GM 4L60E series reaction shafts used in high-torque applications and especially in heavy vehicles suffer from two common issues that require replacement: The splines that engage the rear planet can twist and the splines that engage the ring gear fret/wear. OE and other aftermarket versions are made from lower strength, plain carbon steel. Sonnax heavy duty reaction shaft 74602-01K is made from high-strength chromoly steel alloy to eliminate spline twist and spline wear.

The shaft kit includes a shim and two bearings. One bearing is for the shaft-to-reaction shell, the other bearing plus shim combination is for shaft-to-front carrier and makes it a universal fit for all input carrier styles. This includes all four- and five-pinion carriers found in early 700-R4, 4L60-E and 4L65E units including the Sonnax 2.84 ratio six pinion input carrier kit as well as late-style four- and five-pinion 4L60E and 4L70E carriers with lip-style bearings.
