Welcome to the new and improved Proflex / K2 Tech Forum!
Colin,would it be correct to spec both shocks at 8.5"/2.5" with different spring rates between front and rear ? The spring rates listed by the documents you mentioned would be valid with any other shock from other manufacturers? Thanks a bunch for your help!
My bike is a K2 4000, the mounts, while of different sizes, are of the same type.
