2014-2018 GMC Sierra 1500 Bed Covers

Every tonneau in this collection is fitment-verified for the 2014-2018 GMC Sierra 1500. Covers ship for all three K2XX bed lengths -- 5'8", 6'6", and 8.0' -- from BAKFlip MX4, Retrax PowertraxONE MX, RetraxPRO XR, and TruXedo Pro X15.

Do I need to drill my Sierra to install one of these covers? No. Every BAK, Retrax, and TruXedo cover here uses clamp-on rail mounting that installs in 30-60 minutes with basic hand tools.

If it is listed here, it bolts on clean -- guaranteed.
