I would humbly disagree with that. Currie/Rockjock is great stuff, but the mid arm is in a league of its own.
Rockjock is a bolt on kit that uses the factory mounts and geometry.
Midarm changes all of that. It’s a weld on kit that changes frame and axle mounts, changes geometry. It triangulates the rear end to remove the track bar. The front changes to a 3 link.
That’s puts the mid arm in a league of its own.
Again Rockjock is great stuff, but to compare the two is a silly concept to me
