2010 GMC Sierra 2500 HD Tonneau Covers

Genuine GM tonneau covers for the 2010 GMC Sierra 2500 HD, 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 HD through 2014, K2XX HD from 2015 to 2019, and the T1XX HD from 2020.

Symptoms to look for

Security and fuel economy are the usual reasons owners add one. On a heavy duty pickup, single or dual rear wheels, gas or diesel, and cab configuration divide this group more than the model year does.

What sets these apart

• Returns without a fight. We would rather fix a tonneau covers order than argue about it.
• Covered by GM. On tonneau covers that coverage is worth more than the price gap.
• Real wholesale. The same tonneau covers your dealer sells, at a fraction over our cost.
• OEM, not lookalike. With tonneau covers the difference shows up on installation day, not in the photo.

Ordering correctly

Genuine GM parts carry the factory part number, so supersessions are documented rather than guessed at. Run your VIN first. One vehicle can list several nearly identical parts and only one is correct. Because we ship centrally, a heavy part costs less delivered here than from a coastal seller.
