48RE High Capacity Input Shaft and Piston Kit
Heavy Duty Billet Sonnax Upgrade.

The OE Input Shaft has many issues due to its Two piece design.
The OE design has splines that mate the shaft to the clutch hub.
These splines are Very weak and under High Horsepower / Towing Applications they have a tendency to fail.
Sonnax addressed this issue by engineering a Billet version of the hub and shaft out of 300M Forged Steel.
Engineering this from Billet Forged Steel eliminated that weak OE Joint.

Sonnax also Extended the Clutch Hub to hold one Extra Friction Plate / Clutch.
In doing this they designed a custom Anodized Billet Aluminium Piston that could support the additional
Steel Plate /Friction Plate / Clutch.

Adding this Clutch gives the drum more holding strength , and greater heat dissipation capabilities.

In This Three (3) Piece Kit You Will Recieve:

1 Billet Input Shaft W/ Extended Hub
1 Billet Anodized Thin Piston
1 Custom Thickness Steel


These Upgrades make this Sonnax Package Last Even Under High Horsepower and Towing Applications!
