Speed Engineering LS Swap Headers - 1-7/8" Full Length

WILL NOT SHIP TO CALIFORNIA

Speed Engineering headers are made out of 304 stainless steel and offer great quality, performance, and affordability. These headers are mandrel bent, tig welded, and feature natural (raw, unpolished) stainless steel construction. All of our headers have been dyno proven. We stand behind our headers in saying you will not find a better fitting, quality built, budget header for your vehicle.

Features include:

  • Mandrel Bent Tubing
  • 1 7/8" Primaries
  • 3" Collector
  • V8 Engines Only
  • Merge Spike
  • 4.8L, 5.3L, 6.0L, 6.2L Engines
  • CNC Machined Flanges
  • Natural 304 Stainless Steel
  • Standard Graphite Manifold Gaskets

Vehicles:

  • 1960+ C10 Trucks
  • 1988-1998 C1500 Trucks (Silverado, Sierra) Motor Mounts 1" offset back or further required to clear. Most mounts don't offer that and would recommend the mid lengths for ease of installation. These long tubes may requiring "denting" in the tubes to fit and/or extensive modifications.
  • (1960-1966 C10 Trucks require slider engine mounts to clear the front crossmember)

Note: "Due to older vehicle frame clearance headers are pulled in very tight, and require our spark plug wires".

Note: "For LS series engine swaps only" These do not work on standard SBC or BBC engines.

Note: If using a larger 4L80E or older Turbo 350/400 transmission the bellhousing ears may need to be trimmed for proper clearance.

Note: "Does not fit 4wd"

headers

Bought the headers for my ls swapped 70 c10 and they are the best fitting headers i have ever gotten in the last 28 years. Still got a long way to go till it runs but they fit and look great.
