2017 GMC Sierra 1500 CrewCab TracRac SR Base Rails Installation  


These things are absolutely not lining up. It seems like a fairly simple install, but Ive looked at it myself and have had someone else take a look and we cant get it. I received a diagram with the instructions that says Sierra 1500 Crew Cab see reverse, and there is nothing on the back page. It seems like the way this should be done is the bolt into the rubber block with the steel pocket nuts at the front, and the bolt into the steel piece that you screw into that lines up with the stake pocket that you put the bolt into goes at the back. Is there a rail diagram you can supply for a 2017 GMC Sierra 1500 Crewcab 5.5 foot bed? Would be very appreciated.


Expert Reply:

The TracRac SR is bed size specific not cab style specific but for your 5-1/2 foot bed, you should have the TracRac SR Sliding Truck Bed Ladder Rack - Full Size Pickup Trucks - 1,250 lbs # TH43002XT-782. I reached out to the manufacturer and they said you will use the T900 holes.

If you need further help, please let me know.
