Waltco 70093640 WLT Liftgate Solenoid, 4 Pole 12V

The Waltco 70093640 WLT Liftgate Solenoid, 4 Pole 12V is a genuine OEM replacement solenoid designed for reliable high-current switching in Waltco liftgate electrical systems. This 4-post, 12-volt DC solenoid acts as the main power relay, delivering battery voltage to the liftgate motor or hydraulic pump when the control switch is activated.

Built to Waltco’s exact specifications, the 70093640 solenoid handles the heavy amperage demands of liftgate operation while withstanding vibration, heat, moisture, and dust common in South Texas commercial use. A failing solenoid can cause intermittent power loss, slow operation, or complete liftgate failure. Replacing it with this genuine 4-pole unit quickly restores full, responsive performance.

This solenoid is commonly used across many Waltco models including WDV, WDVBG, and other cantilever and rail-style liftgates found on box trucks, flatbeds, and service vehicles throughout the San Antonio area.
