super super important to get he bump stop to stop the wheels when the steering box stops. This takes any stress off the frame ie dodge trucks. It also prevents a steering box from cratering. Such as a broken sector shaft. This only happens when the steering is dead ended with the steering arm bottoming the gears out inside the box. Many arguments have been made that the weak steering box just let go gently wheeling down the trail. This can happen. However the shaft was fractured previously and can hold on for a long time just letting go later on.
Once you move into hydro assist the ram should match the throw of the box which should already match the motion of the knuckles from stop to stop. Once again if the stroke is greater than the distance the knuckles can travel when the ram bottoms out and pushes the ball joints/ king pins apart. At which point you'll bitch about how crappy your ball joints are. Also it will flex the center section and possibly warp it. On diffs with casted centers such as 60's this creates different pre load on the side bearings leading to gear failure.
Full hydro is a bit easier match the ram stroke to the desired degree you'd like to see out of you knuckles lock to lock. Obviously without binding the axle u joint.
A simple bolt won't work. You need to actually make something that can handle a hit. I've seen the bolt style flatten beyond recognition. Keep in mind that even if you think the ram is doing the job if a joint, arm link etc... let go and that knuckle flops out the stops will prevent hyper extension which again leads to stretched inner C's wrecked inner and outer shafts broken knuckles etc....
