The USA Standard Gear ZMMUNWT297-16 is a precision-engineered Muncie M21 input gear engineered for high-performance applications. This critical transmission component features a 26-tooth count and a 10-spline design, specifically intended for Muncie M21 close-ratio transmissions that utilize a 2.20 gear ratio. Constructed from durable high-strength steel, this gear is built to ensure reliability and longevity even under demanding operational conditions. Key specifications for this Muncie M21 input gear include a 26-tooth count, a 10-spline count, a 2.20 gear ratio, and a 3.15" outside diameter. The high-strength steel construction ensures robustness and resistance to wear. Fitment is confirmed for a range of classic vehicles equipped with the Muncie M21 transmission, such as the Buick Century (1973-1974), Buick Electra (1967), Buick Gran Sport (1967), Chevrolet Camaro (1967-1974), Chevrolet Corvette (1966-1974), Oldsmobile 442 (1966-1971), and Pontiac GTO (1966-1967 & 1970-1971). Installation notes recommend ensuring all components are clean and free from debris, with proper alignment being crucial for optimal performance. Professional mechanic consultation is advised for those unfamiliar with transmission assembly.
