PLEASE NOTE: Scouting America (formerly Boy Scouts of America, or BSA) has updated the Pinewood Derby wheel molds. These new wheels began production in late 2025 and started appearing in kits in Spring 2026. The previous wheels (first produced in 2009) are still in circulation. We are offering both the new (2025) and older (2009) wheels. The main difference is the lettering on the outside of the wheel: the new wheels have “OFFICIAL” on the sidewall instead of “BSA,” which appears on the 2009 version. The new wheels have excellent spin characteristics, but are a bit heavier (approximately 0.35g more) than the old wheels. If you purchase modified wheels, we recommend using the old (2009) wheels unless your rules require wheels from the current year or a current kit, because of this weight difference.
