I've had one ton jeeps with big motors and they're quite snappy, but I wanted a rear steer rig with drive shafts out of the way. I have a lot of money in my axles, about $7,500.00 counting steering, $2000.00 for axes, $4000.00 for shafts and lockers, $1500.00 for steering. Add up what it would cost for any other axle that strong and it would be somewhat more I'm sure. I may have to give it a little more gas to climb some things, but for now, that's ok. I ran a 60/44 combo with a big block for years and all I ever broke was front hubs. If I were to build another rig, I would go light every where, axles, motor, and frame. That's the only kind of a rig I haven't had yet! So there.
