After a year of testing at Thornhill Raceway, VRP is proud to introduce the “Smooth Track’ version of our popular 1/8th XV3 Piston, the XV3-ST. This piston design features a slightly slower rebound stroke matched with an improved ‘connected’ compression stroke, resulting in better handling on smooth surfaces. Just like our XV3 and XV3-HT, this is another option for you to fine tune your suspension from track to track. The ‘ST’ piston was designed specifically for tracks that don’t break up and remain smooth, and range from low to high grip. Featuring our Patented Design, the new ‘ST’ piston is simple and easy to use. It is “plug and play”, simply install and go! The VRP XV3-ST line of pistons are available for all the popular 1/8th vehicles in 5, 6, and 8 holes.
