BAKFlip F1 vs Extang Solid Fold ALX — frequently asked
BAKFlip F1 or Extang Solid Fold ALX — which should I buy?
Buy the BAKFlip F1 if its balance suits how you use the bed. Buy the Extang Solid Fold ALX if its balance suits you better. Both are the same type of cover, so the decision is about execution rather than category.
Is the BAKFlip F1 more secure than the Extang Solid Fold ALX?
On our rating the BAKFlip F1 scores High for security and the Extang Solid Fold ALX scores High. Treat that as resistance to an opportunist rather than as a safe — no tonneau cover stops someone determined with tools and time.
Will either of these fit my truck?
Both are sold per truck and bed length rather than as one universal part, so the answer depends on your year, model and bed. Most full-size & mid-size beds — confirm your year and bed length. Check your exact fitment before ordering either.
Do either need drilling to install?
BAKFlip F1: Clamp-on, no drilling. Extang Solid Fold ALX: Clamp-on, no drilling. Mainstream covers clamp to the bed rails and need no drilling, which keeps them removable and the truck's finish intact.
