Abstract

A slipper-ended leaf spring of fibre-reinforced plastics material has its end portion (10; 30) provided with a covering (11; 31) of plastics material which has been reaction injection moulded onto the spring end portion, to afford a bearing surface (12; 20; 32; 37) for sliding movement. The result is reduced friction and wear at the slipper end of the spring in, e.g. a vehicle suspension.
