Collection: Dieselr Parts

Performance Parts sourced and hand-picked by Dieselr Corp to perfectly compliment Dieselr Tuning custom tunes files.

Dieselr Parts are the real ones. Selected by our in-house mechanics and proven on actual customer trucks — these are the parts we trust to run with our tunes.

This collection includes only Dieselr-sourced parts that directly complement your tuning setup. From the right 4-inch or 5-inch Exhaust Systems that are Downpipe-back or Turbo-back based on your truck's ideal setup to industry standard 4-inch CAT & DPF straight Race Pipes to thick-wall up-pipes and high-flow Y-bridges to sensors, clamps, and switch kits — these aren’t generic catalog fillers. They’re hand-picked by the same people who write your tuning files.

Dieselr Parts are built to hold power, last longer, and solve real-world fitment issues. Every item here is field-tested, not theory-based. That means no guesswork when pairing them with our ECM or TCM tunes. If it’s listed here, it’s because it runs right.

Whether you’re daily driving a Powerstroke or building a Cummins for towing, this is the hardware that keeps it consistent. These parts bridge the gap between your stock truck and a properly tuned machine — without compromising longevity or reliability.

You won’t find fluff in this collection. Just real parts for real builds. That’s the Dieselr difference.
