{"product_id":"arb-air-locker-differential-case-spreader-nbf1rt","title":"ARB Air Locker Differential Case Spreader","description":"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.","brand":"ARB","offers":[{"title":"Default Title","offer_id":48324819583182,"sku":"ARB770003","price":140.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0731\/9391\/4574\/files\/agzyj7c8dqlz_6e906c12-2759-4052-be69-6ba56e920d95.jpg?v=1788658759","url":"https:\/\/shocksruplus.com\/products\/arb-air-locker-differential-case-spreader-nbf1rt","provider":"Shocksur Plus","version":"1.0","type":"link"}
