603 Diesels started in 2014 as a small group of friends gathering in local parking lots — a place where truck enthusiasts could meet, make friends, and talk about their builds. Over the last 11 years, that simple idea has grown into the largest truck meet community in New England. Today, we proudly host events where anyone, no matter what they drive, can feel welcome and part of something bigger.

Our mission is simple: "Fueling the Next Generation of Motorsport Enthusiasts."
We are passionate about creating unique, well-rounded events that offer something for everyone — drag racing, show trucks, dyno runs, burnout competitions, vendors, tailgating, and more. Whether you drive diesel, gas, or anything with a motor, there’s a spot for you at 603 Diesels.

-

But we’re more than just events. We’re committed to building a positive and respected reputation for the truck and motorsports community. We proudly support local racetracks, venues, small businesses, and vendors — many of our apparel items are produced right here in New Hampshire. By working closely with dozens of local businesses and venues, we help keep these vital parts of our industry alive and thriving.

603 Diesels also serves as a platform to uplift others, give back, and encourage our entire community to do the same. We’re proud to be family- and dog-friendly, bringing together enthusiasts of all ages — from kids to retirees — under one common passion.

-

Through respect for our venues, staff, law enforcement, surrounding towns, and fellow enthusiasts, we strive to create a safe, fun and welcoming environment for everyone to make memories at.

At 603 Diesels, we’re not just racing — we’re building a movement, a culture, and a family.
