Re: BDS ROCK-LOCK??
I have the rock lock on my 89 YJ. I installed it myself. It is very easy only takes about an hour to install. Simple to use. Cost was around $200. I recently put an ez locker in my front axle. Now with the rock lock I can have either one front tire engaged or both. So basically, 3 wd or true 4wd, this can help in steering on tight corners. Much better than the old vacuum disconnect.
