Crossmembers - American Powertrain


Our X-Factor Crossmembers are a new take on transmission supports. Constructed from powder coated modular T6061 aluminum they are lightweight, super strong and each model is adjustable to fit a wide range of transmissions and vehicles. X-Factor provides the best support for your gearbox and looks great doing it. The competition likes to say that their steel lumpy and terribly welded crossmembers are stronger than ours. Don't believe the hype! We have ours tested on a cars over 1100 ft/lbs of torque strapped to a dyno with no flex. Our X-Factor Crossmembers are guaranteed for life! Does the company you're shopping at guarantee that? Shop Crossmembers
