Description Part Numbers
 

Eaton Posi limited slip differentials feature chatter free carbon disc clutch packs and precision forged gears for maximum performance and durability. The tried-and-true clutch pack design works great for daily driving, rally racing, mild off-roading, drag racing, and circuit racing. Each unit is fully rebuildable and can be fine tuned by replacing the internal springs and clutches with stiffer or softer ones.

Selecting the right Eaton Posi model is easy using the detailed differential application table below. All of the currently available Eaton Posi Differential models are listed according to the vehicle(s) for which they are compatible. Simply find your vehicle in the list and locate the Eaton Posi part number in the far right column and select it from the pull-down menu above. In some instances you will need to know what type of axle your vehicle has and if you need help finding this information you can call or email us for assistance.
