Not the cheapest but the least likely to have vibration problems which is so common with all the other designs. The double universal joint requires precise alignment and if the splines loosen up you'll have vibration. Neither of those things are an issue with the PST for the Mustang. No splines used and only one universal joint the other end has a CV joint which eliminates both problems.
That seems like a simple fix to all the alignment issues. there must have been a good reason for Ford to use a 40+ pound double shaft and not this type of cv setup, maybe it was cost? if its worth fuel economy i'm surprised they didn't go for it.
I can tell you that you can feel the lash in the rear end something you could not feel when the shaft weighed 40 pounds plus. All rear ends have it just jack up one wheel and turn it back and forth with your hands you can feel it, a space where the gears don't touch. The wheel goes from turning stiff to easy when you change directions and back to stiff again that's the lash. When you back up really slow on a incline it can make some clunking noise once underway it stops completely.
Ford does use a CV joint to adjust the length of their stock shaft same as PST and DSS does.
That is what I have. It is rated to 900hp so no worries about that. Some of them are only rated to 600 or so. I am planning on putting on the eforce stage 1 from brenspeed which is rated at 560 bhp so I didn't want to chance it.
It is super easy to install, and I have no vibration problems.
+1 ^^^ I am running Dynotech on both my Snake and GT...perform perfectly
My wife has said she is wondering when she will be in the garage and the GT 500 will be in the bedroom...I tell her thats just crazy...there is no way to get the car up the stairs!
There is NO problem that can't be solved by the simple application of more Horsepower!!
