Downward Facing Square U-Bolt Option for Rear Springs

Hard to see because they are the same color, but there is a steel top plate on top of the poly isolator on top. The u bolts are pressing down onto the steel plate, which is deforming the poly isolator under it.

Much better than stock I'd say.
Not sure about the isolators.. steel on steel spring setups have always worked fine for me in the past.

Good job... as well as good job with documentation and photos. :D
Good chance I'll be doing mine very similar to this sometime in the future..

A source for all the parts in kit form if you do not want to use junk yard parts.
https://www.autoandtrucksprings.com/che ... bolt-kits/

The insolators are used to keep the top u-bolt plate from creating a stress point in the leaf.
Eventually causing them to break.

Huh, I figured it was for noise/vibration or something of the sort.

The stock leafs had isolators top and bottom so I just did as GM did :dance:

Also, I will say again that using the under axle saddle things from an astro/safari (2 per side) would be easier than the silverado option I believe. A bit of work to grind/drill the studs out, but less metal work overall probably.

If you are trying to piece together the parts, You may be correct.

There are rubber isolators both top and bottom of the stock springs as well as thin metal sleeves of some sort. I recently took the stock springs completely apart from my 98 parts van and kept all the parts to have when I rebuild my springs. I am rebuilding mine for now and hope to replace with S-10 springs in the future. But I want to do something similar to what Sportsboy did first now then when I can buy new ones its a simple swap.

Should have been that way from the factory IMO.
