If the FRPP was still cheap...I'd say do it. But it's pricey now. A stocker that's balanced right is just as good. They only twist up if you have really big power or there's a kink/gash in it somewhere. I've seen some sick-fast cars with steel DS's.

... For the money you spend balancing a stocker just get the Aluminum. Less rotational mass.....strength isn't the issue. Anyone who has ever installed one knows the benefits and can feel it. It will eliminate vibrations you didn't even realize you had and it's a known scientific fact that less rotational weight means more power realized at the rear wheels...granted we are not talking a huge gain but every little bit helps.

I had my stock d.s. balanced and new u-joints installed for about $50, grant it this was a few years ago.

If cost is no factor, sure get the aluminum one.

If cost is somewhat of a factor, you owe it to yourself to find out how much a balance job on the stocker would be.

Also after a good balance job to the stocker, compared to the al, I don't think either one will be better for eliminating more vibrations than the other.
On mine I had seen speeds regularly of 150+ (5200 RPM in 5th gear) and had very little vibrations.

i think the u-joints will cost you more than that.

Read his first post, he has already replaced the U-Joints

of course you didnt mention if this was parts price included or just labor. just trying understand if i am clear on what you are saying. i will have to make this same decision in the near future. also where is closets place to have this done. i know there is not anywhere here in Gadsden area.

Thanks for clearing that up for me cupcake.


When I changed the "u"s noticed that 2 of the 4 bolts where the driveshaft meets the rear end were half way backed out - guess you can expect that with an old pony.

I have proof that I lost 5ftlbs of torque on the dyno when I went from a steel one to an Al. one. So all that gain in hp and tq is just a sales gimic in my book.
