Speed Engineering LS Truck-Series 1 3/4" Forward-Facing Turbo Headers
Speed Engineering 25-1036 truck-series GM LS 1 3/4-inch forward-facing/upward turbo headers. Mandrel-bent, TIG-welded natural 304 stainless construction with short 3-inch collectors, CNC-machined flanges and included graphite gaskets. Designed around truck accessories and tested in 1999-2013 GM trucks/SUVs, 1988-1998 C1500 LS swaps and 1967-1987 C10 LS swaps.
Choose SMG LS MLS gaskets, SMG 9070C ceramic plug wires, or both. The heat-resistant ceramic boots will not melt against header tubes like conventional boots can, and 9070C is the only wire set SMG uses on in-house header builds. Custom turbo fabrication and vehicle-specific A/C, brake and clearance work may be required. Race-use product.
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.
