Changing gear ratios

[20silverado]

Hey everybody I’m new to the forum but I have a 2020 silverado 1500 4wd and I’m wanting to change my differential ratio from 3.23 to 3.73 and I know doing that since it’s 4wd you have to change front and rear. Does anyone know where I can get this done or atleast get me pointed in the right direction? Appreciate any help or advice

Any good drivetrain shop should be able to do the work.

I haven't found a shop that has gear swap kits available for our models yet.  If you find one, please post for everybody to have.

Prepare to pay to a pretty penny to tune the truck for the changes.

I believe that only the rear gears are available aftermarket as no one makes anything for the front. You will have to find a wrecked truck to swap the axles from it. Keep in mind that you will have to install the Pulsar to adjust the speedo for the gears.
