The first stabilizer bar patent was awarded to Canadian inventor Stephen Coleman of Fredericton,
New Brunswick on April 22, 1919.
Sway bars were uncommon on pre-
WWII cars due to stiffer suspension designs at the time,
but they became widely fitted on production cars starting from the 1950s,
especially those with softer coil spring suspensions.
