those are them, either length will work in the GRiSO, if yoy notice the extra length is in the shock shaft. both have the same length bottomed, just different extended... this is why this is the way to get the rear up and get a good ride from the GRiSO...it is a wonderful improvement in hdling to have the long stroke shock on the GRiSO you can run lowered pegs without scraping them like happens when you raise the front in the triples, this mod is good for about 1.3" (the stella shock works turned backwards
