2013 GMC Sierra 1500 Tonneau Covers

Genuine GM tonneau covers for the 2013 GMC Sierra 1500, at wholesale prices. Covers are cut to the exact box length, and a 5 foot 8 inch box and a 6 foot 6 inch box do not share parts. GMT900 through 2013, K2XX from 2014 to 2018, and the T1XX from 2019 with the CarbonPro bed option.

When to replace

Security and fuel economy are the usual reasons owners add one. On a light duty pickup, two trucks with the same badge can take different parts once cab style and drivetrain are accounted for.

What sets these apart

• No hassle returns. If the tonneau covers is not right, send it back.
• Warranty intact. OEM tonneau covers keep coverage that an aftermarket part can void.
• Wholesale pricing. Most tonneau covers numbers land well below dealer list.
• No aftermarket substitutes. These are GM tonneau covers, not OE-style equivalents.

Avoiding the wrong part

A part validated on this vehicle behaves differently from one validated across a range of vehicles. Fitment questions are the one thing worth a phone call before checkout rather than after delivery. We ship from Dallas, which keeps transit times short across most of the country.
