Who We Are: Black Diamond Unlimited, Diesel Truck Parts and Performance Near Lubbock

If you've spent any time on the South Plains, you know a truck isn't a toy out here. It pulls cotton trailers, hauls hay, tows the camper to the lake and still has to get you to Lubbock and back on Monday morning. Black Diamond Unlimited was built around trucks like that. We're a diesel truck parts, performance and suspension shop in Ropesville, Texas, about 20 miles southwest of Lubbock, and this blog is where we'll share what we've learned about building trucks that work hard and drive right.

Before we get into install guides and product breakdowns, here's who we are, what we sell and how we can help with your build.

A Diesel Shop Built on the South Plains

Black Diamond Unlimited is built on a simple idea: truck owners deserve parts from brands that stand behind their products, and advice from people who actually know how those parts behave once they're bolted on. Our catalog covers Cummins, Power Stroke and Duramax diesels, plus gas half-tons like the Ram 1500 and Ford F-150, along with Jeep, Toyota, Nissan and Ford Bronco builds.

Whether you're freshening up a high-mileage 5.9 or setting up a brand-new 6.7 for heavy towing, our goal is the same. We want you to get the right part the first time.

Diesel Performance Parts That Make Real-World Power

A good diesel build starts with the basics: clean fuel, plenty of air and an exhaust that lets the engine breathe. Our diesel performance parts are organized around exactly that.

• Fuel systems. Lift pumps and filtration from FASS Fuel Systems, AirDog and Fleece Performance help protect expensive injection pumps and injectors. Browse every option in fuel systems or compare FASS and AirDog lift pumps side by side.
• Air intakes and filters. S&B Filters cold air intakes and replacement filters are a popular first upgrade, especially in West Texas dust.
• Turbos and intercoolers. From drop-in replacements to big single upgrades, we carry Titan Turbos, Fleece Performance and BD Diesel, plus intercoolers and charge pipes.
• Exhaust and engine parts. Shop exhaust systems from BD Diesel, Banks Power and MBRP, and hard parts from No Limit Fabrication for Power Stroke owners who want more than a bolt-on.

Not sure where to start? For most daily-driven, towing diesels, a quality lift pump such as the FASS Titanium Signature Series is one of the smartest investments you can make, because it protects the rest of the fuel system.

Tuning and Diagnostics

Modern diesels are rolling computers, and the right tune can sharpen throttle response, adjust shift points and improve drivability when you're loaded down. We carry tuners and programmers along with the full EZ LYNK lineup and the cables and accessories to go with them.

The EZ LYNK Auto Agent 3 doubles as a diagnostic scan tool, so you can read codes and watch live data from your phone. We also do tuning and diagnostic work at the shop. If your truck is throwing codes or just doesn't feel right, give us a call. One note: emissions rules vary by state and by use, so we'll always help you choose products that are legal for how you drive.

Suspension, Leveling and Towing

Heavy-duty trucks ride stiff from the factory, and adding a winch bumper, heavy flatbed or a loaded toolbox only makes it worse. Our suspension lineup is built around Carli Suspension leveling systems, coils, shocks and track bars, engineered specifically for heavy-duty Ram and Ford trucks.

If you tow or haul, load support matters just as much as ride quality. Air Lift air springs and on-board compressors level the truck under a gooseneck or fifth-wheel and help keep your headlights pointed where they belong.

Kits like the Air Lift LoadLifter 7500 XL Ultimate are a common upgrade for owners who tow regularly.

Lighting, Bumpers and Protection

Dark county roads and early mornings call for real lighting. Our LED lighting section includes light bars, pods and fog lights from Rigid Industries and Baja Designs. Pair them with a heavy-duty Bodyguard bumper and you've got the front end handled.

Inside the cab, Husky Liners floor liners keep mud and caliche off the carpet, and our radar detectors from Uniden help keep long highway drives drama-free.

Brands We Carry

We work with brands we trust, including Fleece Performance, FASS, AirDog, S&B Filters, Banks Power, BD Diesel, Titan Turbos, No Limit Fabrication, EZ LYNK, Carli, Air Lift, Rigid Industries, Baja Designs, Bodyguard, Husky Liners and Uniden. You can see the full list on our brands page.
