Rear Shock Opinion

[Wbulk]

I need your opinions on my rear shocks. There are not many guys around that have built one of these B&B cars. It takes some detailed explanation so please bare with me.

I am trying to determine if I have the right rear shocks or were the mounting brackets made wrong. For a few years I have seen other guys B&B builds with the rear shock snap ring in the upper groove. Mine just didn't seem to work that way. With a 10" spring it would make the car set way to high, so I put mine in the lower groove. I have a fender lip to ground height of 28", which looks about right to me. The coil over picture was taken at ride height, on the ground. That 10" spring barely fits at the end of adjustment.

In this process I also realized that my shock is way to close to the end of it's compressed travel. So, do I have the wrong shock or were the mounting points built wrong. Right now the shock ride height is 12.75" eye to eye, but I am not sure which shock I have. The number on the shock is 806990023711 which may be the new QA-1 number 7564; not sure, they are closed until Tuesday. The 7564 shock lengths are 11.43”-17.53”. The center would be about 14.48”, way off from the 12.75” distance I have at ride height. I will take the shocks apart and measure them when I get some time.

I am thinking the upper tab mount looks to low and could be cut off and shorted maybe 3/4", changing my shock ride length to 13.5 at right height. The axle mounting points may be off, who knows. I have about 1" or so between the bump stop and the axle. Another option is to change shocks and go with the 5774 shock which has 10.3"-15.27" measurements, but cost more money. My intention is to go with heavier springs but I wanted to avoid buying new shocks to. . It would be nice to determine why the shocks I got with the kit don’t seem right.

If you have a B&B and know the part number of your QA-1 shocks or can shed some light on this subject it would be helpful.

Thanks.
