✓ Authorized Lippert Dealer✓ OEM Authentic Curt ProductPremium coil-spring pin box for smooth, stable 5th wheel towing
Nothing ruins a road trip faster than a fishtailing trailer or bone-jarring bumps from an inadequate pin box. Standard rubber-block designs wear out quickly and transmit every road imperfection into your RV’s frame. The Curt Helux Coil-Spring Pin Box solves these problems with its advanced suspension system engineered for heavy-duty towing applications.
Features
- 18,000 lbs. gross trailer weight rating – Handles even large fifth wheel trailers with confidence
- 2,600 lbs. maximum pin weight capacity – Supports heavy front-end loads without compromising stability
- Coil-spring suspension system – Absorbs road shocks better than rubber-block designs for a smoother ride
- Precision-machined kingpin – 2-5/16″ diameter meets SAE J133 specifications for reliable hitch engagement
- Durable steel construction – Powder-coated finish resists corrosion from road salt and weather
- Maintenance-free design – No greasing required for long-term reliable performance
Engineered for RVers who demand the best towing experience, the Curt Helux pin box transforms how your fifth wheel handles on the road. The progressive-rate coil springs actively dampen trailer oscillations that cause sway, while simultaneously isolating your RV from harsh road impacts. This means less driver fatigue on long hauls and reduced stress on your trailer’s frame.
Unlike basic pin boxes that bottom out on rough roads, the Helux’s suspension system provides consistent performance whether you’re navigating city streets or mountain passes. The kingpin’s precise machining ensures positive engagement with your hitch every time, eliminating the worrying “clunks” and play of worn components.
