This is a pair (2 pistons) of Patented VRP 'XV3' Pistons - 2 Hole 1.7mm Black Flat. The pistons come complete with the Transition Valve pre-installed. The Rebound booster hole has been precision drilled to the exact size our testing found to be the best 'all around' setting. This yields excellent results that are proven on a variety of track surfaces. From rough, blown out tracks, to smooth, indoor clay, the VRP Piston makes a positive difference and gives you a Big Advantage over the competition!
The difference between the Black Flat Pistons and the 'EU White' Pistons is the return rate. The return hole in the EU is smaller then the Black and gives less rebound. This matches up better for higher grip surfaces like carpet and turf.
Simple to understand! The Pistons are designed to increase the Rebound only. They do not change the compression from what you would have running stock 2 hole 1.5 pistons. No crazy set up changes. No scratching your head if they work or even made a difference. Anyone who has run them will tell you it was better from the moment they squeezed the trigger! No questions! ....Amazing!

---- You will feel a difference in the piston because it is designed for the oil to flow through the holes instead of around the perimeter. We suggest starting with the normal oil you would use for this piston size (30-35wt). Remember, the compression stroke stays the same, only the rebound is quicker.
