Looks great !
Close tolerance / clearance; if it becomes an issue later on ya’ might want to consider placing bump stops between spring perch(s) and frame rail.
I had a similar problem with a 28,000 GVW boom truck which we installed Hy-rail gear on so it could operate on RR tracks. Because of reduced suspension travel we extended the mounts on bump stops thus eliminating the hitting/rubbing issues.
