American Powertrain takes the guesswork out of chassis reinforcement with their X-Factor stretch crossmembers. These T-6061 aluminum braces are lightweight and strong—perfect for street or track applications. Their unique end supports are constructed of high-strength steel. And because the stretch crossmembers are offered in several adjustable sizes, they provide a wide range of fitment possibilities, with excellent clearance for large diameter exhaust tubes. All models are silver powdercoated for protection and include Grade-8 hardware; you can either bolt on or weld the supports into place. X-Factor stretch crossmembers come with a lifetime warranty against breakage. Applications include classic 4-speeds, modern 5- and 6-speeds, plus all vintage and late model automatics. Choose the width that best suits your project.
