I looked at one of these this weekend at the BBQ in TX and they are very nice. Spherical bearings are added to the new beefed up ends and should outlast the rest of your truck. One of the guys in our club had nothing but trouble with his Calmini system and is running this without any issues. I am running the Calmini system with the spherical bearing mod and it works well for me.
I would definately recomend this centerlink to anyone who was interested in the L&P setup. I think these are nicer than those L&P was building.
