1/4in Motor Plate Spacer Kit

The 1/4in Motor Plate Spacer Kit (TCI 745504) is a precision transmission accessory designed for serious drag racers and high-performance enthusiasts who demand tight control over converter geometry and engine-to-transmission alignment. This spacer kit addresses a critical need in modified vehicles: maintaining optimal spacing between the engine block and the torque converter's mid-plate to ensure consistent engagement, reduce parasitic losses, and maximize power transfer to the wheels. Whether you're running a dedicated competition setup or a street-legal performance build, proper motor plate spacing is non-negotiable for reliability and repeatability.

Built to TCI's exacting standards, the 1/4in Motor Plate Spacer Kit works by inserting a precision shim between the motor plate and the transmission bellhousing, effectively offsetting the converter's position by a quarter inch. This level of precision is essential when running high-stall or competition converters, where even minor misalignment can lead to binding, premature wear, or catastrophic failure under load. The kit's compact footprint (2.8 x 2 x 4.1 inches) and lightweight construction (0.67 lbs) ensure minimal impact on vehicle balance while delivering measurable improvements in converter engagement and driveline efficiency. Designed to work seamlessly with TCI Competition Converters, this spacer maintains the tight tolerances necessary for professional-grade performance.

This kit is essential for transmission builders, race teams, and hardcore enthusiasts upgrading to aftermarket converters or experiencing clearance issues on custom engine blocks. Installation requires basic mechanical knowledge and proper alignment procedures to ensure the spacer sits flush and centers the converter correctly. The 1/4in Motor Plate Spacer Kit is engineered as a supporting component within TCI's comprehensive converter lineup, offering a solution for builders who need precise geometry control in competition or heavily modified street applications where factory tolerances no longer apply.
