TCI Automotive 1.69 Ratio Bolt-Together Shorty Powerglide 27 Spline Planetary Set. 747611

Description:

This cleverly engineered bolt-together design is available in several gear ratios and shafts, making it the most versatile planetary unit for every racing configuration. The output shafts and gear ratios can be inspected and serviced easily without being sent back to TCI. The gears are precisely manufactured from heat-treated 9310 steel to provide the strongest, lowest friction and quietest gear set on the market, capable of withstanding any racing environment. Also part of this redesign are steel-backed, bi-metal washers with a wear-resistant PTFE layer that will reduce friction, and therefore reduce heat. Furthermore, the planetaries feature roller thrust bearings instead of washers for the sun gear and input shaft.
