Stifflers 1982-1993 Mustang AOD/T5/TKO/TKX Tubular Transmission Crossmember

This unique single tube design for the AOD/T5/TKO/TKX transmissions adds stiffness and strength far beyond that of the OEM versions while offering versatility like no other. Simply slide the mounting sleeves and reposition the spacers to cover AODE, 4R70W, TR-3550, and C6 transmissions. The crossmember is engineered to work with OEM and aftermarket transmission mounts; all while maintaining your current pinion angle. Low deflection polyurethane bushings are used in the mounts to dampen driveline vibrations and noise. For racing applications, polyurethane bushings can be replaced by solid bushings. If additional vertical adjustment is required, offset bushings can be used to raise or lower the entire mount. Direct fit on all 4.5" wide crossmember mounts, 2.75" wide mounts will need to be relocated.
