Overview:

Holley's new GM Muscle Series accessories are the latest expansion to our officially licensed GM product line. These die-cast aluminum valve covers and air cleaner kits were designed to have a no-frills, modern style with prominent raised GM "Chevrolet and Bowtie" logos. Intended as an alternative to the existing GM ZZ6 accessories, Holley's GM Muscle Series dress up accessories can be the perfect addition to your engine bay if you are searching for a subtly custom variation from the OEM options. All GM Muscle Series accessories are available in four custom finishes: natural cast, polished, satin black, and factory orange (all finishes have machined "Chevrolet and Bowtie" logos aside from polished version). The Small Block Chevy center bolt valve covers (designed to fit Vortec/ZZ4/ZZ5/ZZ6) feature a generous internal height for exceptional valve train clearance and include pre-installed internal baffling, polished mounting hardware, and oil fill / PCV grommets (valve cover gaskets not included).

Features:

  • Features clean, modern styling with high definition “Chevrolet and Bowtie” logo
  • Specifically designed for GM ZZ6 engines, but will fit all Small Block Chevy applications with center bolt style cylinder heads (Vortec, ZZ4, ZZ5, ZZ6) – polished mounting hardware included
  • Die-cast aluminum construction ensures high detail and reduces the opportunity for warping of the valve cover flange and oil leaks
  • Emissions compliant valve covers include pre-installed internal oil baffles as well as an oil fill plug and PCV grommet
  • Offered in four unique finishes to fit your style: natural cast aluminum with machined logo (ready for custom paint), polished, satin black with machined logo, and factory orange with machined logo

Great Socks.
Color: (002) Black / Black / Halo Gray, Size: Large
These are awesome and have become my favorite socks to have for everyday wear. I have since bought the hightop version as well and there are just as equally great. They fit almost like compression socks. Color does fade a bit after repeated washing but not enough to make a big difference in appearance. They have lasted for a long time and still going. They have lots of cushion which makes it very comfortable to wear.

Great Socks
Color: (001) Black / Black / Castlerock, Size: Large
I keep ordering these over and over again. They fit well, and are soft and comfortable. My feet don't sweat like crazy while wearing them. The cupped heel makes them fit even better. They hold up to everything from everyday use to active lifestyles.

Good sock but thick
Color: (001) Black / Black / Castlerock, Size: Small
These Under Armour socks are high quality and definitely durable, with great cushioning and a solid fit that stays in place throughout the day. The material feels supportive and they hold up well after multiple washes without losing shape. My only minor downside is that they’re thicker than I expected. They feel more like a heavy-duty training sock, which is great for colder weather or intense workouts, but a bit bulky for everyday sneakers or warmer days. That said, the quality is excellent, and if you prefer a thicker, more cushioned sock, these are perfect. Just something to be aware of depending on how you plan to use them.
