Harley FX Shovelhead Brake Pedal Spring (OEM #42425-79)
Based on having owned previous versions of this spring in NOS packaging, we know this is OEM #42425-79. Factory references show this part number for FX models (except FXWG) 1979-84.
A different part number is indicated for the 1971-'78 vintage. The early version had a different hook offset. Not sure why the Factory found it necessary to change it for the '79 and later models. Perhaps it had something to do with a new hooking location? Increased tension? We don't know.
