ABOUT US ENGINE
Over 45 years of experience in the remanufactured engine industry, with a dedicated division for Hummer H1 and HMMWV parts, engines, and upgrades.
OUR STORY
US Engine Production has been a trusted name in the remanufactured engine industry for over 45 years. Based in Lindenhurst, New York, we have built our reputation on quality workmanship, honest pricing, and deep expertise in diesel and gas engines.
Our Hummer H1 & HMMWV Division was born from a passion for these iconic vehicles. We recognized that Hummer H1 and Government Surplus Humvee owners needed a dedicated source for quality parts, engines, and upgrades — not a generic auto parts store that carries a few items as an afterthought.
Today, we stock over 3,900 parts in our catalog, with most items available for immediate shipment from our NY warehouse. Whether you need a complete 6.5L turbo diesel long block, a simple glow plug set, or a full performance upgrade package, we have you covered.
We do NOT carry H2 or H3 parts. ONLY the real deal — Hummer H1 and HMMWV.
