Hey engine builders and detailers, sometimes it's the small stuff that makes a difference. This Trans-Dapt 9812 is a simple chrome valve cover bolt designed for centerbolt-style valve covers (the kind where the bolts go straight down through the middle of the cover, common on many Chevy small blocks and other engines). It's made to work with all Trans-Dapt valve covers, and they have versions for both short and tall covers. While it's a functional part that secures your valve cover, the real purpose here is aesthetics. It replaces that plain, rusty, or painted factory bolt with a shiny chrome piece that adds a nice finishing touch to a clean engine bay. It's a cheap and easy way to add a bit of bling under the hood. Just make sure your valve covers use this centerbolt style before ordering. A pack of these can really tie together the look of your polished or chromed valve covers.
