3.21 with stock 20's?
 

hey guys just got my truck and was looking into the the specs and shopping for a hitch. just noticed that according to the sticker that my truck has 3.21 rear end. Is that possible with the 5.7 hemi and stock 20 inch rims. i got crew cab slt big horn edition.

how much do gears roughly run to switch them out to 3.92?

average 1200 +/-

need the ring and pinion, also the spacer kit

if you have 4x4, then double that

How much are you going to tow, I have the same set up and tow my boat [loaded 3,500--4,000 lbs ] Have no problems pulling or coming off the ramps?

guessing he wants more torque and not really the pulling cap...

well havent done any towing with it yet but will find out i guess. got a 26 ft pontoon boat prolly about 3000 dry weight and 26ft Proline runabout which probably is about 5000lbs dry. right at the trucks capacity. which i wont tow much but be nice too know i could. was just doing some reading on the boards and didnt even thing about gear ratio when i bought the truck. got a steal on it so i could really care less.
