Slip on or press on drums ?
I'm doing an axle swap to a 14 bolt 1 ton. The axle came without drums. In order to know what disc brake kit to order I need to know if they were slip on or press on. Can you tell by looking at hubs ?

Re: Slip on or press on drums ?
What year is stamped in ring gear is a big help .
But from what i can see on my phone zoomed in there early press on drum . Were the wheel sits there is just 1 surface for the wheel center to register on and center up . If they were slip on drum or even newer disc there would be two lip step . 1 for drum or disc and 1 for wheel . And you look on the back side note the machined lip for the drum to center up . Anymore better option is use a 99-newer 14ff from gas engine trucks . Same basic axle but disc brake AND parking brake . Just need 14x1.5mm lug nuts . And new leaf spring perches and shock mounts . |

NO THERE IS A MAJOR CHANGE
i found this out the hard way 1 time . i had all the parts to go disk from a mid 70's i had with aftermarket kit . i wanted to install on a 96 c3500 truck and the newer with slip on drums and i found out the hard way the spindles are different and the bearings are set a little closer together . and even in the aftermarket world there is 2 specific kits . |

Guy from lugnut told me the only difference in the kit are the rotors and caliper brackets. I was told however the housing after 1988 was 2" wider. No idea if that's true

Ahh yes! I may had forgotten that the slip on drums use different hubs and spindles. I knew the later factory disk spindles where shorter and used different bearing spacing than the pressed drum spindles but I had forgot the slip on drums used the shorter spindle too. Thanks for setting it straight! I went thru all this when I put the 01+ 10.5” 14 bolt factory disk setup on my ‘89 square body 14 bolt pressed drum rear axle. |
