Description
When you drop a 700 lb-ft-rated TREMEC T56 Magnum into your Fox Body Mustang, your factory driveshaft becomes the weak link in the drivetrain. This custom steel driveshaft eliminates that bottleneck with proper engineering for serious power applications, matching the Magnum's output shaft and your Ford 8.8 rear end with purpose-built components.
Built around a 3.0-inch steel tube, this driveshaft delivers the torsional strength and rigidity needed to handle the Magnum's increased torque capacity without deflection or vibration. The forged steel slip yoke interfaces directly with the T56 Magnum's 31-spline output shaft, while 1330-series universal joints provide the strength upgrade your build demands. The Ford 8.8 small flange configuration bolts directly to Fox Body Mustang rear ends without adapter hassles.
Each driveshaft is custom-built to your exact specifications using our comprehensive build sheet process. Submit your vehicle measurements after final assembly--transmission installed, rear end in place, at proper ride height--and we'll build a driveshaft with correct length, phasing, and balance for your specific combination. Professional high-speed balancing and black paint finish complete the package. Compatible with 1979-1993 Fox Body Mustangs equipped with T56 Magnum transmissions and Ford 8.8-inch rear ends with small flange configuration.
