{"product_id":"arb-differential-spreader","title":"ARB Differential Spreader","description":"ARBs Air Locker(TM) 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(TM) Differential. As a part of ARBs Air Locker(TM) Tools range of differential service\/installation equipment, this specialty tool offers an easy, quick and highly effective way of pre-loading these axles.","brand":"ARB","offers":[{"title":"Default Title","offer_id":49117586129148,"sku":"ARB0770003","price":469.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0077\/1791\/2658\/files\/6bfd4be073c79755cb8074d25fcd5c77.jpg?v=1779147484","url":"https:\/\/www.outlawraceengines.com\/products\/arb-differential-spreader","provider":"Outlaw Race Engines","version":"1.0","type":"link"}
