ABSTRACT:
The disclosure is of a compressor for the coil spring of a MacPherson strut. It comprises a top force transfer ring and a bottom U-shaped, helical ramp plate secured together in spaced relationship by tie bars. The U-shaped ramp plate is inserted between coils of the spring to surround the central, shock absorber stem. Then when the device is rotated, the ramp plate is threaded down the coil spring to pull it up into the containment between the tie bars. The slight compression of the coil spring in this manner relieves force against the spring mounting to enable repair and or change of the shock absorber.
