Description With our experience off-roading and building differentials, we have noticed that not all bearings are created equal.  We have hand-selected specific manufactures and specifications to bring your differential to the next level of performance. Note: – The “ARB Lockers” Option has (2) stub shaft bearings and (1) carrier bearing [ARB Lockers come with one bearing installed on the locker] – The “Other” Option has (2) stub shaft bearings and (2) carrier bearings. – One Kit is for one differential
