Is there any advantage from one to the other? I didn't see anything about how much each one weighs. I was going to get the chromoly one but I'll never make over a 1000 hp. 800 MAX.

I dont think you need a chromoly drive shaft. Talk to Bob at brute speed. The pst drive shaft is a 3.5 inch aluminum shaft that is rated at 1000 hp.

This is the only question I haven't annoyed Bob with, lol. I was just wondering if there was a weight difference between the two? The chromoly one is only 30 bucks more so I was going to go with it. Then again I was thinking about going with just the aluminum one cause it's nice looking. Polished vs black. ha

Not a problem, Ryan. I'm not sure what the weight difference is, but I see from your order sheet that you went with the alum one. I think you made a good choice. Thanks for the order! Bob

There is around 5 pounds difference between the three with the Aluminum one being the lightest. We have weighed them here in house before with the ones we stock.

Is the PST DS diameter any different than the stock driveshaft?
I was concerned about clearance issues with my exhaust ORY (current) TD (future)

Sorry if this is a hijacking

Depends on which one you get I'd assume...I think the aluminum version mentioned above is 3.5", so that is 0.5" larger in diameter than the stock DS (it is 3"). I would guess their steel offering is 3", but don't know for sure. I have a 3.75" DS, and don't have any clearance issues to speak of, and I was even able to get a safety loop to fit.

PST steel is 3"
PST aluminum is 3.5"

Thanks, just looking to get an understanding of what I may need to look out for in my 9" rear and TD exhaust plans.

The PST 3.5" aluminum driveshaft is only .25 larger on any given side. Driveshaft safety loops and exhaust normally clear without any problems. Bob

mine didn't clear the loop on my UMI torque arm. btw what is the length supposed to be on the PST 3.5" driveshaft that is to be used with a 9in?

PST rates it at 1000hp.

We have also not had any fitment issues with drive shafts and our safety loop. Our bolt in drive shaft loop also has great ground clearance as well unlike others on the market.

yea i had an issue with the UMI loop, they have the loop about an inch too high! I had to shim the crossmember down (closer to the ground ) about 1/2" to clear the pst 3.5" shaft. Everything went on at the same time, it wouldn't have cleared the stock shaft either I don't think and my car is SLAMMED. That was with the stock T56. When I put the TH400 in I just shimmed the trans mount up another 1/4" or so for clearance and removed my TA mount shims, along with doing a 3" CM shaft. haven't measured the driveline angle yet...

safety loop was the least of my concerns with the PST. mine seemed just a little too long for my Moser 9 inch, about 1/2" too long, but it worked. my car is also a cam only car, making 412rwhp, but managed to twist the splines on the slip yoke. guy at PST was cool about it & sent me a new one ASAP. now just a couple weeks ago i thought i had a bad u-joint. once i got the driveshaft off the car & was able to push one of the caps through the driveshaft fairly easy, i figured i would just go with a different brand driveshaft.

Sounds like a fluke piece. But being to long sounds to be main problem.

Were the caps on the joint coated ? if not that will be an issue on an AL shaft and cause a problem, vibration or break
