$100 for assembly was a good deal. The KYB upper mounts that Shock Surplus uses are now $70 each.
My 6112s are on backorder for another month so I'm getting things figured out now.
The OEM studs protrude about 3/4" but that huge flange nut eats up about 1/2" of it. Adding a single 3/8" thick spacer would leave no threads showing.
Another member on the forum advised me that swapping from OEM upper mounts to KYB would take care of it. So I ordered one of the KYB tops to check the stud length. If it is longer, great - but if it turns out to be the same as OEM, the solution must lie in using a thinner nut because some folks on here are running double 3/8" spacers. Ideally I would like to do the same, plus set the clip in the 1/2" lift position for 1-1/2" total.
Worst case I'll set the 6112's for 1" and add a single spacer.
I was second notch from the top on my old truck with 5100s and it rode like a shopping cart. This Tremor is so comfortable. I'd like to preserve as much of that as possible.
