BETTER THAN NEW

Machine Shop Services You Can Rely On

At Arizona Engine Rebuilding , we specialize in high-quality engine restoration and machining services that bring worn or damaged engines back to life. Whether you’re a professional mechanic, restoration enthusiast, or someone looking to get more life out of your vehicle, our full-service in-house machine shop is equipped with the tools, talent, and technology needed to restore your engine components to peak operating condition.

Precision Machining for Lasting Engine Performance

Every successful engine rebuild starts with precise measurements and expert machining. Our experienced technicians use advanced equipment to diagnose, measure, and restore your engine parts so they meet or exceed factory specifications. From light-duty vehicles to performance builds and diesel engines, we tailor our services to match the specific needs of your project.

Our machine shop isn’t just a service add-on—it’s the heart of what we do. Unlike many rebuilders who outsource machine work, we handle all processes in-house. This gives us full control over the quality, turnaround time, and performance of every engine we rebuild.

Comprehensive Engine Machine Shop Capabilities

In addition to our core services, we offer a full spectrum of machining and rebuilding options, including:

  • Connecting rod resizing and balancing
  • Camshaft bearing installation
  • Thread repair and helicoil installation
  • Pressure testing and hot tank cleaning
  • Custom engine builds and balancing for performance applications

From complete engine overhauls to individual component repairs, we tailor our services to your engine’s specific needs and your performance goals.

Crankshaft Services

Your crankshaft is one of the most important rotating components in your engine. Over time, wear and damage can throw off the balance, reduce performance, or even cause engine failure. Our crankshaft services include:

  • Crankshaft grinding and polishing
  • Journals inspected and machined to proper tolerances
  • Crankshaft balancing for reduced vibration and improved longevity

We inspect each crankshaft for cracks, wear, and alignment issues using industry-standard tools and techniques, ensuring that it meets exact tolerances before it goes back into your engine.

Block Milling

Proper block milling is essential for achieving the flat surfaces needed to ensure a tight seal between the engine block and cylinder head. Any warping or imperfections in the block can lead to gasket failures, compression leaks, and engine inefficiencies. Our technicians use precision milling equipment to restore these surfaces to manufacturer specs. Whether you're dealing with heat damage, corrosion, or general wear, we’ll return your engine block to a smooth, level condition that supports maximum engine efficiency.

Valve Jobs

Valve work is a critical part of the engine rebuilding process. Worn or improperly seated valves can lead to loss of compression, poor fuel economy, and decreased performance. Our complete valve job services include:

  • Valve grinding and lapping
  • Seat cutting and installation
  • Valve guide replacement or resizing
  • Inspection for cracks and wear

By ensuring that valves seat perfectly and seal tightly, we help your engine breathe better, burn fuel more efficiently, and produce more power.

Cylinder Boring and Honing 

When cylinders are worn or damaged, simple cleaning isn’t enough. We offer professional boring and honing services to restore cylinder walls to the proper diameter and finish. This includes:

  • Overbore sizing for oversized pistons
  • Plateau honing for improved oil retention
  • Crosshatch patterns optimized for piston ring seating

Precision boring and honing are essential for proper compression and ring seal, helping your rebuilt engine run smoother and last longer.

In-House Quality Control and Tight Tolerances

What sets Arizona Engine Rebuilding apart is our commitment to detail. Every component we touch is checked and double-checked for dimensional accuracy. Whether it’s a journal diameter, bore taper, or deck surface, we machine every part to strict tolerances that support high-performance rebuilds and long-term reliability.

We don’t cut corners—and that’s why mechanics, car enthusiasts, and fleet owners across Arizona trust us to deliver superior machining work every time.
