Description
Factory steel driveshafts add unnecessary rotating mass and limit your S197 Mustang's performance potential. When you've upgraded to a TREMEC T56 Magnum XL, the last thing you want is the stock shaft holding back throttle response and acceleration. This custom aluminum driveshaft eliminates that bottleneck while delivering the precise engineering your swap demands.
Built from 3.5-inch diameter aluminum tubing with .125-inch wall thickness, this shaft achieves substantial weight savings over steel while maintaining exceptional torsional strength - aluminum driveshafts typically save about 1.5 pounds per foot compared to steel equivalents. That reduced rotating mass translates directly to quicker revs and improved acceleration, whether you're running the street or the strip.
The 31-spline Sonnax slip yoke sets this driveshaft apart from budget builds. Sonnax yokes are forged from chromoly steel - not cast - and undergo precision machining for exceptional balance and minimal runout. Each yoke is leak-tested to 40 psi with an O.D.-ground seal plug for superior transmission seal contact. The black oxide finish resists rust and pitting, while the 1350 series U-joint capacity handles serious torque loads without becoming a weak link in your driveline.
Compatible with 2005-2014 Mustang GT and GT500 applications equipped with 4.6L or 5.0L engines mated to TREMEC T56 Magnum XL transmissions. Each driveshaft is custom-built to your exact measurements - simply submit the completed Driveshaft Build Sheet to info@moderndriveline.com after ordering. Made in the USA with lifetime technical support.
