Reliable Power for Classic GM Trucks

Upgrade your 1967-1991 GM fullsize truck or SUV with these Hedman Hedders Street series headers. Designed specifically for small block Chevy engines, these headers offer a cost-effective way to improve engine breathing and overall performance without sacrificing durability.

Performance Specifications

  • Primary Tube Diameter: 1.625 inches
  • Collector Diameter: 3 inches
  • Material: Heavy-duty Steel
  • Finish: Black Paint
  • Includes: Gaskets and hardware

These headers are a staple for enthusiasts looking to get more out of their classic GM vehicles. By replacing restrictive cast-iron manifolds, these headers allow for better exhaust scavenging, which translates to improved throttle response and increased power throughout the RPM band. The 1.625-inch primary tubes provide the perfect balance for street-driven trucks, ensuring you maintain low-end torque while gaining power in the mid-to-high range. The 3-inch collector is designed to integrate seamlessly with standard exhaust systems, making installation straightforward. Built from high-quality steel and finished with a durable black paint, these headers are designed to withstand the rigors of daily driving and weekend hauling. Whether you are working on a C10, K10, or a Suburban, these headers offer the fit and function you expect from a leader in exhaust technology. Enhance your vehicle's performance with quality parts from GGCRACING.
