Franks Forks Hard-Chromed Fork Tubes
Our selection of 39 mm Franks Forks tubes is based in the 24.25”(616 mm) tubes that are standard replacement for several OEM applications:

Other models' standard tubes had differing lengths, so e.g.:
- 593 mm (OEM 45381-87): all Sportsters (XLH) 1988-1994 (exc. Hugger 1992-1994), FXLR 1987-1990 and 1994, FXR(S) 1988-1994

Show-chromed vs. Hard chromed
From the chemist's point of view, chrome is always the same: a kind of metal with a defined hardness and resistance against wear. From this point of view no chrome is harder than any other one. The secrets behind the terms show-chromed and hard chromed are
- the preparation of the base, which is chromed, and
- the thickness of the chrome layer.
Show-chrome means a thin layer (up to 1 µm) on a highly polished base. This layer has not the same longevity as the so-called hard chrome, simply due to its lesser thickness.
Hard chroming means applying galvanically a substantially thicker chrome layer on the base. Due to its thickness the finished surface is much more durable and withstands corrosion better than show-chrome.
