BAK Revolver X4s vs BAKFlip F1 — frequently asked
BAK Revolver X4s or BAKFlip F1 — which should I buy?
Buy the BAK Revolver X4s if you care most about bed access, and it is the cheaper of the two. Buy the BAKFlip F1 if you care most about security. They are different cover types, so decide the type first — that choice matters more than the badge.
Is the BAK Revolver X4s more secure than the BAKFlip F1?
On our rating the BAK Revolver X4s scores Medium for security and the BAKFlip F1 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?
BAK Revolver X4s: Clamp-on, no drilling. BAKFlip F1: 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.
