Output shaft nut Spanner Socket


“WOW!”  That may be your thought when you first take this out of the box.  


Our T-1000AC  is milled from tough AISI 1018 steel.


 Accepting a 1/2” drive and weighing in at just over 25oz,  our socket is more than just another pretty face.  The inner cavity is cut only slightly larger than the output shaft as to eliminate any possibility of side-loading the ears, shortening its service life, eventually slipping and rounding the uncommon spanner nut: a sure way to ruin your day.

Also fits
GM 4X4
NV4500!
