Given that the differential ratio is 3.55 or 3.92 I would say yes.
But if you stop using the overdrive on the transmission you could drive it, but it will be a real dog on the uptake and the strain on the transmission will be severe.

Ok.thank you.
I used stock 3.73 differentials on my wrangler with 38″ tires for 7 years… no problems. Only that your car might use more gasoline since the overdrive will not come in until you reach 100kmh usually comes in around 80-85kmh..
The Ram will loose a bit of power but just get yourself a transmission heater gauge and your good to go. Watch the temp on the trans and you wont have any problems.
Best regards
Gunnar
