280z4me2 Posted January 11, 2013 Share Posted January 11, 2013 Got my rear end dropped and have an OBX unit I will be dropping in in place of the stock open diff in my r200. Do you guys normally follow the steps on checking and adjusting backlash or do you just bolt it in with the same shims? Also, easiest way to check gear ratios in two different r200 sitting on the work bench? Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted January 11, 2013 Share Posted January 11, 2013 If the diffs are on your work bench, the easiest way to check the ratios is to pull the covers and look for the stamping on the ring gear. In fact, it is the ONLY way to be sure what your ratio is. Quote Link to comment Share on other sites More sharing options...
280z4me2 Posted January 12, 2013 Author Share Posted January 12, 2013 Great! Any tips on the diff swap? Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted January 12, 2013 Share Posted January 12, 2013 Don't know anything about an OBX-I've only done the Z31 differential. I don't know anything about setting up any of the lash or gear engagement. I've only done an uneducated plug and play. Quote Link to comment Share on other sites More sharing options...

Lazeum Posted January 12, 2013 Share Posted January 12, 2013 Couldn't resist as I've seen many topics on this http://lmgtfy.com/?q=obx+lsd+hybridz.org I love your link, I'll keep that in mind for me as well. To the OP, there's a thread full of great info on OBX diff. It is in the FAQ. Quote Link to comment Share on other sites More sharing options...
heavy85 Posted January 12, 2013 Share Posted January 12, 2013 I had to shim the OBX differently than the factory lsd it replaced so at least for me it wasnt plug and play. Cameron Quote Link to comment Share on other sites More sharing options...
