Builders of Mustang driveshafts who want to upgrade from a 1330 U-joint have long had to make due with purchasing an extra adaptor flange to allow installation of a 1350 flange yoke. Now, with Sonnax flange yoke T3-2-949A, the days of sourcing an extra adaptor are over. The Sonnax yoke is forged and precision-machined to accept a 1350 U-joint while maintaining compatibility with the OE 3.5 inch bolt circle.

  • Lowers build cost
  • Reduces rotating mass with elimination of adaptor flange
