Product Details

The Cusco 438 028 AX2 is a close ratio transmission gear kit engineered specifically for the Mazda Demio DE5FS with ZY-VE engine (2007+). This performance upgrade replaces the stock transmission gears with a tighter gear ratio spread, optimizing acceleration and power delivery throughout the rev range.

Key Features:

  • High-strength construction using SCr/SCM and SNCM metal alloys for enhanced durability
  • Optimized close ratio gear set for improved performance: 1st: 2.538, 2nd: 1.875, 3rd: 1.526, 4th: 1.208, 5th: 0.963
  • Significantly closer ratios compared to OEM gears (OEM: 3.416, 1.842, 1.290, 0.972, 0.775)
  • Includes strengthened main shaft for increased reliability
  • Compatible with standard final drive ratio

This transmission gear kit is designed for enthusiasts seeking better acceleration response and more efficient power transfer. The closer gear ratios reduce the RPM drop between shifts, keeping the engine in its optimal power band. Professional installation is strongly recommended due to the technical complexity of transmission work.
