The LT used a Fox Vanilla RC coil shock with a 57mm stroke, if it’s got a 5th element, Fox R or RS unit then its a 5 inch travel version, The Fox RC was the only shock ever specc’ed that was available with a 57mm stroke, there were no changes to LT frames other than removing canti bosses to stop V brakes contacting the seattube under full compression. if you can find a 190/57 Fox RC its an easy upgrade to make provided you run discs.
