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

Cord is not durable. Not for unsupervised play.
Size: Medium, Style: Ultra Duo Tug
My dog loves this toy and chewed through the tether in about 15 minutes, making it pretty useless as a tug toy. So the cord is not durable as stated. This is not for dogs who love to chew. Also, it is a bit smaller, much more squishy and chewable than a tennis ball, and I was worried she would chew it apart and that it might get stuck in her throat without the tether, so I took it away, much to her disappointment.

Puppy's favourite, but not built to last.
My puppy absolutely adores this tug-of-war ball! However, I have to mention the durability—it started fraying after just a few days of use. While it’s still usable, the material doesn’t hold up well to enthusiastic chewing and tugging. If your pup is a strong chewer, this might not last long. That said, for the price and the joy it brings my puppy, I’d still consider buying it again—just with the expectation that it’s more of a short-term toy. Great for light play, but not built for heavy-duty tug sessions.
