Which Performance Part Categories Can I Shop on Lethal Performance?

Lethal Performance sells Ford and Mustang performance parts across six main categories: exhaust, air intakes, wheels, superchargers, tuning, and suspension. You can browse these as a general catalog or narrow by vehicle—Mustang, F-150, Bronco, GT500, and others. The site also has an Upgrade Kits and Parts collection for bundled builds. Free shipping applies to most orders over $199, though oversized items are excluded.

The Six Core Categories

The homepage lists these as "Popular Categories," and they map directly to the most common build stages:

If you already know your goal—sound, power, or handling—start with the matching category rather than scrolling the full catalog.

Browsing by Vehicle

The catalog is organized around Ford platforms, so you can filter to your model instead of sorting through universal parts. The site names Mustang, F-150, Bronco, and GT500 as supported vehicles. This matters because fitment differs sharply across platforms—a Mustang exhaust won't cross over to an F-150, and Bronco suspension is its own world.

Practical approach: pick your vehicle first, then the category. That order avoids dead ends where a part looks right but doesn't fit.

Upgrade Kits and Bundles

Beyond single parts, there's an Upgrade Kits and Parts collection. These bundle components that are meant to work together—useful if you'd rather not piece together a build from scratch. The tradeoff is less flexibility: a kit commits you to a preset combination, while individual parts let you mix brands and stages.

Choose a kit if you want a proven combination and fewer compatibility questions. Choose individual parts if you're building incrementally or have specific brand preferences.

What the Site Says About Its Own Builds

Lethal Performance states it has built, dyno-tested, and raced the same parts it sells for more than 20 years. It cites a 2024 Mustang Dark Horse running 8.87 seconds at 154 mph and 1,049 rear-wheel horsepower on a Whipple supercharger, with factory headers and full interior. It also references a 2024 Mustang GT at 830+ rwhp through a manual MT82 and a 2026 Bronco on 35s with forged wheels.

These are the company's own claims about its builds, not independent test results. They're useful as a signal of what combinations the shop has actually assembled, but treat the numbers as marketing until you verify with your own tuner or shop.

Payment and Protection at Checkout

Two options appear at checkout that affect total cost:

• Affirm financing — split a build into monthly payments; the site says checking takes about a minute and won't affect your credit score.
• Shop Pay — for smaller orders.
• Route package protection — covers lost, stolen, or damaged packages; every order is eligible.
• Extend warranties — added at checkout to cover parts after installation.

None of these change which categories you can shop, but they change what you pay upfront versus over time. Confirm the terms on the checkout page before committing.

A Sensible Starting Point

If you're unsure where to begin, the site points to the S650 Mustang GT as a highly buildable platform and offers a complete guide covering part order—exhaust before headers, tune before or after intake, and whether a supercharger makes sense before fuel system work. That guide is the better entry point than the category list if your question is "what first" rather than "what exists."

For everyone else: choose your vehicle, pick the category matching your goal, and check fitment before checkout.
