Speedmaster PCE695.1001 TH400 Billet Aluminum Center Support with Oversized Intermediate Piston

The Speedmaster PCE695.1001 is a high-performance upgrade designed for GM TH400 transmissions operating in high-power and competition applications. This precision-machined billet aluminum center support with oversized billet intermediate piston provides enhanced durability and performance where it matters most.

Key Features:

• CNC-machined billet aluminum construction for superior strength and heat dissipation
• Oversized intermediate piston increases clamping surface area for improved second gear clutch pack holding power
• Bronze bushing design virtually eliminates premature sprag failure common in stock center supports
• Increased piston diameter applies greater clamping force to prevent clutch slippage under aggressive power curves
• Highly recommended for racing, drag racing, and high-horsepower street applications
• Direct replacement for factory TH400 center support assembly

This upgraded center support addresses one of the critical weak points in the TH400 transmission when subjected to increased power levels. By increasing the intermediate clutch apply area and incorporating a durable bronze bushing, this component significantly reduces the risk of transmission failure during hard acceleration and competition use.
