The servo pin in Sonnax servo pin kit 77787-02K is longer than the longest OE pin in GM 4L60, 4L60-E, 4L65-E and 4L70-E applications. The extra length simplifies adjustment, eliminating the need for adding length to the pin. Made from chromoly steel, it is durable enough for high performance applications as well as stock replacement. Dual PTFE seals have been added to improve sealing in the case bore and an O-ring has been added to improve sealing between the pin and the 2nd Gear servo. The Sonnax servo pin is fully compatible with OE and aftermarket servos.
