Note: Headers do not hang below TRUCK frame and offer ground clearance with air ride suspension and lowered suspension. Customers have installed this product on Choppin Block, Roadster Shop(with Pro spindles), Porterbuilt, and other front drop members with air ride and coil over suspension.
Note: Due to older vehicle frame clearance, headers are pulled in very tight and require Speed Engineering plug wires
Note: If using a larger 4L80E, older Turbo 350/400 or Manual transmission the bellhousing ears may need to be trimmed for proper clearance
Note: Can fit 4wd C10 K10 applications with proper engine position and custom exhaust work. Having lifted suspension is a plus for driveline clearance.
