Product Description

There are mainly four different types of joints for automotive U-joints as mentioned above.

How to determine the spline size?

Always measure the diameter of the shaft and calculate the number of splines on the shaft. To get the correct number of splines, use a flat edge, cover the shaft blank through the diameter, calculate the number of splines on the other half and multiply the obtained number by 2 to get the total number of splines on the entire circumference of the shaft.

This u joint is good quality and excellent price. Using on a 1954 chevy pickup. Needed the part and it is well made and rotates smoothly. Half the price of some other brands.

I had to file down the DD side some to get the shaft to go in. The coating is to thick. But other than that it seems like an amazing product and we'll made. I'll update my review when I drive the car.

Doesn't fit Dimensions like it says. I had to machine the 1" end out . Still working on it. 3/4 very tight also.

this joint only goes 35 degrees total , it should be 35 degrees on both ends = 70 degrees , thats the whole point of buying a double joint , or you can just buy a single joint ,
