The award recognized Helux for its groundbreaking impact on RV ride comfort and durability, setting a new standard in towing technology.

⭐ Gooseneck Configuration — Free Up Your Truck Bed

Standout benefit vs traditional 5th wheel pin box setups: the gooseneck configuration allows full use of your truck bed for tools, gear, ATVs, cargo, or whatever else the road demands. Meaningful for:

• Work trucks that need bed cargo space even while towing
• Overlanders and outdoor enthusiasts hauling gear alongside the RV
• Recreational users who want maximum utility from their truck

Uses a standard 2-5/16" gooseneck ball connection — the same ball you'd use for gooseneck horse trailers or other gooseneck loads.

⭐ 30% Force Reduction on RV Frame & Body — Standout Feature

Standout engineering benefit vs traditional and airbag-style pin boxes: reduces force transferred into the RV frame and body by up to 30%. Meaningful long-term benefits:

• Reduced wear and tear on RV frame, walls, cabinets, and interior components
• Extended structural life of the trailer
• Less shifting of cargo and gear during transit
• Smoother, more controlled ride for passengers and pets
• Reduced stress at the coupling point

⭐ Proprietary Coil-Spring & Shock Absorber Technology

Standout design vs traditional fixed pin boxes and airbag systems:

• Automotive-grade coil spring — forgiving, consistent ride quality
• Integrated shock absorber — dampens chucking, jarring, and vibration
• Minimizes stress at the coupling point
• Especially noticeable comfort improvement for passengers, pets, and mounted cargo

⭐ Virtually Maintenance-Free — No Airbags, No Adjustments

• No air pressure to check
• No components to adjust
• No break-in period — full performance from day one
• Coil spring outperforms and outlasts air systems

⭐ Auto-Latching Coupler — Streamlined Hookup

Standout convenience feature: auto-latching coupler connects quickly and securely to any standard 2-5/16" gooseneck ball. Meaningful for a faster, safer hookup process — get on the road faster.

⭐ Pin Weight Selection — Sized for Your Trailer

Critical sizing information: The right Helux pin box depends on your trailer's loaded pin weight. This model (2024044574) is optimized for:

• Minimum pin weight (unloaded): 1,550 lb
• Maximum pin weight (loaded): 2,700 lb

Meaningful compatibility credential: the CURT Helux pin box is fully approved for use on all Lippert RV frames and will not void your Lippert frame warranty.

Rugged Construction & Safety Certification

• Premium steel construction
• Black powder coat finish — resists wear and corrosion
• Fully tested to SAE J2638 safety standards

⚠️ Purchase Verification Required

Important buyer note: CURT requires purchase verification for Helux pin boxes to ensure correct sizing. Weigh your fully-loaded trailer at a certified scale with everything you'd normally have on board when traveling. Refer to the CURT instruction sheet for the proper pin weight measuring process.

⚠️ Professional Installation Required

The pin box assembly weighs several hundred pounds. Installation and removal requires a minimum of two people. A forklift may be used to lift the pin box into position. The trailer should always be towed while level — adjustment of pin box mounting height, tow vehicle height, or suspension may be necessary to achieve a level towing condition. Installation should be performed by a qualified RV service technician unless you have prior experience with pin box replacement and the appropriate equipment.

Limited Lifetime Warranty

CURT backs the Helux pin box with a limited lifetime warranty (one-year finish, one-year parts).

⚠️ Freight Shipping — No Returns Due to Product Size

Important buyer note: this item ships freight due to its size and weight, and is not eligible for return. Please carefully verify all specifications, compatibility, and fitment before ordering — including product-specific verification points.
