Why Choose the Synchrotech 2.13 2nd Gear?
OEM 2nd gears often fall short in performance setups. The Synchrotech Pro Series 2.13 ratio offers a stronger, better-matched 2nd gear that keeps your engine in its powerband, especially between 1st and 2nd gear during fast shifts. This is a must-have upgrade for K-series race cars, turbo builds, and track-focused setups.
