About Us
4 STATE TRUCKS
- HOME OF THE -
CHROME SHOP MAFIA
Driven by Tradition. Built for the Long Haul.
Based in Joplin, Missouri, 4 State Trucks is the creative home of the renowned Chrome Shop Mafia — a name made famous nationwide when it appeared on the CMT reality show
Trick My Truck. That show featured our team transforming hardworking truckers’ rigs with expert custom builds, everything done right here in our shop.
Today, we continue to lead the way with the largest custom fabrication shop in Southwest Missouri and host of the signature GBATS (Guilty By Association Truck Show), Missouri’s biggest truck event.
Since 1979, we’ve served the trucking industry with quality parts, accessories, and custom solutions — driven by a legacy that’s both local and nationally recognized.
Serving the Trucking Community for Over 45 Years
What began in 1979 as a small, family-run International truck parts dealership has grown into a trusted source for aftermarket parts, accessories, and custom gear for owner-operators and fleets across the country.
Through decades of change, one thing has never wavered:
Our commitment to keeping America’s rigs rolling — and helping drivers take pride in their ride.
At 4 State Trucks, we’ve come a long way from our early days specializing in replacement mechanical parts. Today, we’re proud to offer one of the industry’s largest selections of aftermarket truck parts, chrome and custom upgrades, collision components, and exclusive in-house brands designed for the professional driver.
As the home of Chrome Shop Mafia, we’ve built a reputation for quality, integrity, and real-world experience — proudly serving the men and women who keep America’s freight moving. Every part we sell and every service we provide is backed by a deep understanding of what it takes to keep trucks on the road and looking their best.
From our roots in Joplin, Missouri, we’ve built a trusted brand that supports the men and women who keep America moving. Whether you’re maintaining your rig, upgrading your style, or chasing that show truck shine, 4 State Trucks is your partner every mile of the way.
