A Legacy of Power and Precision

Say When Motorsports was founded by Nick Shuffield, a lifelong diesel mechanic with nearly 30 years of hands-on experience in the automotive and performance industry. What started as a passion project quickly evolved into one of Arkansas’s most trusted names in diesel and performance customization. For over 12 years, Nick has grown Say When Motorsports into a full-scale mechanical and tuning shop known across the state for reliable work, fair pricing, and jaw-dropping builds.

Nick doesn’t just run the shop — he’s in it every day, working alongside the crew, tuning engines, building custom machines, and ensuring every vehicle that leaves Say When Motorsports meets the highest standards of performance and safety.

Low Shop Rates Without Cutting Corners

At Say When Motorsports, we believe you shouldn’t have to overpay for top-quality work. That’s why we keep our shop rates lower than most in the industry. We focus on transparency and fairness — with no inflated pricing, no unnecessary upsells, and no shortcuts when it comes to doing the job right. Whether you’re getting a simple diagnostic or a full engine swap, you’ll get honest pricing and dependable service every time.

Performance Tunes that Push the Limits

Performance tuning is more than just uploading software — it’s about understanding your vehicle, your goals, and how to safely push the machine to its max potential. We specialize in custom performance tunes for Power Stroke, Duramax, and Cummins platforms — increasing horsepower, torque, and throttle response without compromising reliability. From daily drivers to full-blown race trucks, we can tailor your tune to fit your build, needs, and driving style.

Known Across Arkansas for Side-by-Side Builds

Say When Motorsports has earned a statewide reputation for our custom side-by-side builds. From suspension lifts and roll cages to lighting, sound, engine upgrades, and full trail-ready setups — we build machines that dominate at the dunes, on the trails, and everywhere in between. Whether you’ve got a Polaris, Can-Am, Honda, or Yamaha, we can turn your ride into something wild — with real performance and dependability.

Meet the Team Behind the Wrenches

Our shop is powered by a team of four full-time, specialized mechanics — each of whom brings years of experience in diesel, performance, and off-road customization. These aren’t just general techs — they’re specialists trained in modern diagnostics, engine tuning, electrical systems, suspension setup, and performance fabrication. Every build and repair benefits from their combined expertise, attention to detail, and passion for automotive excellence.

We’re not just turning wrenches — we’re building relationships with our customers, one honest job at a time.
