Custom Metal Fabrication in Hemet, CA
Custom exhaust, roll cages, brackets, mounts, boost tubing, intercooler piping, chassis fabrication, and one-off metalwork for performance, off-road, and specialty vehicles.
Built-to-Spec Metal Fabrication in Hemet, CA
When off-the-shelf parts do not fit the project, JEP Autoworks can fabricate what is needed. Our metal fabrication work supports performance builds, off-road vehicles, engine swaps, exhaust systems, forced induction projects, specialty vehicles, and long-term custom builds throughout Hemet and the Inland Empire.
Fabrication is often part of a larger build. JEP Autoworks can support the full project with mechanical work, performance planning, dyno verification, paint and body, and final assembly when needed — so fabricated components are built to work with the rest of the build rather than around it.

How Fabrication Fits Into a Build
01
Define the Goal
What the vehicle needs to do determines what gets fabricated. Exhaust routing, cage design, and piping layout all depend on the application — street, strip, off-road, or a combination.
02
Plan Around the Build
Fabricated components need to work with everything else on the vehicle. We plan fitment, clearances, and integration before cutting or welding anything.
03
Build to Spec
Custom work is built to the requirements of the vehicle and the application — not adapted from a generic part that almost fits.
04
Verify Before Completion
Fabricated components are test-fit and verified before final completion. For performance builds, dyno verification is available on-site.
Built Around the Project. Fabrication at JEP is not isolated work. If a build also needs mechanical repairs, performance tuning, paint and body, or dyno verification, we can handle it in the same facility. Fabricated components that are designed and built alongside the rest of the work fit better and function correctly from the start.
