Direct replacement for 1979 - 1981 Foxbody Mustang!

This crossmember is designed to fit the narrow (2 ¾") mounting bracket of the 79~81 Foxbody Mustangs and  requires No modifications. This unique single tube design 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 both automatic (*PowerGlide & *TH-350) and manual (T-5, TKO & TKX) applications.

Works 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 the polyurethane bushings can be replaced by optional solid bushings.

  • Single tube design for maximum stiffness without excess weight.
  • Easily adjust for *PowerGlide, *TH-350, T-5, TKO & TKX transmissions.
  • Engineered to maintain pinion angle when using either OEM or aftermarket transmission mounts
  • Supplied with polyurethane bushings or can be replaced with solid mounting bushing for racing applications.
  • Allows more exhaust clearance than OEM style.
  • Direct fit on all 2.75" wide crossmember mounts, No modifications required.


  • *TH-350 & PowerGlide require additional spacing due to a shorter mounting pad height. Use Stifflers mount adaptor (TM-M02) and transmission mount (300-ES31108G).
  • * TKO & TKX require additional spacing due to a shorter mounting pad height. Use TKO Install Kit TCB-TKO to maintain proper driveline angle.
