Hedman Hedders, along with its Hedman Husler race header division, have been manufacturing quality headers in the USA since 1954. Hedman has been manufacturing long and mid-length tube headers for Chevy Tri-Fives for decades, so designing a good fitting, great performing set of headers for popular LS engine swaps is nothing new.
These mid-length design LS swap headers fit 1955-1957 Chevy Tri-5 Cars (150, 210, Belair, Nomad). They have a mild steel construction, and use smooth flowing, 1-3/4 in. diameter, 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 the unique, gasketless ball and socket collector design allows your Tri Five Chevrolet's exhaust system to bolt up, even if it is not perfectly aligned with the header collectors.
These headers have Hedman's high temperature, BLACK-MAXX satin-black ceramic-metallic finish that withstands exhaust temperatures up to 1400 degrees F, and looks great. Hedman Husler confidently backs these headers with a One year warranty.
