Speed Engineering LT Swap 1 7/8" Longtube Headers - G-Body & 2WD OBS C1500
Speed Engineering stainless-steel LT swap headers. Includes the manufacturer-supplied graphite header gaskets and installation hardware.
SMG recommended upgrades: Choose our vehicle-correct SMG MLS gasket set for a durable seal, and add SMG 9070C Ceramic Plug Wires. The ceramic boots resist header heat and melting; these are the only plug wires we use on our in-house header builds.
SKU: 25-1165. Speed Engineering uses this same 1 7/8-inch LT swap header SKU for 1982-1988 GM G-body and 1988-1998 2WD OBS Silverado/Sierra C1500 applications. Verify mounts, steering and transmission clearance for your build.
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.
