Features
Integrated T-Slot Rack Rails The full-length T-slot rails are what make the X4ts rack-ready. They accept crossbars, bike and kayak carriers, cargo baskets, and roof-top tents so you can carry gear over the closed cover while the bed stays locked.
Direct Replacement Fit Matched to the X4ts cover for the 2019-2026 Chevrolet Silverado & GMC Sierra 1500, these rails clamp to the same factory bed rails as the original set for a direct, no-drill replacement.
No-Drill Clamp-On Install The rails clamp to your factory bed rails with the included hardware, so there is no cutting, trimming, or drilling. Basic hand tools and the Revolver install sheet are all you need.

About BAK Industries
BAK Industries has engineered premium truck bed covers in the USA for decades and is a flagship tonneau brand of RealTruck, one of the largest truck-accessory manufacturers in North America. Its hard-folding BAKFlip and retractable Revolver lines set the benchmark for the category, pairing heavy-duty aluminum construction with a low-profile, weathertight design.
Every BAK cover is built for real-world truck use: no-drill, clamp-on installation that mounts in about 30 minutes, full bed access when folded or rolled back, and reinforced latching that keeps cargo secure and dry. The lineup runs from the value-focused BAKFlip MX4 and G2, to the flagship FRP-panel F1 and FiberMax, to the industrial Revolver X2 and X4s roll-ups, covering nearly every popular truck and bed length.
Backed by US-based product support and a multi-year manufacturer warranty, a BAK cover is a buy-it-once upgrade that protects tools, cargo, and gear while giving a truck a cleaner, more finished look.

Frequently Asked Questions
Straight answers on specs, fit and support
What exactly comes in this kit?
This is a rails-only kit: the pair of BAK Revolver X4ts T-slot rack rails and their clamp hardware for the 2019-2026 Chevrolet Silverado & GMC Sierra 1500 5'8" bed. It does not include the roll-up cover. If you need the full cover and rails, order the complete X4ts cover instead.
Will these rails fit my X4ts cover?
Yes, these are the matched T-slot rails for the X4ts cover part 80130RK, which fits the same 2019-2026 Chevrolet Silverado & GMC Sierra 1500. They clamp to the factory bed rails exactly like the original set.
Why would I buy rails separately?
Two reasons: to replace rails that were damaged or lost, or to restore the T-slot rack capability on a cover. The rails are what let you mount crossbars, carriers, and tents over the closed cover.
Do the T-slot rails require drilling?
No. Like the cover, the rails clamp to your factory bed rails with the included hardware, so there is no drilling or cutting. Follow the BAK Revolver install sheet for clamp placement.
What can I mount on the T-slot rails?
The T-slot channel accepts compatible crossbars, bike and kayak carriers, cargo baskets, and roof-top tents. Always stay within the load limits set by your rack or accessory maker, and distribute the weight evenly along both rails.
How long does it take to install the rails?
Most people fit the rails in about 20 to 40 minutes with basic hand tools. Set each rail on the factory bed rail, clamp it, and tighten evenly, then recheck the clamps after your first week of driving.

Look is great. 100 lbs
Look is great. 100 lbs lighter than my 2nd pick. Lid lock and opening are smooth. Only minor knock I give is the the tie down hooks are hard to install - thinking I should have done them before installing.

A must have
I really like this mat. I was apprehensive at first but, the mat does a great job of keeping things from sliding around without having to secure it. perfect fit. But i think i will be adding some short screws to secure the mat to the DECKED system.

I never knew how much I needed this
As with all BAK covers, the quality is amazing. What I didnt fully appreciate until installing was the ease of opening - especially in a lifted truck. No more need to find the right handhold. Just roll it back with a single hand. Its also great to see out of my rear window when fully open - something you lose with the fold back covers. Customer service is awesome. I has an installation question and the representative stayed on the line as I adjusted an alignment to ensure I did it properly.

Better then expected.
Searched for about 6 months to find the tonneau cover. I really wanted the security of a hard top without sticking above the bed rails it checked those boxes. I also did not want to drill my truck bed. The install was super simple my wife and I had it on the truck in about a half an hour.

The toolbox is nice. I
The toolbox is nice. I think Ill get a lot of years of service out of it. I like how the lid opens and the tie downs are a nice touch. It seems to be well built. And tough. Im pleased with my purchase and would buy another one.
