Well I just regeared to 4.88's locked f/r running 33's. Is it low enough to where you dont even have to really use the gas sometimes or what? I should probably get some chromoly birfs too huh? Especially going that low and having that much torque. I haven't broken one yet but have stock for spares.
I have been running my original, stock 85 birfs in the front since I got the truck 4 years ago. Now I have duals and a rear lincoln locker and have ran both Fordyce and Rubicon with them no problem. As long as you don't beat your front end and hammer down with the wheels fully cranked and in a bind, stock birfs are fine. When I can afford it I will update to Longfields but I treat my truck pretty good and don't beat her if I don't have to.
