The MEZIERE Torque Converter Shims 3-pack (FPS437187) is a precision-engineered solution designed for fine-tuning torque converter clearance and stall speed characteristics in high-performance automatic transmissions. This product is ideal for automotive enthusiasts building street machines, drag racing platforms, or optimizing shift quality in performance cruisers.
These shims allow users to adjust converter-to-impeller spacing without the need for expensive full replacements. By modifying internal clearances, they enhance fluid coupling efficiency, lock-up timing, and stall characteristics, which are critical for improving transmission responsiveness and durability. Manufactured to exacting tolerances, these shims can be stacked in various configurations to achieve the desired performance.
Serious transmission builders, engine tuners, and performance shops will find these shims particularly valuable when upgrading engine power or addressing specific shift lag or converter slip issues. The three-piece set allows for experimentation with different stack combinations, making it an essential tool for dyno tuning and transmission testing in both manual and automatic torque converter applications.
