If I only remove my rear sway bars will it improve my offroading capability?

 

font and back you need to remove...and its not the capability its the amount of independent wheel travel on each side...

 

Removing the sway bars will let your wheels move more freely and give you better articulation. This is usually desirable in off-road situations. Make sure you put them back on when you drive ont he road though, or you'll notice alot of body roll.
