The BAK Revolver X2 is a hard roll-up tonneau cover: patented interlocking aluminum slats under one-piece DualShield 60-grade vinyl, locked down by rotational locking rails and automatic slam latches, that still rolls to the cab when you need the whole bed. BAK makes it in truck-specific versions for full-size, mid-size and heavy-duty pickups, each cut for one bed length and, on some trucks, one bed option such as RamBox, deck rails or the cargo management system. Every version is rated at 400 lb spread evenly, clamps on with no drilling on most trucks and carries BAK's 3-year warranty.
