Chris Duke shows you how to install a Leonard Racing SpyderShaft aluminum drive shaft and a Steeda Tri-Ax short throw shifter on a 2008 Ford Mustang GT.
Regarding the bolts for the new drive shaft: Your stock Ford drive shaft uses 12mm bolts near the front, and 10mm bolts near the rear. For the installation of the SpyderShaft drive shaft you will not need the 10mm bolts, rather a new set of four 12mm bolts. If Leonard Racing did not provide these to you, get them from your local Ford Parts dealer before you get started.

In this episode we work on the drivetrain of our 2008 Ford Mustang GT (S197 2005-2009). We install an aluminum SpyderShaft drive shaft from Leonard Racing which is 33 pounds lighter than the stock drive shaft from Ford. As a result, it gives you more power to the wheels and also increases your fuel efficiency.
While we have the drive shaft off, it’s the perfect opportunity to swap out the shifter (since it is located directly above the drive shaft). We installed a Tri-Ax short throw shifter from Steeda which reduces your throw by a whole two inches, providing faster & firmer shifts and a guarantee to make 3rd gear.
The format of the show is to install everything in the MOTORZ garage in order to properly show you, the viewer, how easy it is to do the install yourself in your own garage, using a few simple tools. However, due to the low stance of our Mustang and all the camera work we needed to do below the vehicle as well as in the cockpit, it made better sense for us to film this episode in a different environment, with a lift and minimal power tools.
While we typically use all hand-crank tools on the show, there was one step where that was not possible. When removing the pinion nut from the differential, a breaker bar just wasn’t enough. So for this step we do recommend you use an impact gun (air or electric) otherwise it’s just impossible to remove. Also be warned that putting the pinion nut back on requires 125 ft-lbs of torque, so pick up a beefy torque wrench to get that sucker back on there.
Removing the stock drive shaft is fairly easy. There are four bolts near the front, four near the rear, and two that hold a bracket on near the center. Those all have to be removed, in addition to the pinion nut I just mentioned in the previous paragraph. After swapping out the stock flange with the aftermarket one, you can install your new drive shaft… unless your goal was to also upgrade your shifter while your drive shaft is off. Obviously it goes without saying… if you don’t upgrade your shifter at this time and want to do it later, you’ll have to remove your drive shaft (again) and most likely replace the bolts. Now you know why we did the shifter during the same install! Be sure to watch the end of this episode for some tips when it comes time to install the aftermarket flange from Lenoard Racing. If you botch this step up you can cause a ton of damage to your rear end.
Upgrading the shifter is also a straightforward process. After removing the shift knob and loosening the boot inside the vehicle, crawl underneath and loosen all the bolts that hold the shifter in place. Then assemble the new shifter and install it into place where the stock shifter once lived.
The combination of both upgrades is very noticeable… and both worth the effort! There are too many details to mention here, so just watch the video for the step-by-step!
Oh yeah, and a special thanks to Mike Wilkes for sending us his old Mustang parts to install on Jason’s Mustang. This made for a great episode!
