Small Sprag Assembly -This is a our small Sprag, note the snap ring in the outer race and single brass thrust washer. Posted 6 days ago. Because the ring gears are the final gear ratio of 1:1, a six-speed planetary transmission would consist of 5-planetary sections: 5 gear set ratios (sun gears) and a sixth gear when all of the planetary gear sections are locked together forming a 1:1 ratio. Choice of standard or new generation reverses. The internal action of a LENCO is such that when the transmission is in first gear the dedicated planet gear assembly provides the launch ratio. The arm must be free to move in all directions. Lenco Racing Transmissions have brought more of their racing technology to the street crowd with a new transmission that is lighter, engineered with new technology, has more efficient components, and has less rotating mass than the previous unit.
