After breaking a 6s shock end by badly landing a jump, I picked up the HD ARA330608 variety. I was surprised to find the wider diameter rod end didn't seem to fit into the HD spring cup. Calipers confirmed the taller HD spring cup had the same diameter as the original shorter non-HD cup. With enough force I can open up the spring cup to fit the HD rod end, but it's not a satisfying fitment. Is this expected, or should there be HD spring cups that are properly designed to take a wider rod end?
Both cups were 5/1000 tighter than the original rod end (.270" vs .275"), but the HD rod end is considerably larger at .315".
If you look closely at the assembled shock, you will see the cup splayed open a bit.
