Here is a veeeeeerrrryyyyy simple 2" drop for the rear shock brackets. The blocks are a basic Nylon plastic spacer that I had kicking around. They are for limiting compression travel on some of the Koni dampers I use.... obviously they work great in the other direction. 4 (2 per side) M10 or 12(???) bolts that are 2" longer than stock hold it all in place...

These would be an easy fab project using some round steel tube of the required length.

they might allow the drive shaft and swaybar to contact at full droop.

Thanks, I'll keep an eye on that... BTW, the swaybar brackets are also lowered.

Brian,
What's the diameter of those spacers?
I'm looking to do something similar.

Thanks,

They have a 1.5" diameter, which is just about perfect given the mounting area.

Brain,

I'm sure you've thought it through, but the plastic spacers look kind of scary. I know the loads aren't huge here, but why not go with schedule 40?

Steel would be the norm for this project... but these have been floating around the garage for a while now, and fit the application perfectly. No cutting/drilling/welding just slap'd em' in, more time for other projects.

As mentioned above, Koni installed these along with a bumpstop to limit compression travel. Made from a solid chunk of Nylon w/ 5/8" hole in the middle....they are made to take the full weight of a truck slamming down on them offroad, which makes them more than up to this task of locating an upper damper mount.

Nylon (cast or extruded nylon 6) is pretty darn strong. The compressive strength is around 14,000 psi and it handles impact loads well. Given a 1.5 inch outer diameter and a 5/8 inch inner diameter each of those spacers should be able to handle a maximum static load of over 20,000 lbs.
