CURT Helux 5th Wheel Pin Box

Helux™ 5th Wheel Pin Box

The Most Advanced Pin Box in the Industry

Helux is an innovative pin box design that is aimed at ultimate user comfort and towing control. It is built around our proprietary coil-spring technology that absorbs chucking, jerking, jarring, and vibrations at the truck-trailer coupling point.

Helux has been fully tested to J2638 specifications and is approved for use on all Lippert trailer frames.

Available on select 2025 Alliance Paradigm, Alliance Valor, Brinkley Model Z, Keystone Arcadia, and Keystone Cougar models.
