Compresseur de ressor hélicoïdale

Coil-spring compressors are essential for removing and refitting coil springs in suspension systems. A compressor is usually a long, threaded bolt with a hooked section at each end that fits over the coil. You need a pair - one for each side of the spring, or even three for large diameter springs. Always use good-quality compressors, or the bolts may strip under pressure. They can be hired.
