I got my hands on some RCV axle shafts for the Dana 44 frontend in our '07 Wrangler Rubicon. These CV-style axles are supposed to be several times stronger than the factory U-jointed shafts. I've seen the test chart and they seem to be about the same strength as a stock 35-spline Dana 60 axle shaft. That's a pretty big upgrade for a simple bolt in!

 The other bonus is that they are virtually the same strength when the wheels are straight or with them turned. A factory-style U-jointed shaft is significantly weaker when the wheels are turned. We'll see how they hold up to everyday use and high-mileage. Look for a review in an upcoming issue of Jp Magazine. For more info about these new shafts and the TJ and YJ applications click HERE.
