Headers For Installing An LS Engine into 1967-87 CHEVY/GMC 1/2-3/4 Ton TRUCK/SUV (2WD Only); 1-3/4 in. Diameter, Mid-Length Tube; 3 in. Ball & Socket Collector- HTC Polished-Silver Ceramic Coated, Mild Steel Construction
Hedman Hedders has been manufacturing quality headers in the USA since 1954, and they've been manufacturing long and mid-length tube headers for Chevy & GMC Trucks for decades, so designing a good fitting, great performing set of headers for the popular LS engine swap was a no-brainer.
Each set uses smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next. The stout 3/8" header flanges ensure a great seal that will resist warping, and Hedman's unique, gasketless ball and socket collector design allows your 1/2 or 3/4 ton Chevy/GMC's exhaust system to bolt up, even if it is not perfectly aligned with the header collectors. Hedman is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty. The tough, polished silver HTC ceramic coating on these headers is good up to 1400 degrees. It helps keep underhood temperatures down, and prevent rusting of the headers. Unlike chrome, this finish will not "blue" or discolor. The coating is warrantied for 5 full years.
- Handcrafted, Mild Steel Construction.
- The Mid-Length Tube Header Design Provides Significantly More Low and Mid-range Power than Cast Manifolds, and Provide Better Ground Clearance And Component Compatibility Than Long Tube Headers.
- Ball & Socket Collector Design requires No Gasket, and Allows For More Exhaust System Misalignment than Old School, Gasket-Style Header Collectors
- Includes All The Necessary Mounting Hardware, Gaskets and Reducers (exhaust adapters)
- Limted Lifetime Warranty On Construction, Five Year Warranty on Factory-Applied Header Coating!
- Proud To Say, Made In The USA, Since 1954!
