RockAuto tracking FAQ

Why did my RockAuto order split into Warehouse A and Warehouse B with different carriers?
RockAuto connects directly to hundreds of wholesale auto parts distributors nationwide. Choosing parts from two different warehouse letters dispatches two separate boxes—often one via FedEx or UPS and another via USPS.
How does RockAuto ship to Canada without brokerage surprise fees?
When GST/HST is prepaid at RockAuto checkout, FedEx, DHL Express, Purolator, and Canada Post clear CBSA customs automatically without charging doorstep COD brokerage fees.
How are heavy brake rotors, control arms, and exhaust pipes shipped by RockAuto?
Heavy cast-iron brake rotors and suspension assemblies ship via FedEx Ground or UPS Ground in reinforced double-walled cartons.
