Hi guys,

Ive bought a hub to hub rear end from a SF 80 coz I wanted the air locker. I have a late model FF rear didnt think about till after I got it. is this going to work? id rather not swap the whole thing and go from FF to SF.

What are the chances I could use the air locker in my existing diff? are they different or the same?
 
They're a different part number - SF is RD153 and FF is RD142
 
the difference isnt in the diff centre of a sf an ff rear end though is it?

theres no solution other than swapping in the sf for ff full rear end?
 
Diff centre doesn't dictate FF vs SF but SF axle has circlips to hold the axles in and the locker will need provision to accept these.
 
Yes, the SF ARB will work in a FF axle. It will have the c-clip provisions but that won’t stop you from installing it in a full-float axle.
