Review SPEEDMASTER Gm Billet Aluminum Intermediate Clutch Blocker Plate fits ELIMINATOR TURBO 400

The Speedmaster PCE676.1007 GM Turbo 400 Th400 Billet Intermediate Clutch Blocker Eliminator Plate is an essential performance upgrade for vehicles equipped with a GM 400 or Th400 transmission and a turbocharger. This billet aluminum plate is meticulously engineered to replace the factory clutch blocker plate, which is often inadequate for handling the increased clamping force and thermal stress caused by turbocharging.

This high-performance plate boasts several advanced features designed to optimize clutch engagement and durability.

The PCE676.1007 plate is specifically designed for use with GM 400 and Th400 transmissions and is compatible with both manual and automatic applications. Its precise fit and finish ensure a seamless installation process, making it an ideal upgrade for enthusiasts seeking improved clutch performance and reliability in their turbocharged vehicle.
