficiency. A CNC billet-machined thermostatic plate replaces the factory stack cooler which reroutes transmission fluid to the new cooler mounted in front of the radiator. Motorsport-grade lines and patented quick-release fittings by DYME PSI ensure a clean, fast, and straight-forward installation.
CSF leveraged decades of cooling experience to design their first complete Oil Cooler Kit. As a leader in performance cooling technology, CSF wanted to bring the best possible kit to the market.
