About Us

1PZ is the official online store for 1PZ replacement parts.

Founded in 2000 and based in California, 1PZ supplies aftermarket parts for ATVs, go-karts, dirt bikes, pocket bikes, scooters, motorcycles, and small engines.

Our goal is to make replacement-part shopping clearer. Product pages include compatibility details, dimensions, reference numbers, and installation notes where available. Always compare those details with your vehicle or engine before ordering.

Orders ship from California, USA. Standard delivery is typically 3–5 business days after processing.

Contact 1PZ support if you need help checking fitment before purchase. You can also review our shipping policy, return and refund policy, and privacy policy.
