LS Swap 1-3/4" Primary Headers - Mid Length

WILL NOT SHIP TO CALIFORNIA

Pro Performance is proud to bring another winner to the classic truck table! These mid-length LS headers are built with 304 stainless steel for good looks and a long life, even in harsher climates. With 1 3/4" mandrel bent primary tubes and stepped, 3" V-band collectors, these headers perform as well as they look!

Intelligently designed for all GM LS engines with CNC-machined, 3/8" thick flanges, and the primary tube routing keeps things tucked in nicely to fit a variety of chassis designs.

Features:

• 1 3/4" Primaries
• 3" Collectors
• Mandrel Bent Tubing
• V-Band Collectors
• Collector Extensions with O2 Sensor Bungs
• Port Matched & CNC Machined Flanges
• Polished 304 Stainless Steel
• Graphite Manifold Gaskets Included
  

Note: Angle-boot plug wires are strongly recommended with these headers. Measure your length from the coil to the plug, and order them here.

Note: If using a 4L80E or Turbo 350/400 transmission, the bellhousing ears may need to be trimmed for header clearance. These headers are tucked in tight to fit into narrow chassis.

Tested Vehicle Applications:

• 1960-87 Chevy/GMC C10 trucks and SUV
