PLANETARY 1.98 RATIO LONG

MIA's Description

The TCI Automotive 747620 1.98 Ratio Bolt-Together Powerglide 27 Spline Planetary Set provides the strongest and lowest friction gear set on the market. It features steel-backed bi-metal washers and a PTFE layer to reduce heat. The bolt-together design allows for easy inspection and servicing of output shafts and gear ratios without needing to send it back to TCI. The gears are precisely manufactured from heat-treated 9310 steel for strength, low friction, and quiet operation, capable of withstanding any racing environment. It also incorporates roller thrust bearings instead of washers for the sun gear and input shaft.
