Tonneau covers that fit the 2019-2026 Ram 1500 6.33 ft bed

11 tonneau covers fit and 11 do not, by the makers' own fit charts. Among the fits: 5 soft roll-up, 3 hard quad-fold, 2 hard tri-fold, 1 soft tri-fold.

By the FitsMyTruck team. Fit answers come from the makers' charts and install guides, with 9% of the entries taken from retailer listings where a maker publishes no chart; part numbers are checked against the live listings, and every page is reviewed before it goes up. Last reviewed Oct 24, 2026.

Tonneau covers for the 2019-2026 Ram 1500 6.33 ft bed: what to know first

Owners of the 2019-2026 Ram 1500 with the 6 ft 4 in bed, a floor length of 76.3 in or 6.33 ft nominal, have 11 part numbers from five makers that fit: Tyger, MOSTPLUS, ACCESS, BAK and UnderCover. None fits only with a condition, and the makers publish 11 exclusions. The truck is offered in Quad Cab and Crew Cab, with the RamBox cargo management system (available) and a Ram multifunction tailgate referenced as an available option. RamBox is where this bed differs from the 5 ft 7 in bed. For the 6 ft 4 in bed, the ACCESS finder lists no RamBox part at all and offers RamBox only for the 5 ft 7 in bed. That leaves RamBox trucks with no confirmed cover for this bed.

How to choose for this bed

The 11 part numbers fall into four types. Soft roll-up, 5: Tyger T1 (TG-BC1D9047), ACCESS Original 14249 and 14299, ACCESS LITERIDER 34249 and 34299. Soft tri-fold, 1: Tyger T3 (TG-BC3D1045). Hard tri-fold, 2: MOSTPLUS 3-Fold (M042342-SH) and UnderCover UltraFlex (UDC-UX32009). Hard quad-fold, 3: Tyger T4 (TG-BC4D4418), MOSTPLUS 4-Fold (M04234202-SH) and BAKFlip MX4 (BAK-448225). Published load ratings run from 350 lb on both MOSTPLUS covers to 400 lb on BAK-448225 and the UltraFlex, which is the highest listed. Cover weight is published for Tyger only: 26.7 lb for the T1, 36 lb for the T3 and 78.26 lb for the T4. Warranty is 1 year on MOSTPLUS, 3 on LITERIDER and 5 on the rest. Tailgate is the main option that sorts the choice. ACCESS 14299 and 34299 are listed for the multifunction tailgate, BAK-448225 is listed as compatible with it, and Tyger excludes it. The MOSTPLUS 4-Fold listing warns that some multi-function tailgates may not close electronically and may need closing by hand. Weigh that before choosing a hard fold.

Watch-outs before you buy

The makers publish eleven exclusions. Seven are Tyger: the T1 and T3 each exclude RamBox and the Multi-Function (split) tailgate, and the T4 adds TRX with RamBar and the RAMBOX cargo management system. Two are MOSTPLUS excluding RamBox. Two are ACCESS entries saying no RamBox part is listed for this bed, which is a gap in the list and not a measured non-fit. The result: no cover is confirmed for a RamBox truck with this bed. BAK-448225 and UX32009 do not state RamBox status, and BAK-448225 is not compatible with the Ram TRX Bed Bar. Our source for both is search-result titles. Confirm RamBox status with the maker before ordering.

Why a tonneau cover fits or does not

  • 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
  • Ram 1500 with RamBox needs a RamBox-specific cover SKU; standard covers exclude RamBox. The exceptions: BAK-448227RB and ACCESS 14199/34199 are RamBox-compatible
  • Ram 1500 with the multifunction (split) tailgate excludes some covers; others sell a separate SKU. The exceptions: BAK-448226/448225 and ACCESS 14289/14299 accept it

What on the 2019-2026 Ram 1500 decides fit

Before you buy tonneau covers for a Ram 1500

Questions owners ask

Is there a tonneau cover for a Ram 1500 6'4" bed with RamBox?

None is confirmed. ACCESS lists no RamBox part for the 6ft 4in bed, Tyger and MOSTPLUS exclude RamBox, and the BAK-448225 and UX32009 titles do not state RamBox status. Ask the maker first.

What tonneau cover fits a Ram 1500 6'4" bed with the multifunction tailgate?

ACCESS lists 14299 and 34299 for "Ram 1500 (w/ Multifunction Tailgate) 6ft 4in Bed", and BAK-448225 is listed as compatible. Tyger excludes the Multi-Function (split) tailgate.

How long is the long bed on a 2019-2025 Ram 1500?

The floor length is 76.3 in, 6.33 ft nominal. Tyger writes 6'4" (76"), MOSTPLUS writes 6.4FT and ACCESS writes 6ft 4in. Buy by part number.

Which 6'4" Ram 1500 tonneau cover has the highest load rating?

BAK-448225 and the UnderCover UltraFlex (UDC-UX32009) list 400 lb. Both MOSTPLUS covers list 350 lb. Tyger and ACCESS list no load rating, so 400 lb is the highest listed.

Does the Tyger T4 fit a Ram 1500 with the 6'4" bed?

TG-BC4D4418 is listed, at 78.26 lb with a 5-year warranty. Tyger excludes 2019-2024 Classic models, TRX with RamBar, RamBox, the RAMBOX system and the Multi-Function (split) tailgate.
