Buying Guide

Match inlet/outlet size

Confirm 5/16" or 1/2" hose compatibility with your vehicle or trailer line to avoid adapters and leaks

Choose pass count for cooling needs

6-pass and 8-pass tube-and-fin designs increase surface area and cooling for heavy towing or high transmission temps

Prefer aluminum construction

Aluminum coolers and housings resist corrosion and conduct heat well, improving long-term cooling and durability

Check sensor and gasket inclusion

Kits that include oil cooler sensors and gaskets simplify installation and reduce need for extra parts

Consider universal vs vehicle-specific

Universal tube-and-fin kits offer flexible mounting for many setups, while vehicle-specific housings provide bolt-on fit and integrated sensors
