Hey fellas. I got on a website called moesperformance.com and checked out 3.92 gears with limited slip and he said it would be $840. Is this right or is there a better place to get the gears ? Also i have 3.21 now, but should i go 3.92 or 4.10 ? I dont want to kill my gas mileage. Right now im city with highway 50/50 and im getting 17 mph reg cab hemi. If you guys can throw some advice my way, id appreciate it.

DoctorDiff.com, Auburn Gear, Moser Engineering or Strang Engineering. As far as gear selection, why, Are you towing, putting big tires on building a muscle truck?

www.airram.com write in the search area "vip gears". they provide the best prices and free shipping and in some areas they can install so enjoy

and if u think of it when you go with higher gear ratio you just get higher rpm but at the same time u r truck weight is lighter i mean there will be no load on the engine while stopping and going. also, on the highway the truck wont shift down a lot to maintain speed. i had on my old truck 4.56 gears and it was the same but better power and better acceleration. trust me it was the best thing i ever did.
