LOL. Popular Wrangler mods and fuel economy are diametrically opposed. Welcome to the club buddy! I get a measly 15 mpg on my 32's/3.73, 95% city driving. 10 mpg for 37's on a heavier rig sounds about right to me.
Ok guys I'm going to hijack this for a second. I want to get my husband some shocks for his JKU so that it rides smoother. I'm assuming Ranchos, but can you guys help me with advise on what I need to get him please?
The JKU is a lot less picky on shocks as it's a much heavier vehicle than our TJ's.
The reason you hear the Rancho's being highly recommended is due to price and being properly valved for the lighter weight TJ.
