Terms of Use

Bullet LSX Engines LLC · Glendale, Arizona · Last updated November 3, 2026

These terms cover your use of the Bullet LSX Engines engine builder at parts.bulletlsx.com and the related pages, quotes, spec sheets and build packets (together, the "Builder"). By using the Builder you agree to these terms.

1. Ownership

The Builder — including its software, page design, parts-fitment rules, compatibility logic, power estimates, recommendations, spec sheets, build instructions, torque packets, parts data, descriptions and original photos — is owned by Bullet LSX Engines LLC and protected by copyright and other laws. All rights are reserved. Product names, part numbers and brand names belong to their respective owners and are used only to identify the parts we sell.

2. What you may do

You may use the Builder to plan an engine, request a quote, buy parts or a build from us, and print or save your own spec sheet and build packet for your build and your machine shop.

3. What you may not do

• Copy, download, scrape, mirror, frame or republish the Builder or its data, in whole or in part, for any commercial purpose.
• Reverse engineer, decompile or extract the Builder's code, rules or data, or use them to build, train or improve a competing configurator, catalog or service.
• Use bots, scripts or automated tools to access the Builder, other than ordinary search-engine indexing.
• Remove or alter copyright or ownership notices.

Dealers, distributors and other businesses interested in using the Builder can contact us about a license.

4. Estimates and fitment

Horsepower figures, compression ratios and other numbers are estimates. Fitment guidance is based on manufacturer data and our experience but can't account for every variation in used or modified engines. Your machine shop must verify all clearances, dimensions and specifications before assembly. Final pricing, availability and fitment are confirmed at order or teardown.

5. Orders

Payments are processed by Stripe. Parts ship from our suppliers. Special-order and custom parts (for example custom pistons and cut cams) are non-returnable. Freight on blocks and cores is quoted separately.

6. Limitation of liability

The Builder is provided "as is." To the extent allowed by law, Bullet LSX Engines LLC is not liable for indirect or consequential damages arising from use of the Builder or from engine assembly performed by others.

7. Changes

We may update these terms. Continued use of the Builder after an update means you accept the new terms. These terms are governed by the laws of the State of Arizona.
