These fork tubes fit any model Harley with a 39mm front end on it. You can buy any length 39mm fork tubes you would like, as they mount up the same on all models. These fork tubes are 39mm in diameter and measure 23-3/8” long. Chrome plated finish.
Sportsters 1986 through 2003 have fork tubes that are 23-1/4”, 23-3/8”, or 24-1/4” long, depending on what model they are on. This is a variation of 1”, maximum.
