OK, so I have been working and testing these for awhile. I know I for one was tired of breaking those cheap $5 kit type formed straps holding in my U-joints. I upgraded to 1350's when I put the Stak in the EB. What I found though was there was only one style of yoke in the 1350 for the Dana 44 front I was running. And unfortunately it was the strap style not the u-bolt style yoke. So I said there has to be something better? Well I couldn't find it. So I started looking at costs for upgrading other yokes from straps to u-bolt style for other axles. What I found was that it would cost you $80 + to upgrade the whole yoke plus on most you had to add the u-bolts at another $10! So for a bill you could upgrade one yoke (if they made it for your axle which mine they did not). I sell these in sets of 2. Thats enough to complete one yoke. These work for both 1350 and 1410 strap style Spicer yokes. My testing amounted to shearing off a Dana 44 pinion in the process. However the Spicer u-joint and our girdles w/ the caps held up just fine!
