The Mack ALK3 Airline Kit replaces the three 3/16-inch airlines and all fittings that run between the slave valve on top of the transmission and the shift knob on Mack transmissions equipped with 2- or 3-airline shift knobs. The kit includes 10-foot red, black, and blue 3/16-inch color-coded airlines, two 90-degree swivel push-in style fittings, one straight push-in fitting, and nine colored pull ties. The 90-degree swivel elbows allow installation without removing the slave valve. Push-in installation avoids over-tightening the original fittings, which is a known cause of synchronizer damage. Call us to confirm proper fit for your specific Mack transmission application.

The ALK3 kit is designed to replace the airlines and fittings on the slave valve and the three 3/16-inch air lines running between the slave valve on top of the transmission and the shift knob. Over-tightening of the original fittings on the slave valve is a known cause of synchronizer damage. The push-in fitting design in this kit eliminates that risk. The included 90-degree swivel elbows mean the slave valve does not need to be removed to complete the installation.
