ARB Air Locker Differential Case Spreader - 0770003

ARBs 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 manufactures endorse and most manufacture's 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.

Allows the housing to be stretched in a safe and controllable way which reduces the risk of causing permanent damage to the housing
Development - To ensure we meet your expectations ARB invests heavily in research and development. Our design and engineering team utilizes the latest CAD CAM parametric modeling systems and finite element analysis packages and is supported by subcontract companies and universities for special projects like vibration strength and crash testing. With an air bag equipped vehicle for example it is essential that the vehicle s crush rate and air bag triggering is not altered when a bull bar is installed. Our exhaustive testing programs ensure ARB bull bars meet these requirements. We also devote considerable time and resources toward to sourcing new products from around the world. IPF lights from Japan Warn winches from the US we scan the globe in search of equipment that meets both the demands of our customers and our own stringent quality requirements.
