- Twelve-inch center-to-center mounting to provide a direct-fit replacement for modern Jost slider assemblies

Jost Fifth Wheel Trailer Hitch Air Cylinder
The Jost Fifth Wheel Trailer Hitch Air Cylinder is a 12-inch pneumatic actuator designed specifically to operate the locking plungers on JSK37 series sliding fifth wheel assemblies. Engineered as the "New Style" replacement, the Jost SK75015-03 features a corrosion-proof composite body and an external return spring that ensures locking pins fully re-engage when air pressure is released. This cylinder provides the high-force stroke required to move heavy-duty slider plates under load, allowing drivers to reposition the trailer hitch from the cab without manually pulling the lever. Its lightweight construction and 0.408-inch diameter rod are designed to withstand the harsh environment of the tractor frame rail, making it a critical component for maintaining weight distribution and axle compliance.
