Sonnax C Ratio Servo Kits

Sonnax C ratio servo kits offer greater holding power, giving cleaner, firmer 1-2 and 2-3 shifts. They are machined from 6061 aluminum billet and feature lip seals on the piston for superior sealing over a wide range of fluid pressure. The C ratio servos are the largest in the C4 family, and will work equally well in performance C5 applications. The pins incorporate two PTFE sealing rings to insure the hydraulic integrity of the pins in worn cases. Experience firmer shifts with Sonnax C ratio servo kits.
