Guys, What's everyone's opinions on Longfields and the version with and without rings? I've got a 2F and stock axles. May drop a 350 in down the road, depending on what I determine the cost to be to rebuild the 2F. Suspect I'll need to do something within the next 6 months. Runing 33" M/T now, but will most likely go to 35's if I drop in a 350. I'm sure I don't need the Longfields right at the moment, but would rather prevent a problem before breaking somewhere. Rings or no rings?
