Anyone have any experience with these? Good, Bad, Indifferent?

Thanks!

I had a PST drive shaft on my SRT 6.1 Challenger and it was great.

PST is not the one you would want for your Hellcat. They need to do more R&D
I know of a car that had a catastrophe fail most likely caused by a PST ds.

Too late now. Already purchased and installed. It was custom fitted.

“Custom fitted” is key imo. Supposedly the flange to flange dimension can vary by up to almost a whole inch from one challenger to another. I installed the sonnex flanges on mine, got a center to center dimension for the caps, and had the shaft made .440” short

Having a shop that can balance the entire unit, u-joints and the sonnex flanges, is just as important to me

Welding a bar (on the exhaust) will help keep the shaft in the tunnel should it break but as long as it never contacts anything I don’t expect to run into that anyways. Enjoy : )

My shop has used PST for a long time with great results. The required measurements BEFORE building. Then it showed up in 2 days.

The extent of the damage done by the exploding stock driveshaft:

Replace 2.62 Diff
Installed Control Arms and Diff Braces
DSS CV Axles rated @ 1200hp
PST 4" Aluminum Driveshaft, custom built
BMR Cradle Lockout Bushings
Rebuilt Transmission
Exhaust Control Valve Actuators

Pending: New ECM.

Sad thing is the car will be raced only occasionally if at all. I can't afford any more breakage.

So all of that stuff broke or?

Drive Shaft exploded, taking out Diff and Cracking tranny case. So all of that stuff has been installed to prevent wheel hop and a recurrence. Waiting for now ECM - the one in the Cat seems to have gone bad.

Ask your shop how many other customers they have installed a PST Driveshaft in a Hellcat?

I can %100 agree PST is a Good company and I had one installed on my 2010 SRT8 6.1

Maybe they are past more R&D now or they needed the measurements because you have one of their newer types.

I was actually wondering if you were asking about PST because you had one installed and if that was the one that exploded.

But I see it was a stock one.

Apparently she has me blocked

Just get a Redeye driveshaft, set it and forget it.

I've seen other members use the Redeye DS with great results too!
