RTS' TH400 Transmission Parts Kit is your go-to solution for upgrading an existing TH400 or enhancing a new aftermarket performance case. 

This kit includes a precision-crafted billet steel pressure plate, engineered to be thinner than the OEM TH400 cast iron variant. This innovative design allows you to fit up to five frictions and steels in the intermediate clutch pack, compared to the usual three or four. Whether you're working with your original TH400 case or an RTS or Reid aftermarket case, this upgrade offers enhanced capacity and performance for both.

The kit also includes a Torrington thrust bearing, specifically designed to minimize wear and tear, along with a breather and an assortment of other essential fittings and accessories.
