This is an optional Competition Suspension Blue 12mm VOP Piston Set. Competition Suspension has once again raised the bar when it comes to suspension technology and performance. CSI's VOP (Varying Oval Port) 12mm shock pistons feature some unique design elements that help to maximize both shock and vehicle performance.

CSI's VOP engineered pistons feature CSI's varying port design that was introduced to 1/8 off-road racing a few years ago and has proven to be the industry standard for maximum shock performance. CSI's VOP tapered oval port 12mm pistons provide separate damping forces for compression and rebound, depending on which way the piston is installed. CSI's 4 port VOP design provides optimum low and high speed damping, giving the racer a larger tuning window for track conditions. Due to CSI's unique design, the VOP piston reacts faster to velocity changes, improving overall traction and handling on any track surface.

CSI's 12mm VOP pistons are available in two flow rates:

  • CSI Blue VOP Piston: High to medium bite surface. Smooth to average track conditions (Indoor). Recommended Starting Range: (27.5wt to 32.5wt)
  • CSI Red VOP Piston (CSI-CRP-0005): Medium to Low bite surface. Average to rough track conditions (Outdoor). Recommended Starting Range: (37.5wt to 42.5wt)
Blue VOP Piston Installation:
  • High bite smooth surface = flat side of piston facing down
  • Medium to low bite, rougher track surface = Flat side of piston facing up
