{"product_id":"arb-differential-spreader-1","title":"ARB Differential 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":44042474422426,"sku":"ARB0770003","price":430.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0492\/6121\/5898\/products\/5ac30e536f50395934687f49ef5b19ff_4c0de37c-d5cf-4f92-a0d1-ff41d355ddf7.jpg?v=1698497731","url":"https:\/\/prime-wheels-and-tires.myshopify.com\/products\/arb-differential-spreader-1","provider":"Prime Wheels and Tires","version":"1.0","type":"link"}
