Additional Diesel Truck Tuning Services

Stock and Modified Engines

Elevate your engine performance with Walls Rod and Custom. We offer modified engines that push beyond factory limits, featuring ported cylinder heads, forged rotating assemblies, and custom pistons. This comprehensive package maintains a stock appearance while providing increased displacement.

Pair your stroked diesel engine with our range of aftermarket options to craft the ultimate tow or race vehicle.

Transmissions and Drivelines

Enhance your transmission‘s longevity and performance with our expertise. We understand that stock transmissions have limitations, and we’ve conducted thorough research to identify potential failure points, sparing you from unpleasant surprises.

Our inventory includes torque converters, transmissions, transfer cases, custom driveshafts, and rear-end parts, providing maximum torque multiplication to efficiently transfer power to the ground. We even stock converters and ready-to-go transmissions, ensuring quick turnarounds within a few days. Experience unparalleled service that you won’t find anywhere else.

Exhaust System Services

Maintaining an optimal exhaust gas temperature is crucial. That’s why our custom tuning solutions often integrate seamlessly with a turbo-back exhaust system. Improving exhaust flow is a foundational step in diesel performance—an affordable enhancement that sets the stage for keeping your truck consistently delivering the performance you anticipate.

Suspension and Lift Kits

From leveling kits and ladder bars to airbag systems and full-scale fabrication projects, we possess the tools and expertise to construct your dream truck from the ground up. We ensure it’s built right the first time.

Fuel System Services

Modern trucks rely on stock fuel systems that must draw fuel through up to 20 feet of line, often requiring additional support. This is where an aftermarket pump becomes essential, delivering high volume to the front of the engine. Beyond increased fuel flow, the advanced filtration of an aftermarket system ensures prolonged injector life and maintains stable injection pressures, ultimately enhancing fuel economy.


Customize your truck to reflect your style. Explore our extensive range, including fender flares, side steps, tonneau covers, brush guards, bumpers, grille inserts, wheels, tires, diff covers, trans pans, gauges, and more—all the latest market trends.

We feature leading brands and hidden gems for a diverse selection. Share your preferences, and we’ll ensure you get the parts that elevate your truck, setting it apart from the rest.
