The boggers are directional and too wide.
If you have stock low range gears and going to play in deep mud you may want to go 36" swampers, but the 38's will give you better clearance and you can always get the 4.7 gear set to help you turn them.
Boggers will require more power and have to move more mud to advance forward.
Swampers on the other hand will not dig as fast giving you a little more control before digging straight down and they work better with less power and work both ways the same.
I am turning 38's with just over 65 hp, 5.29's, but have a choice of 3 differant low ranges.
you will have to watch the clutch if you get bogged down, but this is true with any tire you use.
