904 Reinforced Low Gear Set 2.74/1.54/1:1 - Includes Sunshell, new thrust washers and the planetary is Heli-Arc'd to reinforce the center hub.

These low gear sets lower the 1st and 2nd gear ratios while retaining 1:1 in 3rd.  Some are machined for Torrington bearings and are included in the sets.  These are ideal for heavier cars and lower horsepower engines.  They also help improve the 60 ft. times.
