FORGED U-bolt yoke, 1350, 26 spline.  Made for the D44/GM 10 bolts of the world, or anything else that's 26 spline and needs a U-bolt (D300).  The OE cast version fails, and they only came in a 1310.  We use precision machining and high strength forging techniques to make this yoke fit perfectly, and hold up to abuse.  It uses U-bolts to fasten the u-joints instead of straps.

Why the yoke is great:

• FORGED will beat the same part made from billet, or cast...period.  The forging process forms the metal grain along the contours resulting in a stronger part. Forging also compacts the grain structure which nearly eliminates failures from voids or inclusions.
• U-bolt style is superior to straps in nearly every way.  The U-bolt is nearly impossible to shear, but the head of a 5/16" bolt in a strap can pop like a pimple.  There's nothing to peel back on a U-bolt, but the strap can get caught.  Plus the U-bolt is simple to identify, a 1410 u-joint takes a 1410 U-bolt.  Straps have all sorts of different lengths, widths, and thread pitch differences for the same size u-joint depending on application.
• FULL LOCK UP is what we call our u-joint cap retention method (see pictures for FULL LOCK UP vs little tang).  Almost all yokes have a little tang to retain the u-joint cap.  Catch that tang on a stubborn rock, and it breaks off.  Then the cap shoots out, and BAM.  FULL LOCK UP eliminates this problem by fully retaining the u-joint cap.  
• OE spline fitment is what every yoke should have.  Most yokes slide on, and aside from a gross error, work just fine....BUT an OE spline fitment requires encouragement from a 3 pound dead blow.  It would take hundreds of thousands of miles to wear out splines, but we make them so they'll NEVER wear out.
