TracRac SR Sliding Truck Bed Ladder Rack # TH43002XT-608 does not fit the 2017 Chevy Silverado 1500 5-1/2 foot bed. The difference between it and the one that does fit your truck, # TH43002XT-782, is how they attach to the bed and where the mounting holes for the hardware need to be. So you won't be able to use the 21608 rails on a 2017 model.

Since you have a wheelbase/axle spacing of 38 inches the correct hanger kit for slipper springs would be the part #HAP-105-205-01. And then for a 7k trailer axle the u-bolt kit you'd want would be the part #APUBR-8. I attached the diagram to use…
