This is an adjustable front shock Set (2) for a Triumph TR3 and TR4. You get 28 adjustments that can be made while on the car. Each unit is made to the highest standards of construction and are stout enough for competition use or general street application. Non-corrosive plastic boots top the SPAX shocks. With the screw-type adjuster, a clockwise turn will increase the rebound dampening and counter-clockwise turn has the opposite affect for wear or for the demands of competition. The external adjuster can be accessed while the shocks are on the car. G209
