Fitment
For the 2004–2007 Classic-body GM 2500 6.0L application. The 2007 listing applies to the Classic body, not the new-body truck. Confirm model year, engine, body style, accessory arrangement, and intended boost before ordering. This listing does not cover diesel or 8.1L engines.
Tuner kit requirements
Fuel-system components and tuning are not included. Supporting fuel upgrades and a suitable custom tune must be selected for the vehicle and power target. Tuner kits are not emissions certified; verify requirements for the intended use.
Vehicle details for kit selection
Provide the model year, exact truck model, 2WD or 4WD configuration, and whether the truck has hydroboost brakes, along with the VIN and 6.0L engine confirmation. These details help confirm the correct installation configuration before fulfillment.
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.
