Description

ARBs Air Locker differential case spreaders are professional automotive tools 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 setup. Stretching the housing casting (or pumpkin) open by sufficient enough force (allowing extra shim to be added to create the pre-load) is the method that the OEM manufactures endorse—and most manufacturers have included special spreader sockets in the housing for exactly this purpose. 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 ARBs 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.

Additional details:

* Allows the housing to be stretched in a safe and controllable way, which reduces the risk of causing permanent damage to the housing
* Comes in a durable carry case with a dedicated powdercoated parts tray for easy storage and transport
* Pre-drilled with a hole pattern that suits most of the commonly available axle types
* Suited to pre-loading shim adjusted banjo style axle assemblies
