I have a like new set of 5100s that I bought from another member on here that he didn't use for very long because they hit his leaf pack when he flexed. I tried to use them after I put in my all pro leafs and shackles but realized they were too short and would limit travel. I believe these are for stock leafs but I'm not completely sure.
One of the shock bodies has a scratch in it but it doesn't affect performance at all. It functions perfectly just like the other.
Asking 100 shipped obo so don't be afraid to make an offer!
