Built by Builders, for Builders

Billet Speed was born out of a simple frustration: performance parts that looked the part but didn't fit right, didn't hold up, or weren't made by people who actually turn wrenches. We set out to fix that.

We design and manufacture high-performance LS alternator brackets, fuel injector holders, and billet engine accessories right here in the USA. Every part is CNC machined from billet aluminum — not cast, not stamped, not sourced overseas. That means tighter tolerances, cleaner finishes, and fitment you can count on the first time.

Why Billet Aluminum? Why CNC?

Billet aluminum starts as a solid block of material. When we machine a bracket or holder from billet, we're cutting away everything that doesn't belong — leaving behind a part with consistent grain structure, superior strength-to-weight ratio, and dimensional accuracy that cast parts simply can't match.

CNC machining means every part comes off the machine to the same spec, every time. No hand-fitting. No guessing. If it's a Billet Speed part, it fits the way it's supposed to.

Made in the USA — and That Matters

We machine our parts domestically because it gives us direct control over quality at every step. We're not waiting on overseas shipments or hoping a supplier hit spec. We know exactly what goes into every part because we make it ourselves.

For racers and builders putting serious power through their engines, that accountability isn't a marketing line — it's the whole point.

Who We Build For

Our customers are engine builders, weekend racers, pro shop fabricators, and enthusiasts who've been burned by cheap hardware before. They know the difference between a part that looks good in a photo and one that actually performs under heat, vibration, and load. We build for them.

If you're swapping an LS, building a dedicated race car, or just refuse to put junk under your hood — you're in the right place.
