Tomioka Racing 4.0 Final Drive Gear Set for Mitsubishi Evo 7/8/9 (5-Speed)

Unlock more usable performance from your Mitsubishi Lancer Evolution with the Tomioka Racing 4.0 Final Drive Gear Set. Designed specifically for the Evo 7, Evo 8, and Evo 9 5-speed manual transmission, this 4.0 final drive ratio is the ideal upgrade for high-power street and track builds that have outgrown the factory gearing.

The OEM Evo 8 / Evo 9 final drive is short, which means you are constantly shifting and running out of revs in each gear as power levels go up. By moving to a 4.0 final drive, you get taller overall gearing that keeps the car in each gear longer, improves traction in the lower gears, and drops cruising RPM on the highway. The result is a more flexible, faster Evo that can make the most of a wide powerband.

Why choose a 4.0 final drive for your Evo 8 / Evo 9?

  • Taller gearing for high-power builds – Helps your Evo 7/8/9 stay in boost longer and reduces the need for constant shifting.
  • Improved traction – A slightly taller Evo 8/Evo 9 final drive ratio tames wheelspin in first and second gear, especially on big-turbo cars.
  • Lower cruising RPM – More comfortable highway driving and less stress on the engine at constant speeds.
  • Better use of your powerband – Perfect for cars that see roll racing, time attack, and road course use.

Motorsport-grade construction

This Evo 8/Evo 9 5-speed final drive gear set is manufactured by a specialist motorsport gear factory that also produces performance differentials and gear sets for well-known brands. The gears are made from high-strength forged steel and precision-machined to exact tolerances for durability under hard launches, aggressive shifting, and continuous track use.

  • High-strength forged steel – Built to handle serious power and abuse.
  • Precision-machined tooth profile – Reduces friction and drivetrain loss while maintaining strength.
  • OEM-style fitment – Designed as a direct replacement for the factory Evo 7/8/9 5-speed ring and pinion.

Direct bolt-in for Evo 7/8/9 5-speed

This Tomioka Racing 4.0 final drive kit is engineered as a bolt-in solution for the Evo 7, Evo 8, and Evo 9 5-speed manual transmission. No custom machining is required when installed by a competent transmission builder.

  • Vehicle: Mitsubishi Lancer Evolution VII / VIII / IX
  • Transmission: 5-speed manual
  • Final Drive Ratio: 4.00
  • Application: Street, track, time attack, roll racing

What’s included

  • 4.0 final drive ring gear
  • Matching final drive pinion/output shaft
  • Application-specific gear set for Evo 7/8/9 5-speed transmission

For best results, we recommend pairing this 4.0 final drive gear set with an upgraded rear helical LSD and a quality performance clutch. Together, they transform how your Evo puts power to the ground and improve consistency on both street and track.
