What Owners Say
Owners and enthusiasts recognize the Ford Racing FR differential covers as rebadged Spicer units, often noting you can save around $100 buying the Spicer version directly. The covers earn praise for increased fluid capacity and improved heat dispersion, both valuable upgrades over stock. Some experienced users have shifted back to stock covers after seeing comparative testing, suggesting the performance gains may be modest for street-driven trucks. The primary appeal remains the added protection from a thicker casting and convenient service features like integrated drain plugs. For those seeking extra insurance against trail damage or towing stress, these covers maintain a solid reputation in the F-150 and Raptor communities.
