Reinforced 3/4/5‑Speed Gear Set engineered exclusively for Honda Fit GK5. It precisely solves the pain points of power drop‑off and insufficient strength on the stock mid‑to‑high‑speed gears.
One‑piece forged chrome‑molybdenum alloy steel construction offers excellent impact resistance and wear resistance, easily coping with high‑RPM track conditions and turbo power upgrades.
Featuring optimized close‑ratio gearing to minimize RPM drop between gears. The engine remains within its optimal power band after upshifting for more direct acceleration response upon corner exit.
Direct drop‑in replacement design, compatible with OEM synchronizers and transmission housing. No major modifications are needed. It is a cost‑effective transmission upgrade option for GK5, capable for both daily street commuting and track lap racing.
