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 Chrome-moly 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.

• O-ring seal between pin and 2nd gear piston
• Two PTFE rings seal pinto bore
