This adjustable crossmember is designed to fit within 30 to 34 inches of frame rails and can be secured by bolting or welding, offering versatile fitment options. Constructed using a patent-pending process in the USA, the X-Factor Stretch crossmember features a modular design utilizing hot-pressed T-6061 aluminum for exceptional strength and light weight, making it suitable for both street and track use. The unique end supports are made from high-strength steel. All components are powder-coated in a metallic aluminum finish, including the aluminum center section, steel end supports, and grade-8 hardware. This crossmember is compatible with a wide array of applications, including classic 4-speed transmissions, modern 5 and 6-speed transmissions, as well as vintage and late-model automatic transmissions.
