lockright has been the go to unit for dana 60 for years .
my buddy installed one and he was running 38x12.50x16.5 tsl/sx swampers . he blew a stub shaft out the end of his locking hub . we pulled it and replaced the stub shaft and dial face . been working good ever since no problems with the locker.
we did have to remove 1 side hub/rotor and spindle to slide the shaft out just the amount it needed to install it . there was no cheeting . . and you need a LONG roll pin punch set for the cross shaft roll pin . it only goes in/out 1 way .
