Updated "X V2" Pistons
25% Stronger, Updated Washers & Adjustable with Optional Hard Valve (VRP1206).

This is a pack of two VRP 12mm "X V2" Flat Shock Pistons, intended for use with Team Associated 1/10 Scale Off-Road Vehicles equipped with V2 shock shafts (where the piston is attached to the shock shaft with a screw; not an e-clip). "X" pistons are designed to increase the rebound of the shock, without any compression changes, to keep your tires on the surface and in traction.

To achieve this, "X" shocks are designed with a Transition Valve that opens during rebound, but remains closed during compression. As the shock absorbs a force, compression remains the same, but during rebound, additional oil passed through the valve making it quicker.

The pistons come complete with the Transition Valve pre-installed. The Rebound Booster hole has been precision drilled to the exact size 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. 


  • Many piston sizes available
  • Increased rebound 
  • Patent pending design
  • Installed Transition Valve
  • No compression changes
  • No crazy setup changes


NOTE: These fit the Associated V2 Shock Shafts only.

VRP 12mm Associated V2 1/10 "X V2" Shock Piston (2) (1.6mm x 2 Hole)
Simply the best pistons, PERIOD. I have tried just about all the other brands and these offer the best performance and consistency by far. Been running them for over a year now and they are not coming out! Most of my local club racers use them and I have personally seen several top ranked pros using them at bigger races (Phend and Rivkin). As for support, VRP is lightening fast and has a 'No Hassle' policy. Its nice they are in the US and always easy to contact. I have talked directly to Mike who owns VRP and he is a great guy who is all about helping anyone. He helped me with starting oils for my B5m and now my B6, and was spot on! Good thing he Patented the design, by now the rest of the rc parts makers would have copied him for sure!
