I’m getting ready to swap in Yukon 4.88 gears onto my 2009 wrangler. Just looking for advice and things to look out for during the swap.
 
You will have to recalibrate your speedometer after replacing the gears so the your speed reads correct. Also if you have a automatic trans it won't shift correctly if the speedometer is off.
