Here is a great alternative to the Koni shock without quite the expense of our Penske shocks. These direct bolt-in aluminum Carrera QA1 Stocker Star shocks are externally adjustable. Simply turn the knob to simultaneously adjust rebound and compression with twelve different settings. Comes with heavy duty nylon incorporated into mounting points already with no need to replace rubber bushings. A completely rebuildable, single adjustable shock at a very attractive price.
