Overview
This BAKFlip MX4 hard folding tonneau cover, part 448130, fits 2019-2026 Chevy/GMC Silverado/Sierra trucks with the MultiPro/Flex tailgate and a 5 foot 10 inch (69.9 inch) bed. It will not fit trucks with the Carbon Pro bed.
An auto latch locking system and tighter fit clamps and seals are the main changes from earlier BAKFlip generations, aimed at keeping cargo secured and water out. Because fitment is tied to exact bed length, tailgate type, and bed material, this is a cover where matching the listed specs to your truck matters more than any single feature.
- Fits 2019-2026 Silverado/Sierra, MultiPro/Flex tailgate
- 5 foot 10 inch (69.9 inch) bed only
- Auto latch locking, hard folding panels
- Will not fit Carbon Pro bed trucks
Who it's for
Silverado or Sierra owners with the MultiPro/Flex tailgate and the 5 foot 10 inch bed who want a locking hard cover with full bed access when open. Not for trucks with the Carbon Pro bed.
Strengths and trade-offs
Drawn from this product's published specifications.
- Auto latch locking system secures cargo
- Folds fully open for complete bed access
- Aluminum and polymer construction for strength
- Improved seals target better water resistance
- Fits only the specific bed length and tailgate listed
- Will not fit the Carbon Pro bed at all
Performance notes
The cover folds into sections toward the cab and locks with an auto latch system built into the design, allowing full bed access when open and a secured, locked bed when closed. Aluminum side rails and top panels with high density polymer cores are meant to add strength over earlier versions, and updated seals and clamps are aimed at keeping water out of the bed.
