Is the factory position to put the spacers on top of the frame rail in such that they are just taking up thread space, or is it below the rail to lower the transfer case? I have many trucks and they all have been different.

Transfer case mount spacers

Factory is above the frame, they are to help spread the load on the bolt.
Some people move them under for a cheap way to lower the tcase. The helps the rear driveshaft angle but hurts the front.

also helps blow out the frame rail lips also and make a world of mess to fix later on with a welder / grinder.
to me driveline spacers on our stuff is a cheep bandaid that should not be used . its to help cover up the need for a c/v shaft on the rear that people don't wana pay for .

Good info here. Mine are below and had no idea it was wrong.
I imagine it would also allow some flex at the bolt(s) so the bolts and crossmember can flex with the frame.
Still makes no sense to me. Every other mount on these trucks manages just fine without such spacers...

Steering box
Oops. Yer right. ALMOST every mount survives without the spacers.
the box and middle frame sections tend to get more twisting flexing .
a longer bolt will work with this more before snapping like a short bolt will.
so the spacer gives the longer bolt the way to tighten down and work the way its designed to .

When I got my blazer the spacers where on the bottom of the frame. When I had the rear axle rotated and a CV driveshaft installed I wanted them out. Come to find out when the guy took them out my front drive shaft would hit the cross member at full drop so we just put them back in. They are only a 1/4" or so but it helps the front driveshaft with a 6in lift. I could modify the cross member to clearance the front driveshaft but for now it works.
