Gen3 HEMI Billet Aluminum Valve Covers by MMX

Let’s face it—stock valve covers are about as exciting as soggy toast. So if your HEMI’s rocking the same tired look from 2003, it’s time for an upgrade that actually looks as good as it performs.

Say hello to our Billet Aluminum Valve Covers, made just for the 5.7L, 6.1L, and 6.4L HEMI crowd (that’s 2003 through 2024 if you’re counting). These aren’t just chunks of aluminum pretending to be cool—they’re precision-machined beauties built to handle real horsepower and real heat, without flexing under pressure like your cousin trying to bench 225.

Crafted from solid billet aluminum, they bring the bling and the brawn. Want to run breathers? We’ve got your back. We offer optional 3-axis CNC machining to get you set up for valve cover breathers—so your engine can catch its breath after screaming down the quarter mile or just sitting in traffic pretending it’s a lion in a cage.

Whether you’re building a showpiece, a track monster, or just want your engine bay to stop looking like a beige office cubicle, these covers do the job with style and strength.

Install ‘em. Admire ‘em. Rev ‘em. And yeah, maybe show ‘em off a little more than necessary—we won’t judge.
