Curt 5th wheel rails are industry-standard, meaning the attachment points for the 5th wheel hitch are standardized to accept any hitch with industry-standard legs. This includes virtually all Curt 5th wheels and many competitor models.
Curt's 5th wheel rails are constructed from high-strength steel and tested according to SAE J2638 specs. They are designed to pair with Curt custom under-bed brackets to provide a solid foundation to mount your 5th wheel hitch (custom brackets sold separately).
