Tired of unpredictable trailer sway or jerky rides that stress your RV's frame? Standard pin boxes often transmit road shocks directly to your rig, causing premature wear and driver fatigue. Curt engineered the Helux Coil-Spring Pin Box to absorb vertical impacts while maintaining precise lateral control—giving you smoother towing and longer-lasting components.

Features

• 24,000 lbs. capacity handles even the heaviest fifth-wheel trailers
• 5,400 lbs. pin weight rating distributes load evenly across your RV chassis
• Coil-spring suspension reduces chucking by 40% compared to rigid designs
• Precision-machined Lippert mounting points ensure bolt-on compatibility
• Maintenance-free pivot bushings eliminate greasing for hassle-free ownership
• Powder-coated finish resists corrosion from road salt and moisture

Unlike basic pin boxes that transfer every bump to your cab, the Helux's dual-stage coil springs progressively absorb energy. This means fewer white-knuckle moments when hitting potholes or uneven roads. The system's balanced damping also prevents trailer oscillations that can lead to dangerous sway situations at highway speeds.

Engineered specifically for Lippert-equipped RVs, this Curt pin box maintains OEM-grade fitment while upgrading your towing dynamics. The forged steel construction meets SAE J2638 standards for strength—critical when carrying expensive rigs through mountain passes or cross-country hauls.
