No worries I wouldnt pull them off to measure them either!
I just find it rather comical they won't share extended and compressed lengths as anyone anywhere can measure this and for most people it's a needed number prior to ordering. Valving is maybe a different story if they don't want to share their secrets with the world.

My shackle barely moves.

It is weird indeed. I emailed King and they gave me extended and collapsed lengths for their OE replacement rear shocks with no questions asked. They even make driver/passenger specific shocks.

I don't think a flip kit necessarily would help more. What you should do is look at how the long travel Bronco/F150 guys run their rear leaves. The use an upward swinging shackle as well. Usually the shackle is bent in the middle, and they use a longer shackle with a highly arched spring. More, smoother travel without getting ridiculous ride height. Honestly wish my first gen Tacoma had your style shackle.

Here is a picture of my shackle with the shocks off. With the Toytec shocks, my articulation seems slightly less. I can tell by the door hanging up. With the shocks off, I had to pull forward to close my door because of misalignment. With the BOSS shocks, I can hear the door hit, but it closes just fine. So I figure the shocks are barely limiting my articulation but at the right point.

Here is the email I finally got from Toytec.
I took awhile and hopefully it is useful.

Ekk. I need atleast 25 extended. You must be very limited in travel with those.

You might be right that a shackle flip may not help much with the same length or stock shackle. I'm happy with being honest about the facts on this, I guess we can wait and see in a few weeks or so, Addison's kit is en route. Member Cam-shaft on his 2005 Tacoma stated he got better droop travel with a shackle flip and they are similar beasts. I spoke with Deaver Spring and they schooled me and pointed out that the 2nd Gen Tacoma and 1st Gen Tundra are difficult platforms to address because of the spring over axle arrangement (if you stay with that), for this reason: the springs are very flat. Spring designers (besides Toyota) do not consider going past flat into negative arch as useable range, and a tidbit I picked up is that the axle starts moving back toward the engine in that range (not really bad). However, the Tacoma and Tundra are perfect candidates for conversion to spring under, large gains in wheel travel come with it. SUA allows you to go from flat springs to much more arched springs all without lifting the truck much. SUA brings a large gain in bump travel because of the distance from normal ride height (significant acrch) to the condition where the spring is compressed to flat (the accepted max compression point).
Most of Expedition Portal members aren't focused on uptravel, they want flex and load capacity. I am game to offer parts that really help owners achieve their goals, that's why the shackle flip idea needs to be tested
Can someone with a loose set of stock springs laying around measure the exact eye-to-eye length? I have a feeling the free length of stock springs are what is limiting droop with stock hanger. Then I can do some figuring and drawings to help see what's really going on.
