Tonneau covers for the 2019-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 long: what to know first

The long bed is the biggest of the three Silverado 1500 beds, with a floor length of 98.18 in against 79.44 in for the standard bed and 69.92 in for the short bed. Inside width is 71.4 in and wheel well width is 50.63 in. Makers call it an 8ft or 8' bed. Three covers have a part number for it: ACCESS Original 12409, ACCESS LITERIDER 32409 and BAKFlip MX4 GEN 3 BAK-448132. For five others, the Tyger T1, T3 and T4 and the two MOSTPLUS covers, the maker's own list shows no part for this bed. The truck comes in Regular Cab, Double Cab and Crew Cab, with a Multi-Flex tailgate (available), an EZ Lift power lock and release, and a power up/down tailgate (available). The makers list the same covers for the GMC Sierra 1500.

How to choose for this bed

Three covers are left, in two types. Soft roll-up: ACCESS Original (12409) with a 5-year warranty and ACCESS LITERIDER (32409) with a 3-year warranty. Hard quad-fold: BAKFlip MX4 GEN 3 (BAK-448132), also 5 years. That is the whole choice, so the question is roll-up or hard fold. Only BAK publishes a distributed load rating, 400 lb, which makes it the highest load rating listed here. ACCESS publishes no load rating and no cover weight, and BAK gives no cover weight either. MOSTPLUS publishes 350 lb for its covers, but it has no part for this bed, so that figure does not help you. All three are clamp-on, no drill. The ACCESS finder returns 12409 and 32409 for "Chevy/GMC 1500 8ft Bed" for the years it was queried, 2019 and 2026. The BAK listing is titled "Fits 2019-2026 Chevy Silverado/GMC Sierra 1500, 8' Bed". None of the three comes with a stated tailgate or storage-box condition, which is not the same as clearance, so check your Multi-Flex or power tailgate with the maker.

Watch-outs before you buy

The five covers with no part for this bed are recorded as no product listed, not a measured non-fit. Tyger and MOSTPLUS do not list a cover for the long bed in the application lists read on 2026-10-24, so a Tyger or MOSTPLUS cover sold for a shorter Silverado bed is the wrong length here. A cover SKU fits only the bed length it is made for, and makers round lengths differently, so match the part number, not the label. The BAK-448132 listing comes from a RealTruck search-result title and summary rather than the maker's own page, so confirm it with BAK. None of the listings says whether the Multi-Flex tailgate, the power tailgate or a Sierra MultiPro tailgate changes the answer on this bed. Ask the maker before you order.

Why a tonneau cover fits or does not

  • No SKU for this vehicle and bed length in the maker's own list; recorded as "no" with basis "no SKU in brand list", which is not a measured non-fit. The exceptions: a person should confirm before the site states a hard no
  • A cover SKU fits only the bed length it is made for; nominal bed lengths are rounded differently by makers (for example 5.5 ft, 5'7", 5'5", 67 in all mean the F-150 short bed). The exceptions: none observed

What on the 2019-2026 Chevrolet Silverado 1500 and GMC Sierra 1500 decides fit

The 2019-2026 GMC Sierra 1500 shares the 2019-2026 Chevrolet Silverado 1500's platform and bed, so the makers list them together. Where a maker treats the twins differently, the note beside the product says which truck it means.

Questions owners ask

What tonneau cover fits a Silverado 1500 long bed?

Three have a part number for it: ACCESS Original 12409, ACCESS LITERIDER 32409 and BAKFlip MX4 GEN 3 BAK-448132. The ACCESS finder names the bed "Chevy/GMC 1500 8ft Bed", and BAK titles it as an 8' bed.

How long is the 2019-2025 Silverado 1500 long bed?

The floor length is 98.18 in, with an inside width of 71.4 in and a wheel well width of 50.63 in. The GMC Sierra 1500 long bed is listed at 98.2 in.

Does Tyger make a tonneau cover for the Silverado long bed?

Not in the Tyger application list read on 2026-10-24. It shows no T1, T3 or T4 part for this vehicle and bed length. That means no product is listed, not a measured non-fit.

What is the load rating of the BAKFlip MX4 on a Silverado long bed?

BAK-448132 is listed with a distributed load rating of 400 lb and a 5-year warranty. That comes from a RealTruck search-result title and summary rather than the maker's own page.

Do the ACCESS covers for the long bed work with a Multi-Flex tailgate?

ACCESS does not say. Its finder returns 12409 and 32409 for the 8ft bed with no tailgate note. Confirm with ACCESS if your truck has the Multi-Flex or power tailgate.
