Hello everyone, this is my first post and I know that there are other threads related to the lst mod but I can't find anything that talks about using the new lst XXL-2 diffs.
I just purchased 2 of these http://www.ebay.com/itm/390894851165 . My question is, is everything that needs to be modified the same as the older XXL difs?
Since the diffs I bought are already complete, will I need to do anything else besides shimming, bulkhead mod etc? I also purchased the output shafts for the axles from rc monster so I have that covered, but what about bearings, will I need to swap the ones that come with the diffs with different ones? I am using mip front and rear shafts and traxx as cvd center shaft. With the traxxas Steel cvd center will I need anything special to connect to the diff? Anything else that i may be missing?
Thanks in advance
Those are complete units so it sounds like you have what you need. You can either grind the bulkheads or grind diff cases. I ground the bulk heads and they don't hold up like that. I plan to go back and redo the install by grinding the cases instead.
I have an RC problem...
Those diffs are the same as the previous version, just new diff case is red. Like rock-rod said you either op grinding the bulks which I don't recommend because it will make them too weak, or grinding the diffs case that's what I did. For the center drive shaft you need to to another mod, you don't need bearings, what you need to swap is the drive cups on the diff for traxxas stubs. Everything is covered on this thread.

Some grinding is involved, I use a dremel little bit little take my time since constantly checking for figment. If you take it too far you might go through the case too.
I followed this thread it helped me a lot when did mine.
I completed the mod a couple weeks ago and I have to say it was a pita but it worked out great! Had to shave both the bulkhead and the case and then it dropped in. To keep it from moving I used hot glue to lock the bad boys in. I probably used 1 - 1 1/2 long sticks for the entire job
