There was an argument long ago on the OG Hot Boat about changing out the keys versus running up the torsion bars and how changing the keys didn't affect the ride like adjusting the bars did... It was a dumb conversation and the person failed to understand that changing the keys essentially is the same thing as running up the bars because of the different indexing of the holes... the truck won't get taller without giving some extra twist to the bars...

There are lots of offroad places selling the keys for a few hundred bucks when you can got to the dealer and get them for 1/3 of the price or less. I have even seen some that they ground the GM number off of and resold them. Gotta love it!!!
