The original locker/decoupler valves are expensive and hard to find! When the time comes, update your system with these new, high quality, AND lower cost manually-controlled pneumatic valves.
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-KIT.
Fits: All 1986-91 4WD Syncro Vanagon models
