The Eaton / Spicer 813575 is a left-hand outer nut used in differential assemblies on heavy-duty truck axles. Left-hand thread nuts are position-specific and must be matched to the correct side of the axle assembly, substituting a standard right-hand nut will not seat correctly and can cause axle-end failure. Sold individually. Pro Gear and Transmission carries genuine Eaton and Spicer differential hardware. Call us to confirm this is the correct nut for your axle and differential configuration before ordering.
