Order this service through SMG
This listing covers service work on a customer-supplied component. Place the order through SMG Speed and wait for the order-specific authorization and shipping instructions before sending any parts. SMG’s instructions supersede any manufacturer-direct checkout, email, or ship-to language retained above for technical reference.
Service shipping and timing
The customer is responsible for securely shipping the clean, drained, and correctly prepared component to the service location. Remove loose sensors, fittings, and gaskets unless SMG instructs otherwise; do not use loose packing peanuts. Advertised shop turnaround begins after the correct component is received and inspected, and does not include transit time, cleaning, repairs, or additional disassembly. Return shipping is calculated at checkout when the service requires the component to be shipped back.
Performance and compatibility
Power gains and results depend on the complete engine, pulley ratio, airflow, cooling, fuel system, calibration, and operating conditions. Verify the exact supercharger model and required supporting components before ordering; stated gains are not guaranteed.
Processing & Shipping Overview
Processing occurs before shipping.
Most in-stock items typically process within 2–3 business days before shipment or pickup. Expedited shipping options affect transit time after an order ships and do not speed up processing.
Made-to-order, special-order, vendor drop-ship, and freight items require additional processing time before shipping. Any extended lead times will be noted on the product page when applicable.
For the most up-to-date order status or lead time questions, please contact sales@smgspeed.com or use live chat during business hours.
