Gear Vendors overdrive

like i said i have two good friends that run GV units. they love them.. they run 3.55 gear and a tall tire and it mellows them out some (2.76 IIRC). i'm sure there is an instance that splitting gears may be good.. towing maybe? but to me the delay is too much for anything else really. plus for that money i think i would rather have something that gives me both a better first gear and a better OD ratio... but hey thats me. if you think splitting gears with a lame OD ratio and no improvement in first gear is great who am i to argue go spend the money on a GV unit.. they are strong and my friends don't have issues with them.. well other then a couple stupid lil thing..
