Fidanza Performance is excited to offer the go to name in differentials - Eaton!

Eaton produces a range of differentials designed to improve traction, handling, and vehicle stability across various applications, from heavy-duty trucks to performance cars and off-road vehicles. One of their most popular products is the Truetrac Limited-Slip Differential, which uses helical gears for smooth, maintenance-free performance. The Detroit Locker is a fully locking differential, providing 100% power to both wheels when necessary, making it ideal for off-road or high-performance use. The Posi Limited-Slip Differential uses a clutch-based system for better traction under acceleration, commonly found in muscle cars. Eaton also offers the ELocker, an electronically controlled locking differential that allows drivers to engage or disengage the lock at the push of a button, which is useful for off-roading. Additionally, the Helical Limited-Slip Differential works similarly to the Truetrac, offering smooth and quiet operation while providing additional traction when needed. Overall, Eaton's differentials are known for their engineering, reliability, and performance, suited for various driving needs.
