I currently have a d30/8.8 combo under my jeep. The front has lock rite and chromo shafts, the rear has full spool and chromo shafts. Both are geared to 4.88. I have a hp HD44 and a d60with disc's, and 4.10 gears sitting in my garage. The 44/60 is not bolt in yet. I am running 35's right now and really dont see going bigger. My big reason not to like the d30/8.8 set up is the spool. But i dont want to spend another grand to buy and have a Detroit installed....What to do?
