Question:

I own a 2015 GMC Sierra, 6.5 bed with a Bakflip MX4 cover. Im interested in the Thule Trac Rac SR rack system. Your website shows that the Thule is compatible with the bakflip in a ram truck but I wanted to make sure it also was ok on the GMC. If not, Im interested in any other rack that would be ok with the bakflip. Thanks.

Helpful Expert Reply:

It is; the BAKFlip MX4 Hard Tonneau Cover # BAK48121 that fits your 2015 GMC Sierra 1500 is indeed compatible with the TracRac SR. The reason why is the MX4 installs inside your Sierra's bed rails, leaving the top free, and the TracRac installs on top of the bed rails so there won't be any interference. The correct part number for the ladder rack that fits your '15 Sierra with a 6-1/2 foot bed is the following:

- Thule TracRac SR Sliding Truck Bed Ladder Rack # TH43002XT-781
