The answer is NO. The rear axle provides the bulk of your traction off-road, therefore is the most important axle to lock. The reason is as you climb weight shifts to the rear axle. So you always want to lock the back first. I am sure a front locker will be out eventually, but honestly I dont care. The electronic front LSD is so good I only break traction on the most sevier terrain, and only because I rub the under carrage. I am planning on lift and armor first. This is coming from someone with front and rear lockers on his current trail rig. On my first big wheeling trip I crawled as well as some front and rear locked Xs, and even did better at times!
