for anyone to buy it you need to have the eye to eye (the center of one bolt hole to the center of the other) and the stroke (pretty much how long the plungers shaft is between the rubber stopping bushing and the body of the shock) the shock DEFINITELY does not have 4 inches of travel the rear wheel of your bike does.

 you commented on your own picture for someone to buy it, but you have absolutely NO information about the shock in your ad... you have to have all the info i posted in your ad so people know if it will fit and if it will have the right stroke for their frame/ when you say "it has about 4 inches of travel" thats not how far the shock travels at all. the most hardcore downhill shock for frames with 9 inches of travel only have a 3.5" stroke.. thats what im talking about

 somme one buy it
