Drive Shaft & U - Joints

Driveshafts Do I need anything special?

Bent(creased)my stock driveshaft(70'cuda'automatic trans)so I need a new one.I'm not concerned with running stock parts but is there any reason not to get a used one for this application? Suggestions?

Some spicer u-joints with appropriate yokes would be nice. The ones larger than the 7290 bigblock joints. The Spicer 1350's. I'm running a 3" steel shaft (heavy as hell unfortunately) with the 1350's. Got mine from Hensley Racing. Expensive from them I think, the shaft with front yoke, a rear yoke, and 2 u-joints ran me about $450. I shouldn't ever have a problem dropping a shaft again....

I run a 3" driveshaft. Made with DOM tubing and I use 1350(bigger than 7290)series NON GREASEABLE u- joints. The DOM is stronger tubing than standard 3" steel. The 1350 is a larger,stronger u joint. The reason they are not greaseable,I broke the greaseable ones. just find a good local driveshaft shop. Any shop can build you a sufficient driveshaft. I run the same thing on the racecar and it makes over 1300hp on the bottle Good luck!

Mike, Dennys nitrous ready shaft is what I have in my car. That is what they reccomended for my horsepower level, even tho my car does not have nitrous. It is a stout unit that has the 1350 ujoints. I think it was 300 something dollars on sale. The stock driveshaft with the inertia ring (much thinner tubing) is on the shelf for future use.

Precison Shaft Technology built my d-shaft. It's a 3" DOM steel tube with a new 1350 series trans yoke, Brute Force non-greaseable u-joints. Rear u-joint is 1330 series. I paid $287 out the door.
