The shifters are close to 6-8" tall, but they're also mounted high on the trans and clear the dash by 3-4". I have to lean over to tap them in and out of ranges. Nothing too bad and about as tall as the stock shifter while allowing me to know what range/axle selection I have and also somewhat out of the passenger's "oops I kicked it" range.
Also picked up a set of 16.5x9.75 slots for the 37s. They were well priced locally and that never happens so I bought them an hour after they were on Craigslist. Not sure if I want the black steelies or the slots and it's always nice to have options. These might push my tires out too much on the late model rear axle for my taste, but we'll see.
