Then something else is stopping the suspension travel. Find it and decide if you want to move past it. If not, then your shocks are too short.The shock appears to have more travel left at full compression. I’ll confirm. ...
...And might add a 1” no matter what for a safety factor. (Is that crazy or over cautious)
That is needlessly cautious and only cripples the suspension. Make the shocks the final limit to up travel. Then extend the bumps enough to make the jounces do their job of slowing the last bit of travel.
Once I get the springs installed I’ll confirm ride height and travel distances
By now you should be seeing that the are several things going on at once in this balancing act. Your goal is ~50/50 shock travel at ride height.
Thanks. I think I’m almost there.
Keep at it! You are going through a process that will help set your build apart from many others.
