Eaton/Detroit makes a locker and also a helical limited slip called the TrueTrac. A lot of people love the TrueTrac and I plan to have one installed in my axle as soon as I can afford it. I'm getting quotes of around $1,500 to get one installed.
Powertrax makes a helical limited slip also and it's a couple hundred bucks cheaper but I can't find any reviews on that one. It's called the Grip PRO.

I would recommend the Eaton truetrac, I really dislike the factory E-locker in my current truck. For on-road winter driving a limited slip diff is my preference with the true trac topping the list. Combined with traction control the truck will do anything I need/want. The e-locker is frustrating on icy roads, with it off you have a one wheel wonder going nowhere, and with it on a locked diff that doesn't like turns due to no differentiation. The owners manual basically says leave it off on road. I sure wish the factory would offer the true trac as an option. Good Luck, Russ

The Sterling 10.5 should also be a 35 spline axle. Just about all the major manufactures make a locker for it, Eaton, ARB, Lock Right, and of course Ford.

Welcome to FTE, Leo21.
The good news is that there are many limited slip and locking differential options available for the Sterling 10.5 differential. I would avoid the factory limited slip (if you find one in a salvage yard), they aren’t very good. All aftermarket units are superior.
The factory locking differential is OK. My only complaint is the truck computer automatically unlocks the differential above a certain speed, 8 MPH if my failing memory serves me well. Setting it up on a separate switch to allow you to have full control of the unit would work very well.

I would go with a Detroit Locker, I have one in my truck and I love it, one of the best modifications I ever did. Strongest and most reliable locker on the market, the Yukon Grizzly locker is also good, same design just a different brand.

Or you can put it on an upfitter switch and take the nanny out of it like I did. On or off any any speed.
