These gears feature substantially increased face widths, which are easily noted when compared to a like-speed gear from an original T-56 (as shown at the bottom left).<\/span><\/strong><strong><span style=\"color: #808080;\">Also especially noteworthy is the fact that these new speed gears benefit from a significant advance in manufacturing techniques\u2014two-piece laser beam welded construction.<\/span><\/strong><strong><span style=\"color: #808080;\"><\/span><\/strong><strong><span style=\"color: #808080;\">Past units were one-piece forgings that suffered machining limitations.

Strength benefits are obvious and abundant. This larger shaft not only resists distortion far better than previous designs but also prompted the use of larger bearings in all critical support areas for extraordinary stability.
