7260 vs 7290

[mjb765]

Had an 8 3/4 489 center section built and the builder installed a 7260 yoke instead of the requested 7290. This car will be street driven with occasional spirited launches and driving (it's a 4 speed). Mostly stock 383 with a mild cam. Should I switch the yoke or am I OK with the 7260?

Thanks

Should be OK , I would use the conversion joint though so the shaft has 7290 on both ends

I was going to ask what size the driveshaft was....

I've done 4500 rpm launches with slicks on a prepared track with 7260 u-joints, so they are up to it. I tried to buy the most reputable brand I could find and got them with solid crosses, not drilled for lubrication.  I have broken them, but that typically happened when I got too much lift from the suspension and exceeded their operating angles. Then they grenade in spectacular fashion.

That was the plan.....the shaft has a 7290 in the back now. I didn't check what size the front was.

Thanks all for the info....

My 340 Challenger driveshaft was 7260 in the front and 7290 in the back from the factory so you won't be any weaker than that anyway.
