The OEMs endorse the method and most housings even have spreader sockets cast in for it. What they do not supply is the tool.\u003c\/p\u003e\n\u003cp\u003eThis is ARB's version: a pre-drilled plate with a hole pattern covering most commonly available axle types, two threaded rods and four blocks, which together stretch the housing in a controlled, even way rather than the improvised force that cracks castings. Get the pre-load wrong and you are looking at bearing failure or ring and pinion failure on any differential, and on an Air Locker you add oil and air leaks to the list.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePre-drilled differential spreader plate\u003c\/li\u003e\n\u003cli\u003eTwo threaded spreader rods with nuts\u003c\/li\u003e\n\u003cli\u003eFour spreader blocks\u003c\/li\u003e\n\u003cli\u003eDurable carry case with a powder coated parts tray\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eControlled, Even Spread\u003c\/strong\u003e\u003cbr\u003eStretches the housing in a safe and controllable way, which is the difference between reaching pre-load and permanently damaging a casting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFits Most Axles Out Of The Box\u003c\/strong\u003e\u003cbr\u003eThe plate is pre-drilled with a hole pattern that suits most of the commonly available axle types, so it is not a one axle tool.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBuilt For Shim Adjusted Banjo Axles\u003c\/strong\u003e\u003cbr\u003eSuited to pre-loading shim adjusted Banjo style axle assemblies, which is where the spreader is genuinely required rather than optional.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Method The OEMs Endorse\u003c\/strong\u003e\u003cbr\u003eSpreading the housing to add pre-load shim is the manufacturer endorsed method, and most housings include spreader sockets cast in for exactly this.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStays A Set\u003c\/strong\u003e\u003cbr\u003eSupplied in a durable carry case with a dedicated powder coated parts tray, so the rods and blocks stay with the plate.\u003c\/p\u003e\n\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x:auto;margin:8px 0 4px;border:1px solid #e6e6e6;border-radius:8px;\"\u003e\u003ctable style=\"display:table;width:100%;margin:0;border-collapse:separate;border-spacing:0;border:none;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"background:#ba232a;color:#ffffff;text-align:left;padding:12px 14px;font-weight:700;border:none;\"\u003eApplication\u003c\/th\u003e\n\u003cth style=\"background:#ba232a;color:#ffffff;text-align:left;padding:12px 14px;font-weight:700;border:none;\"\u003eFit\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#ffffff;font-weight:600;\"\u003eSalisbury style axles such as the Dana 44\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#ffffff;\"\u003e\n\u003cspan style=\"color:#1a7f37;font-weight:700;\"\u003e✓\u003c\/span\u003e Fits\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#f7f7f7;font-weight:600;\"\u003eShim adjusted Banjo style axle assemblies\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#f7f7f7;\"\u003e\n\u003cspan style=\"color:#1a7f37;font-weight:700;\"\u003e✓\u003c\/span\u003e Fits, this is the intended application\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#ffffff;font-weight:600;\"\u003eAdjuster nut type differentials\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#ffffff;\"\u003e\n\u003cspan style=\"color:#ba232a;font-weight:700;\"\u003e✗\u003c\/span\u003e Not applicable, use the adjuster nut pliers 0770002 instead\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#f7f7f7;font-weight:600;\"\u003eARB Air Locker installations in the above axles\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#f7f7f7;\"\u003e\n\u003cspan style=\"color:#1a7f37;font-weight:700;\"\u003e✓\u003c\/span\u003e Fits\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#ffffff;font-weight:600;\"\u003eVehicle\u003c\/td\u003e\n\u003ctd style=\"padding:12px 14px;border:none;border-bottom:1px solid #ececec;background:#ffffff;\"\u003e\n\u003cspan style=\"color:#b25e00;font-weight:700;\"\u003e●\u003c\/span\u003e Universal.

Its engineering campus in Kilsyth, Victoria still designs and builds the products the brand is known for, and ARB now runs offices in the USA, Europe and the Middle East with an export network reaching more than 100 countries.\u003c\/p\u003e\n\u003cp\u003eThe Air Locker is the product that made ARB's name in North America, and the brand supports it the way a driveline component has to be supported: with the setup tools, service parts and spares that let a workshop or a competent mechanic do the job properly instead of improvising. In North America ARB operates from Auburn, Washington as Air Locker Inc., backing every product with a US warranty program. Prestige Truck is an authorized ARB dealer. Every part we ship is a genuine US-market unit with full ARB North America warranty coverage.\u003c\/p\u003e","brand":"ARB","offers":[{"title":"Default Title","offer_id":49118240178420,"sku":"0770003","price":469.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0805\/4784\/0244\/files\/arb-differential-case-spreader-0770003-components.jpg?v=1786480199","url":"https:\/\/prestigetruck.com\/products\/arb-air-locker-differential-case-spreader-0770003","provider":"Prestige Truck","version":"1.0","type":"link"}
