I need to replace the Yoke to a 7290 10-spline on an 8 3/4.
I was going to just buy a new one, but prices are all over...for what i would think would be a fairly common design.
Seems anywhere from about $70 to $150.
So, why the price swing? (other than some companies are just more expensive..spare me the obvious)

There maybe three grades? Stock, Forged, Billet?

I'd like to "spare you the obvious" but most all of them are the same yoke from the same foundry from what I've seen. Mancini has the middle of the road price at I think $135 Other suppliers sell the same yoke for more and some for less.

hi
you said replace the yoke TO a 7290 .


soooo do you now have a 7260 ?

if so just get the u joint that is 7260 x 7290 and save some money and time .

several brands have them !

I was under the same impression. I went to a 7260 billet yoke with u-bolts and solid Spicer joints after an OEM yoke "spread" & broke. Never a problem since then.

some have good luck using the 7260 joint/yoke combo, while others go to the big guy 1350 size.
any idea where the sizes fit in with hp/tq in say, the average B body ? assuming a good yoke and solid joint ?

Difficult to say because there's a lot more to it - weight, traction, torque, stick/auto, etc. Same situation with how well an 8 3/4 will hold up. (ring & pinion and caps). A heavier, dead-hooking, higher HP/torque combo will eventually find the weak link in the "chain" - output shaft, slip spline yoke, u-joints, driveshaft tube, rear end yoke, gears, caps, axles, wheel studs. My Dart at 3,540 + lbs pulls the wheels every run. Early on I found out the hard way that an OEM yoke can eventually spread, gets hammered from the movements & breaks, or just plain fatigue.

very true on all aspects you point out.
i guess a guy has to stand by this old, famous quote : "Do you feel lucky...........Punk ?"

You did not mention the issue with the one you have, so...... just in case;

If it is good other that the machined surface the seal rides on, redi-sleeves are available, easy repair.
