I did not pay much attention to the plentiful N74L threads over on ih8mud, but I think there are some additional considerations with this shock (experts feel free to jump in and correct me). Are you going retain the top (pain) and bottom of the springs? With the taller 863 spring you need to retain the bottom, and I believe with the shorter 864 you would need to retain both the top and bottom. Also, I'm not sure if you need to lengthen your swaybar links to actually use the extra travel, and I think will have to lower you bump stops even with 33's so you don't damage the shock on the compression stroke.
I ended up skipping N74L because I thought I would eventually work my way from the 863's to 864's w/ spacers and I did not to want to go through the hassle of retaining the 864's.
Hey Tom
This is going to be a trial and error mod and i will be testing soon and adjusting as needed. If needed, i will retain the springs and lower the bump stops.
Also, i believe the 864's are taller then the 863's, from slees site (listed as same height, but 864's are stiffer, hence taller, less sag):
OME860 | 2.5" | 0-200 lbs
OME862 | 0.75" | 0-200 lbs
OME863 | 2.5" | 200-440 lbs
OME863J| 3.5" |200-440 lbs
OME864 | 2.5" | 300-600 lbs
Thanks
