Get the AISIN Trans, Factory Rear air Ride and 4.10's. You WILL thank me!!!
The AISIN is in many Medium Duty applications and is truly bullet proof.
Get the larger fuel tank as it WILL bring you more than $295 on future sale.
I don't think RAM offers the 3.42's any longer.
Why 4.10 gears? You’ve got 4.10 gears pulling your rig with only 865 lbft of torque and it likely works fine. With 1075 lbft of torque 3.73 would work very well for towing. At 1800 rpm the Cummins is capable of making 368 hp ..... you certainly don’t need to be running at 1800 rpm while towing a 16000 lb fiver down the highway. 3.73s would put the engine at 1550 rpm at 65 mph vs 1700 rpm with 4.10 gears.
WHY??? Because the 3.42's are no longer available. 3.42's with AISIN are AWESOME with the lower starting gears and then locking in 5th at 60 turning 1,750 rpm the same as my 4,10's in 6th.
I tow a lot at 60 so 3.73's would be too low of RPM.
