Gearing question!

Hey guys so i just traded my wrangler, thank god, for a 1996 gmc 2 door yukon. It came from a local mufflers shops owners son. It has a 350 (non vortec?) and rebuilt trans or so he says. it has brand new 38 mud graplers and im curious, he said it has 4:56's...How would these hold up in the mud on occasion?

1996 is obd2 diagnostic system and has a vortec engine in it. They should hold fine for you
