Designed for demanding motorsport and high-torque applications, this Close-Ratio Transmission Gear Set minimizes RPM drops between shifts to keep your engine consistently in its optimal powerband. Machined from high-tensile forged alloy steel, this comprehensive kit includes precision-cut helical gears, a splined main shaft, synchro hubs, and sleeve assemblies built to withstand extreme mechanical stress.
Optimized Close-Ratio Gearing: Keeps engine RPM high during gear changes, delivering faster acceleration, sharper throttle response, and seamless power delivery.
High-Tensile Forged Steel Construction: Heat-treated and shot-peened for maximum core strength, surface hardness, and fatigue resistance under high load.
Precision Helical Tooth Design: CNC-ground teeth ensure smooth mesh engagement, high load capacity, and quiet operation compared to straight-cut options.
Heavy-Duty Splined Main Shaft: Engineered with precision-cut splines for exact fitment, optimal torque transfer, and reduced backlash.
Complete Performance Assembly: Includes matching gears, synchro assemblies, and shaft components for a complete transmission refresh or upgrade.
