    This thing is located right below the starter, making access to it darn near impossible. It also makes three bumpstops on the passanger side. Is it really needed? IF the suspension could compress enough, it would "land" (maybe hit is a better word) on a flange on the pumpkin right next to the pinion.

    I'm thinking either /forums/images/graemlins/hack.gif or /forums/images/graemlins/weld.gif ...Thoughts???

    I pulled mine off.

    Assuming since there is already a stop for the axle tube, this one is to keep the pinion from rotating up when the axle is stuffed up. Sounds good anyway. /forums/images/graemlins/smile.gif

    I've often wondered what the hell they were there for as well. /forums/images/graemlins/ears.gif One of mine fell off the other day. Maybe it was somethin to help with the stock spring setup? I dunno.

    With lift springs the stock bumpstops are pretty much useless. As far as I can tell the original design was for the rear most stop to touch the springs first, this 'raised' the spring rate during heavy hits. The front most stop was the normal bottom out stop to keep the axle out of the oil pan. The single bumpstop over the diff kept the diff from kicking up into the oil pan/starter area. Kinda goofey huh.

    GM added that bump stop in later years, to serve but one purpose. If you skyed a stock truck just right and then landed hard on the right front, it would shove the axle up high enough to snap the starter right off the block. /forums/images/graemlins/eek.gif
