Description
ARB’s Air Locker Differential Spreader is a professionalautomotive tool that no differential installer should be without. Most common Salisbury style axleassemblies (e.g., Dana Spicer model 44) require the use of a differential spreader in order to achieve therequired carrier bearing pre-load during set-up. Stretching the housing casting (or pumpkin’) open bysufficient enough force as to allow extra shim to be added to create the pre-load is the method that theOEM manufacture’s endorse, and most manufacture’s have included special spreader sockets’ in thehousing for exactly this purpose.
