Abstract
An annular nut cooperates with threaded sectors, which are formed on the reservoir tube of a shock absorber having a coil over spring preload, to provide for adjustment of the preload. The threaded sectors are equispaced angularly about the longitudinal axis of the reservoir tube of the shock absorber, and the threads of the threaded sectors are disposed in the planes that are substantially traverse to the longitudinal axis of the reservoir tube. The annular nut abuts the adjacent end of the coil over spring and the spring end is attached to the nut so that the spring and annular nut rotate together.
