I'm just not fond of rotating the shock to a different position from its intended use. I also don't have much confidence with the way it is oriented. Feels like the extender could rotate on the bolt if the shock failed to compress.

The extenders made for lowering always look to have much better mounting orientations that almost appear to lock into the stock mounting bracket.

Maybe finding an example of someone using them would give me more confidence, but I can't seem to find any. Saw a review on Amazon for a pair like the ones I linked to where a guy said they didn't work for him because of the rotation of the shock. He said he got a set from BellTech that had a better mount, but I can't find any on their site.

the part of the shock that needs to rotate can spin around freely with no issue.

i do agree that they look chinsy as hell, though. But should be just fine.

Good to know that. I think I'm gonna shop around for some 2" spacers and some shock extenders that look less likely to move under stress.

Found something interesting while searching around yesterday. ReadyLift makes a set of shock extenders that are similar to others I've seen except they are rounded (https://www.readylift.com/rear-shock-extensions-gm-full-size-truck-suv-1500-1999-2018.html). I think that would be even worse as far as possibly moving under stress. However, reading through the questions posted on their website showed this question and answer which has me curious.

Do these rear shock extensions get installed on the top or bottom of the shock? Thanks in advance."

ReadyLift's answer: They mount to the top at the frame.

I've always thought these were mounted at the bottom and have even seen YouTube videos of them mounted at the bottom. This is the first I've heard of mounting them at the top. I don't remember exactly what the mount point looks like at the top, but I remember it being a pain in the ass to get to it. I may get under the vehicle tonight to see if that seems like a more stable location for the extenders.

In looking at how these are designed to be used and how forces are carried through the shock, I have concerns about the longevity of the shock when using these.

In a normal set up, you have two pivots that are parallel with each other and a rigid body (the shock) between them so any force is a pure in-line force on the shock and the load is distributed across the width of the bushing.

With the extender, you now have the pivots on the shock oriented perpendicular and there is a chance that the center-line of that pivot is not on the center-line that exists between the upper body mount and the lower axle mount, which will put the upper shock bushing in an unequally loaded situation where it has to resist the tendency of this set-up to buckle. The bushing is not designed for that concentrated load, but instead for a load that is spread across the full width. Even if the bushing can handle the load, this is putting excess side load on the bushing/seals of the shock as they will see and have to carry that possible buckling load as well.
