Originally used in Shelby Mustangs and other high-performance vehicles, the RTS “C” Ratio Servo Kit delivers significantly improved holding power, resulting in cleaner and firmer 1-2 and 2-3 shifts. Precision-machined from 6061-T6 billet aluminium, this servo features high quality PTFE lip seals on the piston to ensure superior sealing across a wide range of fluid pressures.

As the largest servo in the C4 family, it’s suitable for all high performance C4, C5, C9, and C10 applications. To address worn cases, the servo pin is equipped with two PTFE sealing rings, maintaining hydraulic integrity even in less-than-perfect housings. Cleaning up a 2-3 shift flare has never been easier.

For those seeking a slightly less aggressive setup, the RTS-SERV2C4 “H” Code Version is also available, offering reduced band apply pressure.
