Looking For Crossbar System To Go On Roll N Lock XT Tonneau Cover On 2024 GMC Sierra 1500 Crew Cab

Updated 05/19/2025 | Published 05/15/2025

Question:

What is the most versatile truck cross bar system that fits the T slots on my Roll N Lock XT manual sliding tonneau cover. Truck is a 2024 GMC Sierra 1500 crew cab . Would like a black finish, low profile that will allow me to mount Yakima, Thule, etc bike, kayak, cargo box and maybe more accessories ? In addition is the a simple T rail mount that will allow me multi cross bar options ? Thank you

Hello Phil, thanks for reaching out. The Roll N Lock XT cover uses a pretty standard T-track. What I recommend for a crossbar system is the following:

- Rhino-Rack Vortex Crossbars for Retrax XR and Mountain Top EVO-M Tonneau Covers - Black - 71" L # RRVA180B-RRRLT600

This is a full crossbar system so you get your 71" Aero crossbars, towers and T-track installation hardware. The crossbars have a top channel so you can use virtually any channel mount accessory. Also the aero crossbars are standard, so they will work with pretty much any clamp-on accessory like a kayak carrier or cargo box. This includes accessories from Thule, Yakima, Rhino Rack and more - they all work with aero crossbars.

The video I linked below will show you an example of installation.

What kind of cargo are you looking to carry? We have solutions for pretty much everything so let me know and I am happy to make a recommendation.

Hi Jesse Thank you for this great info ! I’m sure it will help others. There is much mentioned about the Retrax system good to know it’s the same for. One more question. Can I use the 65 in bar instead of the 71. I don’t want it hanging out. Will to give up some space. I received a Rhino Rack from a friend and will work off of that. Eventually 2 stand up bike racks and some sort of storage box (es). I am hoping I can mount a ladder rack to the platform for sort trip uses if not look into that separately Thanks Jesse

@Phil You can do a shorter bar as long as it spans the bed rails. I was not able to find the exact bed rail width listed online but you should easily be able to measure and determine if the 65" will fit. You should be good but please verify. The Thule ProRide XT # TH598004 is what I recommend for a bike carrier. The following link will show you our full selection of roof boxes. Please let me know if there is anything else I can do to help.
