Whats the difference between an adjustable shock and a coilover shock?
COILOVERS The word “coilover” has morphed into several different meanings over the last few years. Originally, a coilover shock refered to a racing shock with threads cut into the shock tube. A large nut which served as the lower spring seat screwed down onto the threads. Smaller coilover springs, usually 2.25″ or 2.50″ inside diameter, needed to be used with the shock. In the early 1990s, Ground Control began engineering and producing threaded aluminum sleeves that slipped over KONI, Bilstein, Tokico, etc. performance shock absorbers. The sleeve also had a large nut that served as the lower perch. The sleeve rested on the production spring seat so it would not slide all the way down the shock tube. A smaller 2.5″ racing spring was packaged with the kit. Many other companies jumped into making these coilover sleeves, but did very little engineering work to select their spring rates, or made no attempt to match the spring rates to a suitable sport shock.
