Built for the toughest towing jobs, the heavy duty CURT Helux gooseneck pin box combines strength with sophisticated shock absorption. The gooseneck design replaces your traditional fifth wheel hitch and restores full truck bed utility for tools and cargo. Proprietary coil and shock technology reduces impact and vibration, keeping your rig stable mile after mile.

This commercial-grade variant stands up to demanding conditions while maintaining passenger and pet comfort through advanced coil spring suspension. The steel construction with black powder coating protects against the elements, and the simple bolt-on installation means you can start towing immediately without any adjustment period.
