Description

Overview

Jaw and Pin Kit Holland Pro Hitch 351 342 331 restores fifth wheel locking control and safer coupling checks. It targets wear in the jaw, pin, and yoke area where load and vibration concentrate. As a result, it helps return the hitch to a more consistent lock-up feel after inspection.

Features

This kit replaces worn locking parts so the kingpin seats and clamps correctly. The lubrication points support routine greasing during scheduled servicing, and new jaw and pin components can reduce free play that accelerates wear. It also suits common Pro Hitch series applications for fleet standardisation.

• Service replacement set for the jaw and pin locking assembly
• Includes yoke-related components to restore correct movement
• Supports inspection and preventative maintenance routines
• Helps maintain secure coupling under load

Compatibility and Fitment

Jaw and Pin Kit Holland Pro Hitch 351 342 331 suits Holland Pro Hitch 351, 342, and 331 series couplings. Confirm the hitch series and release style before ordering. Inspect the yoke and jaw area for distortion, then replace parts as a set if wear appears uneven.

Compliance and Safety

Fifth wheel locking parts affect coupling safety, so a qualified technician should fit the kit and complete functional checks. Test the coupling with a correctly sized kingpin after installation, then confirm secondary lock action. Follow current manufacturer maintenance guidance and grease intervals for the model.

Trailer Applications

Workshops use this kit during fifth wheel servicing on prime mover and semi-trailer combinations. Fleet operators also fit it when coupling feels tight, release feels inconsistent, or jaw faces show rounding. It suits heavy trailer operations with frequent coupling cycles.
