i prefer the yokes...

 

That's cool, but why?

 

Was looking at this yoke, but not sure if it's a waste of $$ or overkill

stronger and easier to get the drive shaft out

 

Also, the stock 8.8 flange only allows a 1330 u joint. Some use a 1350/1330 hybrid joint on the DS. Im not a fan of that. After market yokes allow a proper 1350 joint.

 

Consider safety first, there is no such thing as overkill in this aspect.

 

The rear end build consists of the following...

33 spline true track limited slip
3.73 gear
9" bearing ends
Billet main caps
Aluminum girdle cover
Tubes fully welded

Based on this build with a chrome moly yoke. How much power should this axle handle without issue?

 

Whats the weight of the car? Trans? Tire?

 

3200lbs
T56
Hoosier drag radials (295/55/15) 28" tire

 

being on a stick and a radial i would do it for sure

 

The Strange are ok. But I will take the Mark Williams yokes on both ends any day. And I double that for a stick car.

 

I use an aftermarket dual pattern steel flange that takes big or small pattern yokes for big or small joints.

I ran the small joint for a little while but changed to a big joint. My car is 3200 lbs. I did a 1.1670 60ft time last weekend.

My 35 spline axle splines have just a little twist in them, but the pinion flange is good and looks like new. To me, the flange looked better than the yoke. I had them both side-by-side and went with a dual pattern flange. The driveline place that built my custom driveshaft also prefers the flange. They do a lot of mud trucks and drag cars in the Atlanta area.

 

My drive shaft for my Capri that came in my T56 magnum trans kit I am pretty sure is a 1350. It is a real pain to get the bolts in it with the stock flange. The joints are huge compared to stock ones.

 

The only thing I see with a flat flange yoke that has any strength at all is the bolts themselves. Flat flange yoke is still cast iron when it is all said and done when it takes the hit.

 

I have never broken a flange , but have broken several yolks over the years .
The U joint is usually the fuse , and I run a drive shaft loop for that safety margin .

 

Flange relies on friction. Yokes don't.

Put a Mark Williams yoke in and stop that voice in the back of your mind nagging you at the double bulb.

 

That is almost totally backwards.

The flange places the four thick bolts almost entirely in shear. The bolts act like pins in shear, and that is what prevents yoke rotation on the flange. You can grease the joint between the flange and yoke barely have a change in strength. The limiting point in a flange is the strength of the yoke or the splines on the pinion. The four bolts in shear are rated about 25,000 pounds each.

The standard bolted U-joint yoke relies on U bolts in tension to retain the cap. The saddle itself cannot go more than halfway across the cap, so it shares the load equally with the U-bolt. It pushes sideways on one U-bolt leg placing it in shear and tension as the U-joint cap tries to roll out of the saddle.

You have only two smaller bolts in tension and shear trying to do nearly the same job as all four larger bolts on the flat flange joint.

 

Strange chrome-molly yoke vs Mark Williams? The strange is like $50 less, just wondering what your getting for the extra $$$

 

we have been 1.121 60' with the back tires off the gas at .9 @3175lbs with a strange yoke.... it will be fine. the mark williams stuff is nice but some times i wonder if its just the name on some of it

 

The reason I didn't care for the Strange is because I had to do some careful fitting up with the yoke cap fitments. They didn't come down on the u joint caps properly till I removed some material from the yoke. Maybe they fixed that issue. Other than that it was just fine. But I have run both manufactures front and rear yokes. Just a preference for the Mark Williams. They will both do the same job however if price is the deal maker.

 

Flange relies on friction. Yokes don't.

Not so .
To each their own .

 

I went with the chrome molly strange yoke and there HD girdle caps

 

2 flat pieces of metal clamped together by 4 bolts.
The clamping force from the bolts creates friction.

The force of friction is greater than the shear force of the bolts.
The shear force on the bolt is no where near 25,000 each.
