The AP Racing Quick Lift Jack Connector Valve provides a user interface between the vehicle air jack system and external air supply via the pit crew. The connector valve has been designed to fix into the vehicle side of the Fast Air Jack system providing the connection point to the pit lane side lance (available separately). The valve contains a male end JIC fitting which can be attached to a hardline plumbing kit, which then links to the fast air jacks for rapid vehicle lifting and lowering.The connector valve features an operating sleeve, which allows the height of the vehicle to be adjusted once the system is full/at full height. The sleeve should simply be adjusted and the system vented until the required height is reached.A simpler valve is also available which does not contain a valve. As there is no valve, the air will be released as soon as the lance is removed.
