Vacuum Switch - Aftermarket (Decoupler & Locker)

These new, higher-quality, and lower cost manually-controlled GoWesty pneumatic valves are a great way to save a few bucks on your Syncro locker/decoupler console. This switch even comes with an adaptor shaft that allows you to use an OEM knob (if you have an extra).

Fits: All 1986-91 4WD Syncro Vanagon models

Note: This product is shipped with everything you need to replace an original OEM VW switch at the dash, but does not include the white vacuum tubing that connects the switch itself to the differential lock, or decoupler. If you need the tubing, you can purchase our complete Knob & Switch Kit.
