{"product_id":"arb-differential-spreader","title":"ARB Differential Spreader","description":"\u003cp\u003eARBs 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.\n\u003cbr\u003eAir Locker Differential Case Spreader Tool;\u003c\/p\u003e","brand":"ARB","offers":[{"title":"Default Title","offer_id":45959954170108,"sku":"0770003","price":482.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/6518\/3740\/files\/c29623b23f9006527c172dfefface0cb.jpg?v=1717363014","url":"https:\/\/diycustoms.store\/products\/arb-differential-spreader","provider":"diycustoms.store","version":"1.0","type":"link"}
