Aftermarket rear axle locker
 

Hi

I have a 2008 F-150 RWD with a 6" lift and 20" wheels with Nitto Tires, and would like to do the following:

Install a new diff with a lower drive ratio that compensates for the large wheels
Install an aftermarket locker.

Any idea whether this is possible?

Any ideas who could help in the Cincinnati, OH area?

Thanks!
