Approx. +2 if memory serves correctly, I don't recall if they are also +1 forward as well, maybe someone will chime in here in reference to that. There have been numerous threads about this mod in the suspension forums. There are detailed instructions and pics. One guy was selling the spacers for them, and buying and modifying the arms for people. I haven't noticed him on here in a while. These are pretty much ready to go. I had the spacers made alread and had a set of tie-rods made too, They just need to be cut.
