⭐ 2024 SEMA Show Award Winner — "Best New Exterior Accessory"

Standout industry credential: the CURT Helux Coil-Spring 5th Wheel Pin Box won "Best New Exterior Accessory" at the 2024 SEMA Show in Las Vegas — one of the biggest stages in the automotive aftermarket. The award recognized Helux for its groundbreaking impact on RV ride comfort and durability, setting a new standard in towing technology.

⭐ 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 over years of towing
• Less shifting of cargo and gear during transit — protects belongings
• Smoother, more controlled ride — noticeable for passengers and pets
• Reduced stress at the coupling point — where hitch forces concentrate

⭐ Proprietary Coil-Spring & Shock Absorber Technology

Standout design vs traditional fixed pin boxes and airbag systems:

• Automotive-grade coil spring — delivers a 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

Standout convenience vs airbag-style pin boxes:

• No air pressure to check — no compressor, no gauges, no leaks to chase
• No components to adjust — dial in once, tow forever
• No break-in period required — full performance from day one
• No airbags that can fail — coil spring outperforms and outlasts air systems
• Just install and go

⭐ Pin Weight Selection — Sized for Your 5th Wheel

Critical sizing information: The right Helux pin box depends on your 5th wheel's loaded pin weight. This model (2024044569) is optimized for:

• Optimal loaded pin weight range: 2,723-3,165 lb
• Minimum pin weight (unloaded — empty tanks, no cargo): 1,610 lb
• Maximum pin weight (fully loaded): 3,500 lb
• Gross trailer weight capacity: Up to 18,000 lb

Prefer Gooseneck Instead?

The Helux is also available in a gooseneck configuration — meaningful for buyers who want to free up truck bed space vs traditional 5th wheel setups. Gooseneck Helux uses an auto-latching coupler that connects to any standard 2-5/16" gooseneck ball. All gooseneck variants are rated to 20,000 lb capacity:

• Helux Gooseneck 2,350 lb Max Pin Wt (2024044575)
• Helux Gooseneck 2,700 lb Max Pin Wt (2024044574)
• Helux Gooseneck 3,200 lb Max Pin Wt (2024044576)
• Helux Gooseneck 3,900 lb Max Pin Wt (2024044577)
• Helux Gooseneck 4,300 lb Max Pin Wt (2024044578)
• Helux Gooseneck 5,000 lb Max Pin Wt (2024044579)

⭐ Approved for All Lippert RV Frames — Will NOT Void Warranty

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. If your RV was built with a Lippert frame (the vast majority of North American RVs are), you can upgrade to Helux with confidence.

⭐ Direct Rhino Box Replacement — Bolt-On Upgrade

Standout installation benefit: compatible with the Rhino Box bolt-mounting pattern — straightforward direct replacement for buyers currently running a Rhino Box or comparable pin box.

Rugged Construction & Safety Certification

• Premium steel construction
• Black powder coat finish — resists wear, corrosion, and long-term appearance degradation
• Fully tested to SAE J2638 safety standards
• Made in USA with global materials

⚠️ Purchase Verification Required

Important buyer note: CURT requires purchase verification for Helux pin boxes to ensure correct sizing. Refer to the CURT instruction sheet for the proper pin weight measuring process before finalizing your order. The best way to determine actual pin weight is to weigh your fully-loaded 5th wheel at a certified scale (CAT Scale, truck stop scale, etc.) with everything you'd normally have on board when traveling — including ATVs, golf carts, motorcycles, snowmobiles, and full tanks.

⚠️ 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 5th wheel 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].
