HAL Shocks has the single best shock available for street, strip, or handling -- this is the shock that can do it all!  Valving adjustments are made with the click of a knob at the base of these billet aluminum shocks (12 settings total), allowing you to adjust to changing special applications from drag racing and road racing to everyday street use. This shock is the dominant force in Super Stock and Stock classes. New "Stocker Star" R-Series Drag Race Shocks feature a fixed-firm compression with an adjustable rebound.
