Quadratec Part No: 16104.9103 Manufacturer Part No: 0770003
ARB’s Air Locker Differential Spreader is a professional
automotive tool that no differential installer should be without. Most common Salisbury style axle
assemblies (e.g., Dana Spicer model 44) require the use of a differential spreader in order to achieve the
required carrier bearing pre-load during set-up. Stretching the housing casting (or ‘pumpkin’) open by
sufficient enough force as to allow extra shim to be added to create the pre-load is the method that the
OEM manufacture’s endorse, and most manufacture’s have included special ‘spreader sockets’ in the
housing for exactly this purpose.

Product Details
Insufficient pre-load can result in bearing failure, or ring and pinion failure on any differential, and
possible oil/air leakage issues in an Air Locker Differential. As a part of ARB’s Air Locker Tools range of differential service/installation equipment, this specialty tool offers an easy, quick and highly effective way of pre-loading these axles.
Features:
Designed by ARB to quickly and easily install onto most shim adjusted automotive differentials.
Allows the housing to be stretched in a safe and controllable way which reduces the risk of causing permanent damage to the housing (i.e., from overspreading the housing).
Pre-drilled with a hole pattern that suits most of the commonly available axle types.
Also suited to pre-loading shim adjusted Banjo style axle assemblies (e.g., Isuzu 26 spline).
Comes in a durable carry case with a dedicated powder coated parts tray for easy storage and transport.
Economically priced at roughly the labor & materials cost of having to re-preload one axle (i.e., a differential that was set-up without a spreader that is now showing symptoms of under pre-loading).
