new Gears
#2
You can get gears at most performance accessory place or aftermarket sales place like Summit Racing, Jegs, 4 Wheel Part and Wholesalers, Randy's Ring and Pinion, so on and so on. You'll spend around $200 per axle for gears and anywhere from $200-$500 per axle installed. This mod is worth the money in my opinion. You need to have a shop that you trust install the gears, there is a lot involved with it. Sorry this is so long, but I hope it helps.
