BAKFlip F1 vs BAKFlip MX4 — frequently asked
BAKFlip F1 or BAKFlip MX4 — which should I buy?
Buy the BAKFlip F1 if its balance suits how you use the bed. Buy the BAKFlip MX4 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 BAKFlip MX4?
On our rating the BAKFlip F1 scores High for security and the BAKFlip MX4 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. BAKFlip MX4: 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.
