Hedman LS swap headers are engineered to simplify one of the most common and powerful engine conversions in the performance aftermarket. Whether installing an LS engine into a classic muscle car, truck, or custom project vehicle, proper exhaust fitment is critical to completing a reliable, long lasting swap. Hedman Hedders manufactures application-specific LS swap headers designed to provide the clearance, exhaust flow, and installation compatibility required when transplanting a GM LS engine into a wide range of popular chassis platforms.
Since 1954, Hedman Hedders has built a reputation for precision exhaust products. More than 70 years after we started this journey, we remain 100% committed to building our headers right here in the USA. Hedman LS swap headers are designed to work with popular engine swap platforms including classic GM A-Body, F-Body, G-Body and X-body cars, C10 trucks, Suburbans, Tri-Five Chevys, S10 conversions, street rods, and all-out custom builds. By focusing on chassis clearance, steering component clearance, and a thoughtout collector placement, Hedman LS swap headers help make LS engine conversions cleaner and easier to perform.
Headers are only one aspect of your LS swap project, and you will require additional conversion components such as engine mounts, oil pans, transmission crossmembers, and accessory relocation brackets. Hedman Hedders and Trans-Dapt Performance Products offer a broad range of supporting swap components designed to complement our LS swap header installations and simplify the overall engine conversion process.

LS swap headers are exhaust headers designed specifically for installing GM LS engines into vehicles that were not originally equipped with an LS platform engine. These headers are engineered to provide proper clearance around steering components, chassis structures, and suspension systems that differ from the original LS vehicle layout.
Yes. When installing an LS engine into a different vehicle platform, factory exhaust manifolds often interfere with steering shafts, frame rails, or suspension components. LS swap headers are designed to route the exhaust properly within the new chassis while maintaining efficient exhaust flow.
LS swap headers are commonly used when installing LS engines into classic GM vehicles, C10 trucks, Tri-Five Chevrolets, street rods, S10 pickups, and many other popular engine swap platforms. The correct header design depends on the vehicle chassis, steering configuration, and engine mounting location.
Most LS engine conversions require additional components such as swap engine mounts, oil pans, transmission crossmembers, wiring harnesses, and accessory brackets. Headers are one of several components used to complete a properly engineered LS swap installation.
Hedman LS swap headers are available through authorized Hedman dealers and performance retailers nationwide. To locate an online or local retail speed shop, use our dealer locator to find a distributor near you.
Important Fitment Note: Unless otherwise stated in the information provided on this site, all Hedman Hedders are designed for use on stock cylinder heads. The use of aftermarket cylinder heads, or cylinder heads not original equipment on the listed vehicle, may result in component or chassis interference, as well as spark plug clearance issues. Always consult the cylinder head manufacturer before purchasing headers for use on aftermarket or non-stock heads, or contact the Hedman Tech Department at 562.921.0404 (Monday through Friday, 8:00 a.m. to 4:30 p.m. Pacific Time).
