I run my 06 s-works stumpjumper with the Float RL (with ITCH switch) off my old 03 Enduro. According to specialized it measures 7.625″ x 2.0″.
Whilst it fits, it does tend to foul on the weld on the linkage which i’ve found tends to put extra force on the lower bushes. This means i have to replace the lower bush pretty much every 8-10 rides?? I’m currently trying a stainless strong bush that i’m hoping will last a bit longer
I’ve also found that the extra shock length has screwed the geometry up a fair bit even with a 130mm fork up front. Whilst it’s cracking on the cross country i always feel like i’m sat over the front wheel when it comes to the steep downhill’s.
Hope this helps!!
