Ordering and production

Estimated lead time: 8–10 weeks before shipment. This includes Circle D's current production estimate plus additional time for specification review, order surges and the third-party handoff. It is an estimate, not a guaranteed delivery date.

SMGspeed may contact you after checkout to confirm the vehicle, transmission, engine combination, power level, power adder, intended use and requested stall before submitting the build.

Core notice: Some factory-core applications require a usable customer core. Any selection labeled CORE REQUIRED is priced with that requirement. Core freight, missing cores or unusable cores may create additional charges. SMGspeed will confirm any core requirement before production.

Custom made-to-order item: Review all selections carefully. Changes or cancellation may not be possible after production begins.
