The CURT CrossWing — Lightweight 5th Wheel Hitch (20K)

The CURT CrossWing is engineered as a lightweight yet robust alternative to traditional 5th wheel hitches — meaningful for buyers who want easier install/removal, one-person handling, and modern coupling technology. Meaningful highlights:

• ⭐ 65% lighter than traditional 5th wheel hitches — main body weighs only 60-70 lb (compared to 150+ lb for premium 20K hitches)
• ⭐ 20,000 lb gross trailer weight (GTW) capacity — full 20K rating despite the lighter weight
• ⭐ Patent-pending ShockDrop technology — integrated rubber isolator reduces jerking and jarring during towing
• ⭐ Multi-axis head articulation — fore, aft, and lateral head movement for comfortable towing on rugged roads
• ⭐ Unique visible contact surface — eliminates coupling guesswork; other lightweight 5th wheels have hidden striking surfaces that require multiple attempts
• ⭐ Head channel guides kingpin into place — easier hookup, less lining-up hassle
• ⭐ ONE-person install — 3-bolt assembly, ready out of box, no drilling
• ⭐ Strategic grip points for ergonomic lifting
• ⭐ Easy-to-reach release handle
• Three-point height adjustment — 17-1/2" to 21-1/2"
• High-grade steel construction (not aluminum) — carbide textured black powder coating for long-lasting rust resistance
• Lippert trailer chassis approved — will not void Lippert frame warranty
• SAE J2638 safety standard tested
• Backed by CURT's limited lifetime warranty (one-year finish, one-year parts)

Configuration Details

Configuration: Industry-Standard Rails

Drops into any industry-standard 5th wheel base rails and secures with included pins

All CrossWing Hitch Configurations

CURT offers CrossWing in three mounting configurations:

• #16600 — Industry-Standard Rails Mount ($749.95)
• #16602 — Single-Point Gooseneck ($824.95)
• #16051 — Gooseneck + Bed Protectors ($997.95)

⚠️ Pin Box Compatibility — RIGID MOUNT ONLY

CrossWing is compatible with rigid-mount pin boxes only. DO NOT use CrossWing with articulating pin boxes, including:

• Roto Flex
• Flex Air
• Air Ride
• Helux (CURT's own coil-spring pin box line)
• Other articulating/cushioning pin box designs

The CrossWing's ShockDrop technology already provides articulation and cushioning at the hitch. Combining it with an articulating pin box creates unsafe double-articulation. If you have an articulating pin box, use a traditional rigid-mount 5th wheel hitch (A-Series, E-Series, PowerRide) instead.

Although CrossWing is engineered for one-person installation, first-time installers should reference the CURT installation instructions carefully. Installation should be performed by a qualified installer if unfamiliar with 5th wheel hitch service.
