Question:

Is this the correct setup for a 2018 GMC Sierra 1500 2 wheel drive Crew Cab with a short box? Also what is the part number for extra air line that will work for this product?

AirLift rear axle air bag suspension kit # AL88211 only fits the long bed version of your Sierra so for your short bed pickup you'll instead want to order kit # AL88204. This is a no drill installation unless you have a 5th wheel hitch; in that case you will need to do some drilling.

For extra air line you can use any brand of standard 1/4-inch air line like # F99ZR. I recommend using an air line cutting tool # AL10530 to ensure clean leak-free cuts.

I also recommend that you consider adding compressor # AL25856 to let you get the most out of the air springs. Having an on-board compressor means you can easily find the pressure sweet spot as you tow or haul, without having to pull over to air up the bags manually.
