Yes, these brackets are compatible with the 2025 GMC 1500 new body style (does not work with GM auto-leveling feature) with the Pullrite Super-Glide ISR Series hitches.
However with a 5.5FT bed, Pullrite recommends their 3100 series hitch, which require a different set of brackets and rails (none available for your truck).
The SuperGlides require a capture plate, we'd just need to know what model of pin box you have on your 5th wheel trailer, if unsure, then we'd just require some measurements. You may contact us at info@hitchweb.com or call 800-300-4067 x2.
