YOU DO NOT NEED TO UPGRADE THE BIRFS WITHOUT A FRONT LOCKER I don't know how many times I see this come up but it is totally unneeded. One tire will have a ton of trouble getting enough torque to it to break a birf or anything in the front without a locker. Ironclads friend runs 40" boggers on stockbirfs and hasn't broke one. I ran 36's for a while and beat it hard
