🔧 UNDERGROUND AUTOSPORTS IS HIRING 🔧

We’re looking for an experienced **Automotive Technician** to join our team at Underground Autosports in Zion, Illinois.

We work on everything from performance builds and modified street cars to diagnostics, suspension, brakes, engine work, and custom projects.

**We’re looking for someone who:**

• Has solid professional automotive repair experience
• Can diagnose problems—not just replace parts
• Takes pride in doing the job right the first time
• Pays attention to the details that matter
• Can work independently and as part of a team
• Keeps their workspace organized and respects customer vehicles
• Is dependable, professional, and actually wants to be here

Performance experience is a **big plus**, especially with LS/LT, Gen III , Mopar , Modified Vehicles, and Aftermarket Components—but we’re willing to talk to the right technician with a strong mechanical foundation.

We have a busy shop, some seriously cool projects, an in-house dyno, custom fabrication, performance tuning, and plenty of opportunity for someone who wants to grow their skills.

📍 **Zion, Illinois**
💰 **Pay based on experience and skill level**
🛠️ **Full-time position**

Think you’d be a good fit—or know someone who would?

**Send us a message with your experience and resume, email your resume to our AMAZING HR Manager, Gretchen, [email protected]
OR

This 1500 came in for a custom engine and transmission tune—and you can hear the difference. 🔥

Crisp, firm shifts. Better throttle response. Improved drivability. No canned tune—just a calibration built specifically for this truck.

This 2014 Jeep SRT8 didn't just show up for a supercharger and hope for the best.
The owner did what many people skip—he built the foundation first.


✅ FED Ported Heads
✅ LTH
✅ Supercharger

The result?
A brutally responsive, hard-charging that pulls with authority from the moment you touch the throttle. The combination of the cam, head work, and transformed this into an absolute monster.

This 14 Jeep SRT8 didn't just show up for a supercharger and hope for the best.
The owner did what many people skip—he built the foundation first.

✅ Camshaft
✅ Ported Heads




The result?

A brutally responsive, hard-charging that pulls with authority from the moment you touch the throttle. The combination of the cam, head work, and boost transformed this into an absolute monster.

06/12/2026

This 2014 Jeep
came in for Custom Tuning after a fresh engine build.
After getting some mechanical issues sorted out, we put together a Custom tune and a Stage 3
tune.

The result?

The cam chop is ridiculous.
The shifts are harder.
Crisp throttle response.
Improved drivability.
