Felder Kustom Fabrication: Performance Parts Built for Diesel Enthusiasts
For diesel truck owners who want more performance, durability, and a custom look under the hood, quality fabrication makes all the difference. That’s where Felder Kustom Fabrication comes in. Known for producing high-quality aftermarket components for popular diesel platforms, the company focuses on parts that combine performance, reliability, and practical design.
Felder Kustom Fabrication designs and manufactures components for diesel pickups including Duramax, Cummins, and Powerstroke engines. The goal is straightforward: provide performance-driven parts that are built to last while keeping them at a reasonable price point. From turbo kits and traction bars to fuse box covers and intake components, the product line continues to grow with new upgrades being added regularly.
Below is a closer look at a few standout products currently available from the company.
High-Performance S400 Turbo Kit for the LB7 Duramax
One of the most popular upgrades available from Felder Kustom Fabrication is the 2001–2004 LB7 Duramax S400 Turbo Kit. This kit is designed for diesel owners who want to unlock serious power while maintaining reliability.
The system is built using high-quality materials and components that ensure durability under heavy boost and demanding driving conditions. FK Fab turbo kits utilize TNT4R turbos, along with BSI Inc. V-bands, providing strong and reliable connections throughout the system.
Each turbo kit also includes essential supporting components such as:
- Complete turbo completion hardware
- Wastegates for boost control
- Turbo drains
- Proper mounting components and fittings
This complete setup makes it easier for diesel enthusiasts to install a high-performance turbo system without piecing together parts from multiple sources. The result is improved airflow, increased power potential, and a cleaner overall engine bay layout.
2019–2023 Cummins High Mount 2nd Gen (2G) Swap Kit
For Cummins owners looking to move away from the factory VGT turbo setup and step into the world of high-performance fixed geometry turbos, the 2019–2023 Cummins High Mount 2nd Gen (2G) Swap Kit from Felder Kustom Fabrication offers a complete and well-engineered solution.
This kit is designed to provide everything needed to perform a 2nd generation turbo swap on modern Cummins trucks. Built with performance and fitment in mind, it combines durable materials, smart routing, and a clean installation process for diesel enthusiasts aiming to increase reliability and power potential.
Designed for Performance and Fitment
At the heart of the system is a set of carefully fabricated components that work together to support high-performance turbo setups. The kit includes a 4-inch 304 stainless steel downpipe, which connects directly to the factory 4-inch exhaust system without requiring cutting. It also comes with TI heat wrap to help manage temperatures in the engine bay. This photo features a BSI Inc. T4 turbo blanket.
Duramax Bolt-On Tube Style Traction Bars
Power upgrades are only part of building a capable diesel truck. Controlling that power is just as important, especially for trucks that see heavy towing, racing, or aggressive driving.
The 2001–2010 Duramax Bolt-On Tube Style Traction Bars from Felder Kustom Fabrication are designed to reduce axle wrap and improve traction. When trucks produce high torque levels, the rear axle can twist under load, which leads to wheel hop and lost traction. Traction bars help stabilize the rear suspension and keep the truck planted.
For diesel enthusiasts pushing their trucks beyond factory power levels, traction bars are an essential upgrade that helps maintain control and protect drivetrain components.
Custom Fuse Box Cover for 2015–2019 GM Trucks
Performance upgrades are important, but many truck owners also want their engine bay to look as clean as it performs. The 2015–2019 GM Fuse Box Cover from Felder Kustom Fabrication offers a simple way to elevate the appearance of the engine compartment.
This custom cover is designed to fit neatly over the factory fuse box, creating a cleaner and more refined under-hood look. Fabricated with attention to detail, it’s a subtle upgrade that helps tie together other aftermarket components and custom engine bay builds.
For truck owners who attend shows or simply take pride in their vehicles, small details like this can make a big visual impact.
Built by Diesel Enthusiasts
Felder Kustom Fabrication’s product lineup reflects a deep understanding of diesel performance. The company focuses on creating practical upgrades that truck owners actually need, whether that means improving airflow, strengthening suspension components, or enhancing the appearance of the engine bay.
Their growing catalogue includes products such as:
- Turbo kits
- Fuse box covers
- Exhaust tips
- Traction bars
- Brake reservoir covers

New products are continually being developed, allowing diesel owners to upgrade their trucks with parts that are purpose-built for performance and durability.

Diesel enthusiasts have another exciting product to look forward to this spring. Felder Kustom Fabrication will soon be releasing a 2017–2026 L5P Duramax S400 Turbo Kit, designed specifically for the latest generation of Duramax engines.
This upcoming kit features premium construction and performance-focused design elements, including:
