I just ran my new Non Diff-Brain Nero for the first time and I'm all smiles. Really cool truck. But, I gotta tune this center diff as all that monstrous power goes to the front in a hurry. So do I: Seal the diff and use silicone diff oil? Buy the diff brain and just one servo/pin set for the center? (No sure if this will work as all three servos may be needed) JB Weld Any thoughts?
