DmaxStore Billet Fuel Cap, 2001-2026 LB7/LLY/LBZ/LMM/LML/L5P

Best fuel tank cap I have ever seen…Thank goodness for the DMAX Store…Bravo…p.s. I love my Duramax diesel truck…I’m glad a store is dedicated to providing parts to keep it running…BRAVO again…

Great replacement over factory and plastic , looks amazing

This is a fantastic gas cap. It fits and tightens better than the OEM cap. Although I like the magnet, I’m not the fondest of using it,the only place I can use it is on the painted surface of my truck, and I don’t want to scratch it up. The fuel door is plastic on the inside, but the cap hangs just fine on the fuel door hook and I use the leash that came with it which is unobtrusive and doesn’t get in the way or stick and twist.
