These correct shrouded shock absorbers fit BSA A50 and A65 motorcycles from 1962 - 1970. Sold per pair. You can't beat the quality and fit for this price! These shocks measure 14.5" from end to end, 13.5" center-to-center on the mounting eyelets, which accept 3/8" diameter hardware. We have had customers install these shocks on custom Harley-Davidson Sportsters and other bikes. If using for a custom application do your homework and make sure the eyelet inside diameter, length etc will work with your motorcycle.
