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:
- OEM 45407-86 on all Sportsters (XLH) 1986-1987 and FXR(S) late 1986-1987
- OEM 45395-92 on XLH Hugger 1992-1994 and 1999-2003 as well as all XLH (exc. 1200S) 1995-1996 and
- OEM 45360-90 on all Dyna 1991-1992 and FXDL 1993-2000.
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
- 644 mm (OEM 45393-87): FXRS-SP 1987-1990 and 1993-1994, FXRS-CON and FXRT 1988-1994.
To choose the right tube length we recommend measuring and comparing your old tubes.
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.
