A billet crankshaft is a high-performance engine component made from solid steel or aluminum alloy, machined from a single piece of material. This construction method provides superior strength and durability compared to cast crankshafts, allowing for higher power outputs and improved engine efficiency. Billet crankshafts are typically used in high-performance racing applications and custom engine builds where reliability and performance are critical.
| Material | Steel or aluminum alloy |
| Manufacturing process | CNC machining from solid billet |
| Weight | Varies by application, typically 20 to 50 lbs |
| Stroke length | Customizable, typically 2.5 to 4.5 inches |
| Main journal size | Common sizes range from 2.0 to 2.5 inches |
| RPM rating | Designed for high RPM applications, up to 10,000 RPM |
When selecting a billet crankshaft, buyers should consider the specific engine application and performance goals. Important specifications include the desired stroke length, main journal size, and material choice. Additionally, inquire about any necessary tolerances and certifications based on the intended use, especially for racing applications. Quantities may vary based on whether the buyer is looking for a single unit or multiple units for production.
