I don't believe mine are the short travel ones you're talking about...I honestly don't know for sure but they just look like a regular roller lifter....silver not black...sorry for the ignorance but I really don't remember what they are other than being comp lol

these are what I have...I bought them used....I know I know I shouldn't have used them but the builder inspected them and said there's no reason not to use them and at the time I didn't want to drop the coin on new ones....hindsight obviously I should have but I'm here now
