• Year Range: 1982-2013

This HD clutch pack is the perfect replacement for the commonly burned 3-4 clutch pack. This high energy powerpack is a must for high HP, heavy abuse applications, but is recommended if you just want to increase the life or durability of any transmission. Stock, these transmissions have between four and six clutches in this pack and never have the right clearance for proper shift quality.

With this kit you will be able to increase the friction surface area 50%, to nine clutches. Plus, you will have selective plates that let you customize the clearance to the desired amount.

The HD kit comes with everything that you will need to complete the conversion, including a new special snap ring and pressure plate.

The directions that are supplied give all the necessary info, including the required clearances.
