Premium Remanufactured Hummer Engines – Dyno Tested, Certified & Warrantied

Remanufactured Hummer Engines You Can Rely On

When your Hummer’s powerhouse starts showing signs of wear, replacing the entire SUV isn’t your only option. A remanufactured Hummer engine gives you factory-grade performance and durability—without the cost of a brand-new motor.

Our remanufactured engines are fully rebuilt, tested to OEM standards, and backed by industry-leading warranties, ensuring your Hummer keeps its rugged reliability and off-road strength for years to come.

Whether you own a Hummer H1, H2, or H3, or a GM-based commercial variant, a remanufactured engine restores power, towing capacity, and confidence both on and off the road.

What Makes a Remanufactured Hummer Engine Different?

A remanufactured engine is far more than a repair—it’s a complete engineering rebuild designed to meet original factory specifications.

Each Hummer engine is disassembled, cleaned, precision-machined, and reassembled with new or reconditioned components that meet strict OEM tolerances.

Key components replaced or rebuilt include:

• Pistons & Rings
• Crankshaft
• Camshaft
• Cylinder Heads
• Valvetrain Components
• Bearings
• Gaskets & Seals
• Timing Components
• Oil Pump

Every finished engine undergoes pressure, compression, and dyno testing to confirm it performs equal to—or better than—a new factory unit.

Why Choose Remanufactured Over Used or Rebuilt?

A remanufactured Hummer engine provides the same power, torque, and reliability as a brand-new OEM motor at nearly half the price—ideal for both off-road enthusiasts and professional repair shops.

Warranty & Certification You Can Trust

Each remanufactured Hummer engine is backed by industry-leading warranties ranging from 12 months to 5 years, depending on model and usage.

Certifications and Quality Assurance include:

• ISO Certified Remanufacturing Facilities
• AERA Automotive Machining Standards
• OEM-Grade Components and Assembly
• Compression, Leak, and Dyno Testing Documentation

You’ll receive full documentation verifying your engine’s testing results and warranty details with every purchase.
