ARB 0770003 | Differential Conversion Spacer

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.

Today, we supply and manufacture a complete selection of the most highly regarded 4WD accessories in the world. Unlike many 4x4 equipment suppliers that simply stock a collection of parts with a low cost, `one size fits all' mentality, ARB thoroughly researches and tests each product before releasing it to the 4x4 public. We consider many factors during this analysis, including specific vehicle characteristics, the conditions the product will work in, and the overall quality of the product itself. Take suspension systems for example. Many aftermarket 4x4 suspension kits ignore the obvious differences between varying vehicle suspension set-ups and driver requirements, offering instead an increased ride height and little else. ARB's Old Man Emu suspension division employs a very different approach. Typically our OME engineers will purchase the vehicle in question, test it in a variety of conditions to determine if and where improvements can be made, then develop a line of finely tuned, totally integrated suspension systems, each offering varying degrees of comfort, load carrying capability and control characteristics. When combined with our state-of-the-art manufacturing plants and a highly skilled workforce, this attention to detail is what sets ARB 4x4 equipment apart. So whether you're new to 4WDing and putting your first truck to the test, or a 4x4 veteran getting set for your next off road adventure, you can rely on ARB 4x4 Accessories. we won't let you down.
