Tired of white-knuckle towing experiences with your heavy trailer? Standard pin boxes often transmit every bump directly to your truck, causing fatigue and reducing control. The Curt™ Helux Coil-Spring Gooseneck Pin Box solves this with its innovative shock-absorbing design that maintains positive trailer connection while dampening road vibrations.
Features
- 20,000 lbs gross trailer weight rating - Handles even the heaviest gooseneck trailers
- 2,350 lbs pin weight capacity - Distributes tongue load evenly for stable towing
- Coil-spring suspension system - Absorbs 40% more road shock than rigid designs
- 2-5/16" forged ball socket - Precision-machined for secure connection
- Dual-stage latching mechanism - Positive engagement with visual and audible confirmation
- Galvanized steel construction - Resists corrosion from road salt and moisture
Unlike basic pin boxes that transfer every bump to your tow vehicle, the Helux's progressive-rate coil springs act as a buffer between trailer and truck. This means less driver fatigue on long hauls and reduced wear on both your RV and tow vehicle components.
The patent-pending latching system provides unmatched security with dual-stage engagement. You'll both hear and feel the positive connection, eliminating guesswork when hitching up. The integrated breakaway switch wiring keeps your trailer brakes functioning properly in emergencies.
