Sterling 10.5"
So, if you were switching gears from a 3.73 in an Excursion with the V-10, would you go right to 4.56 or 4.30? Gas mileage is not a concern, and it's in a 2WD.

The least expensive locker for the 10.5" Sterling is the Powertrax Lock Right. The Lock Right for my 10.25" Sterling was about $300. I had it installed at the same time as the gear change.
A gear change with a Lock Right install should cost about $1000 for your 10.5", depending on local labor rates.
The Lock Right fits in the stock open carrier, which is why it costs alot less than the comparable Detroit Locker. Both the Detroit and the Lock Right are all-gear ratcheting automatic lockers. There are no clutches to wear out and no electric or air system to install to active the locking mechanism.
I've been quite happy with the Lock Right in my F350 for the last 12 years.
