Precision CNC machined from high quality high tensile strength USA solid billet steel, it far surpasses the strength of the factory stamped plate. As the factory plate wears out, it fails to properly position the main shaft, resulting in very poor shifting performance and increased thrust wear throughout the entire transmission. This Heavy Duty cover plate is incredibly rigid and is able to hold the main shaft in place, even with very high horsepower engines.
Fits R-Series transmissions (R150, R150F, R151F, R154, etc). Includes a set of four Grade-6 JIS bolts which are stronger (tensil and sheer) than the stock Toyota cover plate bolts.
