Hell yeah, 22" of linked travel is a ton more effective than the same amount of spring travel, if it were even possible.
Are you bumped out on the frame with the axle tubes, or do you run out of room on the upper link mounts under the bed first ?
By our last measurement we are about .5in away from slamming the bed. If it hits when we put the bed back on we will just need to trim out a 3x6 hole and re-plate it in. Hopefully shouldn't need to but I can't say for sure yet. These pics are at full bump and droop with the shocks so we don't need to notch the frame or anything. The axle is .5 away from hitting the frame so we will build our bump mounts based off this location.
