Premium Diesel Glow Plugs

Made in the USA

Chevy / GMC LB7 2001 - 2004 Duramax glow plugs

Note: These glow plugs will fit all 2001 - 2004.5 Duramax trucks. If you have a 2004 Duramax you will need to verify if it is an LB7 or LLY. If the eighth digit of the VIN is a "1" then you have an LB7 and these plugs will fit. They will NOT fit 2004.5 and later Duramax. . If you need the later plug please see 'related items' below.

  • Our Chevy / GMC LB7 glow plugs are the only ones manufactured in the USA - any other brand you purchase is made in another country - support American workers!
  • OEM Quality - Mention any major player in commercial diesel engines, and our manufacturer has probably made their glow plugs. In fact our glow plugs come out of the very same factory that exclusively manufacturers glow plugs for the US Military HUMVEE.
  • Quality control - Our 2001 - 2004 Duramax glow plugs are made in an ISO 9001:2000 certified facility. Every glow plug undergoes stringent examination and testing before being shipped. In fact, every glow plug is tested twice before delivery. The defective rate last year was a mere 0.00007 percent!
  • Post heating - Our glow plugs are designed to continue delivering heat for a short period after power is removed - this contributes to smoother engine operations with less smoke
  • Long life - Premium glow plugs are designed for longevity, and also to resist the swelling problem common with many poorly designed glow plugs that makes removal difficult or impossible.
