    Supreme Power sells both replacement and competition use only performance parts. Competition use only parts may only be used according to the guidelines listed below.

    California regulates automobile aftermarket parts that have the potential to impact emissions. In most cases, the sale and use of emissions related aftermarket parts on automobiles is prohibited unless it is either a “replacement part” as defined by California or is a specifically authorized use of that part as reflected in an Executive Order, an EO Part.

    All items purchased from Supreme Power be shipped via UPS Ground unless prohibited by size or weight, in which case a motor freight carrier will be utilized.

    Expedited shipping may be available at an additional cost upon request. If you have shipping deadlines that need to be met, please speak with a staff member before placing your order.

    For international orders, we may elect to ship by TNT at our discretion. Please note that Trade agreements vary between Canada and foreign countries.

    For this reason, brokerage fees, duties, and taxes applicable to the importation of any items purchased from Supreme Power are the full responsibility of the customer.

    Thank you for choosing Supreme Power.
