Is there a way that a Eaton posi can be locked up? I have one in my 12 bolt and needing more traction. I don't want to buy a locker for the 12 bolt because I plan on getting a ff 14 bolt when I wear out my 35's and buy bigger tires. The truck is not a daily driver so no worries there. Just wondering if anyone has done this and if you had any problems doing so. thanks.
