Description
Genuine Bendix K073055 SMS-9700 air solenoid valve assembly — a 12V normally-closed manifold-stack solenoid used to control air flow in HD truck cab and chassis air systems (cab leveling, air-ride seats, lift / pusher axle controls, and auxiliary on-board air circuits). This variant ships without a supply fitting and uses a 1/4″ push-to-connect (PTC) port with a Metri-Pack 150 sealed two-pin connector.

Applications
The SMS-9700 solenoid is used across HD truck OEM platforms for low-current 12V air control, including:
- Cab and air-ride seat leveling circuits
- Lift / pusher axle raise-lower controls
- Sleeper and auxiliary on-board air control modules
- Transmission and PTO auxiliary air solenoid stacks
Representative chassis families include Class 7–8 highway tractors and vocational trucks (Freightliner, International / Navistar, Kenworth, Mack, Peterbilt, Volvo, Western Star) specifying SMS-9700 stack solenoids.
Confirm system voltage (12V vs 24V), N.C. vs N.O. configuration, and whether your manifold position requires the supply-fitting variant before ordering.
