Speed Engineering Universal LT 1 3/4" Turbo Headers - Forward/Upward Facing
Speed Engineering 25-1055 polished stainless-steel LT turbo headers feature 1 3/4-inch primaries, short collectors, 3-inch V-band outlets and a built-in 44mm wastegate mounting location. Designed for LT1/LT4 swaps and custom forward-facing turbo fabrication.
Includes manufacturer-supplied graphite gaskets and installation hardware.
SMG recommended upgrades: Choose our vehicle-correct SMG LT MLS gasket set and/or 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.
Speed Engineering has tested fitment on 2014-2019 Chevrolet Silverado and GMC Sierra LT-engine trucks. Other applications may require A/C, brake, or fabrication changes.
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.
