Shop by truck

Most of our customers drive heavy-duty diesels and half-tons. Start with your truck to see parts listed for it: Ram and Dodge, Ford, Chevy and GMC, Jeep Wrangler and Gladiator, Toyota and Nissan. Diesel owners can go straight to Cummins, Power Stroke or Duramax parts.

Why South Plains drivers call us

Trucks around Lubbock pull stock trailers, haul cotton modules and campers, and run caliche roads and long stretches of highway. That shapes what we recommend: dependable fuel supply and clean air for diesels, load support for towing, real lighting for dark county roads and covers that keep dust and rain out of the bed. Tell us your year, make, model, engine and how you use the truck, and we'll help you choose parts that fit before you order.

Areas we serve

We're on US Highway 62 in Ropesville, about 20 miles southwest of Lubbock between Wolfforth and Brownfield.
