Hemi VVT Crankshaft Gear Spacer CPP-0550 By Callies

Is your harmonic balancer sitting awkwardly like a bad first date? Not anymore. The Callies CPP-0550 Harmonic Balancer Spacer is here to make sure your HEMI’s rotating assembly fits together like peanut butter and horsepower.

Designed specifically for Chrysler HEMI engines (yeah, we’re talkin’ 5.7L, 6.1L, 6.2L, 6.4L—you name it), this high-quality spacer ensures your harmonic balancer and pulley line up just right. Because when you’re chasing big RPMs or building your dream engine, millimeters matter. Don’t let misalignment ruin your vibe—or your crankshaft.

Precision-machined from quality material and designed to last longer than your last relationship, this spacer gives your setup the support it needs without complicating your build. It installs easily (no PhD required), plays nice with aftermarket parts, and won’t throw a tantrum when things get hot under the hood.

This isn’t one of those universal “kinda fits, kinda doesn’t” spacers. Nope. Callies made it for HEMIs, by people who actually wrench on HEMIs. It’s as plug-and-play as it gets, but still gives your engine bay that “yeah, I know what I’m doing” look.

So, if your balancer is begging for some breathing room, do it a favor—add this spacer and keep things smooth, steady, and downright HEMI-happy. Your timing components will thank you. And hey, at this price? It’s basically the engine part equivalent of finding twenty bucks in your jacket.
