ABSTRACT:
A coil spring compressing tool for use in compressing suspension springs of cars and trucks includes a pair of elongated rectangular blocks extending in spaced parallel relation. A pair of parallel guide rods are slidably received through aligned apertures provided adjacent opposite end portions on each of the blocks. An enlarged retaining stop is secured at each end of each of the guide rods for limiting maximum separation of the blocks. An elongated threaded rod has a first end portion received for free rotation in a central bore formed through one of the blocks and a second end portion in threaded engagement with a threaded bore formed centrally through the other block. A driving head is provided on an end portion of the threaded rod for engagement with a wrench. A pair of oppositely directed hooks are secured at aligned positions on side faces of the blocks and are dimensioned for engagement with a coil spring. Rotation of the threaded rod causes the blocks to move together to compress a coil spring.
