May 21st, 22nd, and 23rd, 2021, will be the dates to the fourth annual Diesel Performance Industry Expo (DPI Expo) at Lucas Oil Raceway in Indianapolis, IN. Our mission is to become the premier diesel performance, aftermarket and specialty products expo in the world. Our first year was a great first step in that direction, with 112 WD, manufactures and dealers exhibiting at the three day event. Once again this year we will be bringing the industry’s leading manufacturers and vendors together, all in one place. With large booth displays and face to face interaction with vendors and engineers, you’ll get the hands on demonstrations and in-depth looks you’ll need to better market and sell to diesel enthusiasts all over the nation. The 2021 DPI Expo will be increasing its size by 35% to add even more industry leaders to its roster to come out and interact with fans and shops
