About Gateway Upfitters

We are a locally owned and operated company that provides vehicle upfit services that include a wide range of truck accessories and protective coatings. We have been in business for more than 24 years. Formerly known as Line-X of Jefferson County and now Gateway Upfitters dba Truck Works STL. Our name has changed, but the staff, ownership, and focus on customer service have not. Over the years, we've had the pleasure of serving the St. Louis community under the Line-X name, and we are grateful for the trust and loyalty you have shown us. As we transition to Gateway Upfitters dba Truck Works STL, we want to assure you that this change is simply a reflection of our continued growth and dedication to meeting your needs. We look forward to the future and providing our customers with the same high-quality products and exceptional service we have always been known for.

After an exhaustive search for our new line of protective coatings, we have decided to go with what we believe to be a superior product line. A 100% USA made product line, along with superior quality and performance, lead us to Phoenix Protective Coatings. Their product line provides us with the highest quality and best performing products on the market. The bed liners are backed by a Nationwide Lifetime Warranty that our customers have come to expect. My team and I are confident in the high-quality coatings we are spraying and proudly put our name on everything we do. We are excited to be working with a company who truly cares about the products they sell and the companies to whom they sell. Our focus moving forward will be to continue to provide our customers with unmatched service and superior quality.
