The Beast Sun Gear Shell 700R4 4L60E Reverse Reaction

The Beast Sun Gear Shell for 4L60 4L60E 4L65E 700R4 GM Transmissions is a must have upgrade for your transmission rebuild, especially for heavy duty applications.  The factory part is known to wear after extended use, and causes the loss of reverse and makes shifting difficult.  The patented upgrade by ProSelect and Seal Aftermarket Products (SAP) increases the Sun Shell's durability and performance, which leads to a longer transmission life.

The OEM reverse reaction sun shell that came in your transmission is a common failure point.  This BEAST Sun Gear Shell has been redesigned to eliminate cracking and breaking with a reinforced neck collar spine made of heavier and thicker material to eliminate fatigue failure. Prevents loss of reverse, second and fourth gears. Rebuild with the Beast.

This is the Genuine Beast from ProSelect. Manufacturer suggests replacing the inner sun gear bushing when installing this shell. Washer installation is shown. The original metal washer or bearing between the front annulus gear and sun gear are not affected. "The Beast" replaces both washer and bearing style shells. The washer is NOT included in this listing. Contact us if you need one.

We recommend the Beast SunShell, aka Sun Gear Shell, if you're considering a rebuild for your GM 4L60E type transmission.
