• What is the snell helmet expiration date?

  adminApr 22, 2026

  • As a general rule, Snell SA helmets are valid for 10 years from their certification date. For example, a Snell SA2025 helmet is good until December 31, 2035. When a new certification comes out, such as SA2030, those helmets are valid until December 31, 2040. Most racing organizations like SCCA, NASA, and NHRA follow this guideline. However, we always recommend checking your specific rulebook, as requirements may vary between different organizations or events.
