KDE Direct Thrusted Metal Bearing V2 Block Set (T-Rex 550)
Smart design that from an engineering perspective is more correct than stock. Radial bearings are not supposed to be laterally loaded. These allow less power loss during hard pitch pumps, and extend your main shaft bearing life to... well... yet to be seen. But after many, many flights mine are still silky smooth. KDE's website is an absolute wealth of knowledge as well and provided beautiful full detail 3D CAD drawings of the parts and their assembly.

KDE Direct Thrusted Metal Bearing V2 Block Set (T-Rex 550)
This item is not just bling. Although the blocks by themselves probably will not provide better performance over the Align version, the 2 radial bearings are very smooth, and the thrust bearings are a welcomed addition. Other than saving money, I do not understand why the stock Align version does not include thrust bearings. Also, my stock Align radial bearings where too notchy.
