I get the silblade wipers front and rear, I replaced mine as soon as I got the Jeep. I've just had years out of them on my last two trucks and they work great in Winter. http://www.silblade.com/Rear-Blade_c_10.html
. You can pick them up on Amazon too.. they take anywhere from a week to a month to come through but worth ordering a set ready for your next replacement. The rear arm is just a little less wide than the original and a little less black, noticeable if you compare OEM and Silblad side-by-side.
