Abstract
A portable spring tester adapted for use in testing spring strength for spring assemblies mounted on automobiles and the like. The tester includes a mounting arm for coupling and removably locating the tester in fixed position on the spring assembly. An actuating arm extends from the mounting arm in position to engage with the spring assembly and be shiftable to bias the spring. Engagement surfaces are on the tester for removably mounting a strength indicator thereon so that when the actuating arm is shifted to bias the spring the strength indicator will provide a reading to indicate the spring strength.
