I wouldnt say one gear is better than the other as it depends on your vehicle and mods. A Mod SL lifted wk running 35's and 4.88 or 5.13's would be better than 3.73's but a stock WK would be better with 3.73's vs 4.88's or a deeper gear. Everyone is excited for these as this is the first aftermarket gearing offered to us WK folks since the WK came out. So for people who are lifted with bigger tires a deeper gear will benefit us big time, ie. Better MPG's, better low end power, etc.
2010 JKU - Stock for now
2005 WK - 6" lift, 35" BFG's, a lot more (SOLD)
