Keep your LB7 running leak-free and looking clean with the Merchant Automotive Lower Valve Cover Grommet for 2001–2004 GM 6.6L Duramax LB7, these grommets are available individually or as a complete set.
Designed to seal up the lower valve cover bolts, these grommets help prevent oil seepage and ensure a tight fit that holds up under heat and pressure. Over time, the factory rubber can dry out and crack, leading to pesky leaks. Swapping them out with fresh, quality replacements from Merchant Automotive keeps your engine leak free.
When you're chasing down a leak or doing a full top-end refresh, grab a single grommet or a full set and get the job done right the first time.

Pretty Colors to Encourage Me to Walk!
Size: X-Large, Color: (601) Bittersweet Pink / Stone / Stone
Hum. Extra large does not seem extra large. I have a slender but size 10-10.5 foot. Will keep but was hoping for a looser fit. Bought to match an Under Armour walking outfit.

Very nice
Size: Large, Color: (100) White / White / Pitch Gray
I just received these for my son. They are very nice and look sturdy, but he hasn't worn them yet, so I cannot speak to how well they hold up in the wash or when worn. They appear to be the right size and look stretchy, but not the kind of stretchy that feels super tight on the foot (which I don't like). If they wear unusually well or poorly, I will come back and edit this.

I bought these originally at my local UA store and had to buy more. They are my favorite daily wear.
