Am I right on saying the vehicle is a part time 4x4 with open diffs? What is your opinion on the best way/best lock to add to lock up the rear or front diff. Open diffs just do not cut it. I was wondering why my 100 outperformed this 40 and open diffs would certainly scream that answer. By the way, I am familiar with ARB lockers, locktites, lockrites detroits. Just wanted to hear from the field. Thanks.
