I have had an Idea for adjustable bump stop pads for the Dana 30.
These are my prototypes. These are made from 3" solid round cut to .750 thick 1.5" threading and 2" x.281 wall thread housing. These bolt to the spring pad with a 3/4" grade 8 bolt. adjustable from 5"-7" for taller lifted jeeps

I hope to have installed pics up soon.
