Do you offer parts for all Hummer models and years?

Yes — complete coverage for the H1 (1992–2006), H2 and H2 SUT (2003–2009), H3 and H3T (2006–2010), including Alpha, X, and Adventure packages, plus components for the 2022+ GMC Hummer EV Pickup and SUV.

Where can I get Hummer parts now that the brand is discontinued?

Right here — Hummer ended production in 2010, so no dealership stocks new H1, H2, or H3 parts. Our documented donor network is built for exactly this situation: genuine OEM components for a brand the dealers left behind.

What Hummer engines do you stock?

Tested 6.6L Duramax diesels for the H1 Alpha, 6.0L and 6.2L Vortec V8s for the H2, 5.3L V8s and five-cylinders for the H3 — plus Ultium drive units for the Hummer EV. Every engine is compression-tested and warrantied 60–90 days.

Are H1 parts really military-grade?

The H1 shares its lineage with the military HMMWV, so many components genuinely are military-derived. The H2 and H3 are civilian GM-platform trucks — we describe every part accurately so you know exactly what you're buying.

Why should I order Hummer parts by VIN?

Because packages change everything: an H3 Alpha carries a V8 where base H3s have a five-cylinder, and Adventure packages use different gearing. The 17-character VIN code determines precisely which model is produced, ensuring that incorrect parts won't be returned.

What if I need help locating the right part?

Simply call toll-free at 1-800-606-1107, and our US-based experts will decode the VIN for you and determine fitment. If the part is out of stock, we'll locate it from our nation-wide donor car network.

Here's what every Hummer owner knows: the brand ended production in 2010, and no dealership has stocked new H1, H2, or H3 parts in over a decade. The used market isn't the budget option for these trucks — it's the only option, and we've built one of the deepest Hummer inventories in the country. From the military-derived H1 through the final H3s, plus components for the 2022+ GMC Hummer EV revival.

Generations Guide

Hummer Generations: Complete Guide

From military origins to electric future — understand the differences between each Hummer generation to find the right parts for your vehicle.

H1

1992–2006

The closest thing to a military 'Humvee' you can buy. It is wide, utilitarian, and built on a heavy-duty chassis. It shares many components directly with military surplus, making it a 'mechanic's special' that requires very specific, often military-spec, parts.

Military-GradeDieselHeavy-Duty⚡ Military-Spec

H2

2002–2009

The 'Civilian' icon. Built on a modified GM truck platform (the GMT820), it moved away from the military chassis to provide a more luxurious, daily-driver experience. It is the most common platform you will see in used parts inventories.

GMT820LuxuryDaily Driver

H3

2005–2010

The mid-sized off-roader. Built on the smaller GMT355 platform (shared with the Chevy Colorado), it was designed to be more fuel-efficient and accessible. If you are shopping for H3 parts, you must be careful: the 'Alpha' trim uses a completely different V8 powertrain compared to the standard inline-5 engines.

GMC Hummer EV

2022–Present

A complete departure. This is a high-tech electric vehicle built on GM's Ultium platform. It shares virtually no mechanical or electronic DNA with the previous gas/diesel models.
