Tired of fighting trailer sway or worrying about hitch failures when hauling heavy loads? Standard pin boxes often lack the precision engineering needed for demanding RV towing conditions. The Curt Helux Coil-Spring Gooseneck Pin Box solves these problems with its robust 20,000 lbs capacity and advanced shock-absorbing coil spring system.

Features

• 20,000 lbs gross trailer weight rating – Handles the heaviest fifth-wheel configurations
• 3,200 lbs pin weight capacity – Distributes load evenly for safer towing
• Coil-spring suspension absorbs road shocks while maintaining steering precision
• Helux™ friction technology reduces chucking and sway by 40% vs standard designs
• Forged steel construction with zinc plating resists corrosion from road salts
• Direct bolt-on replacement for most gooseneck trailers with 2.5" kingpin

Engineered for professional haulers and serious RVers, the Helux pin box transforms your towing experience. The proprietary coil spring system works in tandem with Curt's friction technology to eliminate the jerky movements that cause driver fatigue. Unlike rubber-based systems that degrade over time, the Helux maintains consistent performance trip after trip.

This pin box is the solution for owners upgrading from bumper pulls or experiencing instability with their current setup. The 20K rating means you'll never question whether your hitch can handle the load—even when navigating steep grades or crosswinds.
