I wonder why they don’t want to do it. The 9.75 axle is awesome and used to be very commonly paired with the 5.0

Select fx4 then try.

I orderd the 3.73 locker with my 22 5.0 4x4 RCBS.

Did try that, unfortunately they assured me I’m unable to get on a 2023 Model. Just placed the order with the FX4

We're lucky they're still building a RCSB at all.

true...but trying to find a 5.0 RCSB 4x4 is hard....a ton of guys build them for race/fast street trucks.

Agreed, had to go with the 3.31 gears that comes with fx4.

I let my speed demon buddy drive my 5.0 RCSB when I got it.

That was his takeaway... "Slam it and make it a race truck"!

Hello everyone,

Was placing my order today but noticed when I tried to order the 5.0 engine, it wouldn’t allow me to select the 3.73 Electronic-Locking Axle. Is this not available in a RCSB ?

I have a 2021 RCSB FX4 with 5,0 10sp and 3:73 locker. I dont know if Ford changed something or not. The 3:73 was is awsome with that combo. MPH didnr suffer either.

Yeah that’s the exact configuration I wanted but not available for the 2023 with 3.73. Had to go with 3.31

CAFE MPG Standards can't be meet if they keep selling trucks with gear ratios like 3:73/3:55.

landmark fuel economy standards which follow President Biden’s executive order to drive American leadership forward on clean cars.

I opted for the 3.31 E-Lock since most of my towing will be off road at low speed in low gear anyway. And for just straight off-road climbing... also 4x4 Low.

The 5.0 in a RCSB (400lbs+/- less than larger trucks) has no problem snapping your neck off the line with 3.31 on the street. When you stab the throttle at 45 MPH the 10-speed transmission is happy to jump from 8th gear to 3rd gear in an instant and you'd better be ready!

I would love to drive a 3.73 just to see the difference but I'm pretty happy with the 3.31

I'm averaging 20-22 MPG on the street and when I REALLY baby her on a freeway run, I've pulled 28 out of a tank of gas.

Towing on the street... 15 to 19

I’ve got my 5.0 egoboost with 3.31s and it accelerates just fine I’m lowering mine and using airbags as I use it for work and am getting in and out of my bed everyday loading and unloading wheelchairs with a ramp. Getting old I guess.
