This set boasts an 8.00-inch ring gear diameter, a 25-spline pinion for secure engagement, and utilizes 10 ring gear bolts to ensure durability and reliability. The 3.80 gear ratio is optimized to deliver improved acceleration and more effective torque delivery, making it suitable for both daily driving and performance-oriented applications.

This commitment to excellence is further reinforced by a 1-year warranty against manufacturer defects, offering peace of mind to the end-user. The ZG F8-380 is compatible with a wide array of Ford and Mercury vehicles spanning several decades. This includes models such as the Ford Fairlane (1962-1967), Ford Mustang (1964-1973), Ford Pinto (1971-1980), Mercury Comet (1962-1977), and many others listed. Potential buyers are encouraged to verify specific fitment for their vehicle, as the product listing offers a comprehensive search tool to confirm compatibility.
