RTS’ “H” Ratio Servo Kit offers a slightly less aggressive setup than our “C” code version, while still delivering increased holding power for cleaner, firmer 1-2 and 2-3 shifts, giving you a more street-friendly shifting feel. Machined from high-quality 6061-T6 billet aluminium, this servo features high quality PTFE lip seals on the piston, ensuring excellent sealing performance across a wide range of fluid pressures.

As the second-largest servo in the C4 family, it’s compatible with all performance C4, C5, C9, and C10 applications. To maintain hydraulic integrity even in worn cases, the servo pin includes two PTFE sealing rings. Eliminating a 2-3 shift flare is simple and effective with this upgrade.
