It’s been almost 60 years since GM debuted the re-designed 1955 Chevy that would spark the Tri-5 movement. To this day, the 1955 to ’57 Shoebox is one of the most desirable classic cars to own. While purists tend to keep them in era-correct showroom trim, re-powering the Tri-5 with a modern LS based power plant has become so popular, that Hedman Husler Hedders, located in Alpharetta, GA, has designed and now manufactures, a very comprehensive collection of vehicle specific LS swap headers and polyurethane engine/transmission mount kits for classic Bowties with an LS swap... including the coveted Tri-5 models.
Husler's mid-length and long tube design LS swap headers are engineered alongside their companion LS conversion mount kits, to ensure they fit properly when you start putting wrench to bolt in your garage. The most popular of Husler's Tri-5 header variations is the hybrid 1-3/4" mid-length design, which provides the added ground and engine compartment clearance associated with a shorty-style hedder, while offering performance increases that rival their long-tube counterparts. These mid-lengths come fitted with Hedman's gasketless ball/socket style collector.
For applications where something other than a mid-length style header is desired, Hedman Husler's long tube models are available with 1-3/4, 1-7/8 or 2-inch primaries, and a 1-7/8" to 2" stepped model is even available for those seeking the most performance gains. Husler's long tube Tri-5 header models have 3" slip-on style collectors.
All of Hedman Husler's Muscle Rod Hedders have beefy 3/8-inch-thick flanges that keep the mandrel-bent primaries firmly attached to the engine, even under harsh competition conditions. Husler offers the choice of either unfinished, silver high-temp ceramic-metallic coating or a unique flat-black Black Maxx hi-temp ceramic-metallic coating. Included with the headers is mounting hardware, O2 bungs, gaskets and installation instructions. Mid-lengths also include a weld-on style ball & socket collector adapter for your exhaust.
