{"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.\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/1d00d44d52bfb60ac30b3c87022df2ab.PDF\"\u003eWarranty\u003c\/a\u003e\u003cbr\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/8e5ac58d82b8eeb95061f06067313a30.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003cbr\u003e","brand":"ARB","offers":[{"title":"Default Title","offer_id":45441473642780,"sku":"ARB0770003","price":469.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0557\/7614\/9689\/products\/5ac30e536f50395934687f49ef5b19ff.jpg?v=1686793643","url":"https:\/\/www.demonicperformance.com\/products\/arb-differential-spreader","provider":"Demonic Performance ","version":"1.0","type":"link"}
