Differentials
Differentials distribute engine torque between drive wheels, allowing them to rotate at different speeds through corners while maintaining traction. Upgrading from a factory open differential to a limited-slip or locking differential is one of the most impactful drivetrain improvements you can make for towing, off-roading, drag racing, or any application where both wheels need to work together under load.Popular Differential UpgradesTop upgrades include Eaton Detroit Locker and Eaton Truetrac limited-slip units for GM, Ford, Dana, and Chrysler axles, ARB Air Lockers for Jeep and truck off-road applications, and OS Giken Super Lock LSD units for JDM performance platforms. Locker conversions for Dana 44 and Dana 60 front axles are essential for serious rock crawling, while Truetrac helical LSDs deliver traction improvements without aggressive locking behavior for street and tow applications.What is the difference between a locker and a limited-slip differential?A locking differential ...
