Steeda's 1979-2004 Ford Mustang driveshaft spacer eliminates the need to have custom shafts made for length deficiencies of 3/8" to 11/16" and greatly reduces the chance of slip yoke failure by maintaining proper engagement. This part was developed by Steeda Hardcore for the Renegade Mustang to fit a C4 transmission, but will also work in other applications where 3/8" to 11/16" extra length is required. The spacer is made from billet aluminum for lower rotational mass and includes grade 12.9 hardware.
