Sorry to say I don't know for sure, but I would contact the vendors directly. I'm sure they could answer that for you. On a side note, it seems the trackick/vit aluminum front diff housing is a big issue for alot of ppl, it tends to break under heavy use/offroading etc. There is a mod where ppl use a sammy steel housing & modify it to fit trackick front mount & install the trackick carrier into it. It also stands up to lockers better from what I've read. Cmays07 recently posted about his broken front diff, & his pics look alot like others who have had similar experience. This site tends to be more OEM repair & not as much into the modding end of things. Here's a link that may help:
