This auction is for a 6061 aluminum CNC machined spanner wrench for adjusting the bigger (Preload) collar for a 2.5" shock. The collar should look just like the one pictured with the holes in it.
This is a clone of fox part number 803-00-732 and will fit anything it will fit
 The wrench features a hardened pin and contoured corners so its nice on your hands. 
This is uncoated. This item is built strong, I put 150 pounds against the wrench and it had no problem with it.
