AE V2 12mm Piston, 3 x 1.4 Bevel

These pistons have a 45 degree bevel edge on the bottom side which allows for quicker rebound damping. Lighter rebound damping (rebound= extension) means that the shock can more quickly respond after bumps in the track, keeping the tires from hopping. Also on large jump landings, the lighter rebound damping keeps the wheels on the track as the chassis recovers from bottoming. This translates to added stability and predictablility. Schelle recommends the 3x1.4 in the rear suspension of any 2wd vehicle starting with 30 wt. silicone shock fluid.The additional holes will absorb bumps and give more overall traction compared to a 2x1.6 piston.
