Compatibility and Fitment

Check the fifth wheel model and existing locking bar before fitting. Also inspect the lock jaw, pivot, spring, adjusting screw and operating handle because wear in connected parts can affect how the lock closes behind the kingpin.

Related Parts

Check the related service parts below against the fifth wheel setup before ordering.

Compliance and Safety

Inspect the locking mechanism before returning the vehicle to work. The handle must retract fully, the safety latch must sit correctly and the lock bar must travel across the fifth wheel throat behind the lock jaw. If any connected part binds or shows wear, replace the affected component before coupling.

Trailer Applications

Workshops use this JOST fifth wheel locking bar during turntable servicing on prime movers, converter dollies and heavy trailer coupling setups. It suits repairs where the locking mechanism needs a parts-matched lock bar rather than a complete fifth wheel replacement.
