Has the WCFab Logo Ever Caught your Eye Scoping a Custom Diesel Build? Find Out What Makes these Parts Worthy of Displaying this Prestigious Name

Under the hood of a diesel enthusiast's truck, across North America, lies a logo that signifies dedication, quality, and a passion for power. That logo is that of Wehrli Custom Fab (WCFab), an automotive company dedicated to serving the diesel community. They pride themselves on ensuring that their products uphold the highest standards of craftsmanship and fitment, worthy of bearing their name. At WCFab, they specialize in high-performance diesel upgrades and custom metal fabrication. They proudly offer MADE IN THE USA turbo kits and custom performance parts for GM Duramax, Ford Powerstroke, and Ram Cummins Diesel trucks. Throughout the catalog at Alligator Performance, you can find an array of WCFab Products, so we wanted to focus your attention on a few that can get you started in giving your diesel truck the full WCFab makeover.

Intake Kits

Anyone that is truly serious about making performance gains will have a premium intake system on their build, otherwise they are just kidding themselves. WCFab Intake Kits are a dependable choice that are guaranteed to deliver maximized power, efficiency, and throttle response. Their Wehrli Stage 3 High Flow Intake Bundle Kit is a must have for GM Duramax owners. It will push your truck's performance well past factory restrictions and create a new, unmatched driving experience. This kit includes a 4" aluminum intake pipe, a 3.5" intake horn with PCV port and surge ring, and an air box enclosure with a dry filter assembly and outerwears pre-filter cover. These precision-engineered parts replace the stock plastic components, significantly improving engine performance and sound. The increased airflow not only boosts horsepower and torque, but also lowers intake temperatures by drawing in cold air from the air duct and inner fender. Crafted with precision, this intake kit features CNC-machined flanges and black anodized billet aluminum adapters with double O-rings, ensuring an improved sealing surface that eliminates boost leaks. The high-quality silicone boots and stainless steel T-bolt clamps enhance durability, even under high boost pressures. Plus, it retains factory connection points and sensors without requiring no tuning.

Traction Bars

It often gets overlooked, but increasing horsepower in your diesel truck can lead to unwanted consequences, like axle twisting, broken u-joints, and damaged driveshafts. WCFab Traction Bars provide the stability and control you need to prevent these issues. They bolt onto the bottom of the axle tube and weld to the frame, offering rock-solid support. All of their kits are manufactured with premium features and backed by a Lifetime Warranty against bending or breaking. Two fantastic examples of their esteemed traction bars that fully showcase this quality and functionality are the Wehrli 60" Traction Bar Kit and Wehrli 68" Traction Bar Kit. What makes these so unique are the high-quality RockJock rebuild-able and grease-able "Johnny Joint" heim connections at the frame. They allow for seamless adjustment of axle torsion or ride height changes. Beyond the high-quality construction of the traction bars themselves, they also have heavy-duty polyurethane bushings at the axle connection that reduce noise and vibration, as well as grade 8 hardware ensures a secure connection to the frame and axle. With either of these traction bars, you will be able to ensure that your truck can handle increased power that comes from other upgrades, while providing a smooth and controlled ride.

Engine Mounts

Are you looking to boost the performance and longevity of your engine? Then you should absolutely be considering WCFab Engine Mounts for adding onto your engine build. One of these seemingly minor upgrades can make a world of difference in your engine's overall health and efficiency, allowing you to unleash its full potential, while ensuring safety and durability. The Wehrli Heavy Duty Engine Mounts offer these benefits to GM Duramax owners. One of its standout features is the incorporation of performance polyurethane bushings. These bushings are designed to provide years of trouble-free operation, surpassing the capabilities of your factory motor mounts. Over time, factory mounts weaken, leading to reduced engine stability, especially on rough terrains. Once these heavy-duty mounts are on your build, you'll instantly notice the difference. Your engine will be more stable, allowing you to confidently push your truck to its limits, especially if you've undertaken a high-powered build. Say goodbye to the headaches of dealing with broken mounts or excessive engine and driveline deflection.
