Extra Long Pin, with Seals

View Instructions

The Sonnax 4L60 / 4L60-E servo pin is longer than the longest OE pin. 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.
