Wading depth

What is the maximum wading depth of a Chev Silverado 1500 2021 model

Generally speaking you do not want to wade through standing water over the hubs.  The vents to the differentials, transmission and transfer case are about 5-6 inches above that point on mine, check yours.

Our first experience with fuel injected trucks was with our first new truck for our business. A 1985 Ford extended cab 2WD. It gave new meaning to wading through a puddle. The way the intake was you hit water wrong it’s going in the engine. We found out the hard way on a pipeline. Of course I wanted to pull it through with my tractor. My father’s favorite line was always let’s see  what she’ll do. It was until it wasn’t.  After pulling the plugs and letting the water out we drove it home. At least after my brother rebuilt it with additional goodies it was more fun to drive. You could tease my father about to a point. Then you’d better stop. Some of the joys of a family business.

Okay, so I just read the owners manual for the 2023 GMC Sierra 1500 (stock) and on page 74 there is a caution section that says don't drive through stand water that is higher than the hubs. I measure that height at the rear tires and taking what the manual cautioned into account approximate fording/wadding depth is 16" at the center of the hub; so most likely 14" to 15" is a good conservative guess at what is safe for similar trucks that are in unaltered factory condition.
