American Powertrain added XL Wide Universal Crossmembers to their X-Factor product offerings. This new X-Factor crossmember, available in silver or black, adjusts from 40- to 46-inches wide for wider full frame cars and trucks. The crossmember fits Tremec 5-speeds T-5, TKO and Tremec 6-speeds, T-56, and Magnum using a GM mount. 

Made in the USA using modular construction, all X-Factor crossmembers are constructed from hot pressed T-6061 aluminum, making them incredibly light, exceedingly strong, and perfect for street applications. Each model is adjustable to fit a wide range of transmissions and vehicles.

All X-Factor crossmembers come with a lifetime warranty against breakage.
