Description
Fox Mustangs upgraded with TKO or TKX transmissions need a driveshaft that matches the 31-spline output shaft while handling increased torque. This custom aluminum driveshaft delivers substantial weight savings over stock steel units, reducing rotating mass to improve acceleration and throttle response. Aluminum's natural corrosion resistance also eliminates the rust issues that plague steel driveshafts in daily-driven vehicles.
The forged steel slip yoke is a critical upgrade over cast alternatives. Forging aligns the metal's grain structure, making it significantly more resistant to cracking or failure under load - essential when you're transmitting power through a transmission rated for 600 lb-ft of torque. The 31-spline design matches TREMEC's TKO and TKX output shaft specifications exactly, while the 8.8-inch rear flange bolts directly to Fox Mustang differentials without modification.
High-speed balancing eliminates the vibrations that Fox owners know all too well, delivering smooth operation whether you're cruising at highway speeds or making a quarter-mile pass. The 1310 series universal joints provide reliable performance for street and moderate performance applications.
This is a custom-built driveshaft requiring precise measurements from your completed vehicle. Submit the completed driveshaft build sheet to info@moderndriveline.com with your tunnel clearance, overall length, and operating angle measurements before fabrication begins. Fits 1979-1993 Ford Mustangs running TKO or TKX transmissions with 31-spline output shafts. Made in the USA with lifetime technical support.
