This is a single rear leaf spring (7-leaf 110lbs per inch) for a MGB GT Chrome bumper car 1966 to 1974. Made in the UK for a perfect fit, spring rate and ride height. Beware of cheaper copies that are made off shore that will not have the correct ride height or spring rate. ***Note*** Customer have used these springs on MGB Chrome bumper cars when it was felt a higher spring rate was needed.  ***Two springs are needed per car***
