Here is the picture.
The front are the 186872.
Rears are 186887.
I don't know, I figured they would unseat. Not by much. I also have 3" coils, 3" bump stops, my shocks are close to 17" collapsed. I also have my lower shock raised another 1/2" with my relocation brackets. At full bump I have extra ½" of shaft showing.
These measurements are the Fox 4-6 inch shocks. I will be using them with EVO 3" coils.
