Proposition 65: This product may contain chemicals known to the state of California to cause cancer, birth defects, or other reproductive harm.

The original locker/decoupler vacuum valve switches are expensive and hard to find! When the time comes, update your system with these new, high quality, and lower cost manually-controlled GoWesty pneumatic valves. This switch even comes with an adaptor shaft that allows you to use an OEM knob (if you have an extra), or you can switch over to our aftermarket knob so they all match.

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.
