This driveshaft was developed using components engineered by Fomoco originally for vehicles with the 5R55S transmission and 31spline limited slip 8.8 differential which is what the 05-up GTs also have.

"I love Motorz! I have watched every episode pertaining to trucks, as I have an F-150 2wd and have considered each of the upgrades covered--I find this extremely helpful. I too will be working from a shop with NO power tools. I am totally AMPED about AMP power steps, and I plan on doing them soon, confident that I can install myself thanks to the information gained here on the Motorz videos."
